@@Hanitcal69 Chinese proverb. "Our kids work in sweatshops making shoes to sell while American kids steal them and work on their gender identification." Got it.
Great video!! As a sneakerhead and someone who own the Adidas 4DFWD, I can say it is worth every penny. This specific model has Adidas’s and Carbon’s newer 4D midsole tech which has a different structure than the first 4D midsoles from Adidas, which I believe is also used in those 4D Fusio. Basically, the newer 4D tech is more springy (making it more suitable for their running shoes, hence why its in the 4D FWD), and is actually more comfortable than the original version. I love my pair of 4D FWD. Yes, things do get stuck inside the midsole, so you don’t wanna put it through dirt or mud. It is very much a city walking/running shoe. But, it’s a small price to pay for tech that’s really pushing the boundaries, and a still comfortable shoe.
Thank you very much for the analysis. I have a small note that will help you analyze your shoes in more detail after the cut. You need to make cooling for the cutting machine. This is necessary because during cutting the temperature of the cutting blade increases and it thermally deforms the cut sites for materials made from materials with a low melting point. Thank you !
i have s few pairs of the OG 4d -- and a pair of the 4DFWD. RE: 4D - if you're looking for springy bounce, look elsewhere. But if you want firm, supportive, all-day comfort, they're amazing. RE: 4DFWD - The FWD stands for 'Forward" -- and there's a propulsive springiness you can feel - especially if you've spent time in the regular 4D. It's 100% true that dirt and dust get trapped in the midsole. You could probably soak them in a shallow pan, but I've never tried it. All in all, it's great tech - and I think we'll see a lot more... as soon as someone can scale it.
Thanks for doing the vid! Great to see your take on them. I'm a big 4D fan and own several pairs. This original 4D sole is a lot firmer than the new generation 4DFWD and it's "squish" factor is totally different league. As an experiment, I actually soaked a brand new pair of 4DFWDs in boiling water for a few hours and it totally changed the softness of the 4DFWD structure. I use it for casual walking and it is by far the best in comfort for all day, everyday wear!
Love how every time he says "far from scientific" when these are the most scientific tests I've seen regarding sneakers without auditing R & D for every major sneaker brand
Ive been saying this so long it seems he won’t do it. Someone should do it I would sub so fast. Just got some high tops from Axel Arigato made in portugal out of calfskin I love them.
I agree, 3d printing the midsole is kinda neat, but without the customization it doesn't seem like it is really making the best use of the technology. I absolutely see a potential future, really could be done now at least to some extent, where you have a shoe store with just some samples and the equipment like treadmill for mocap, pressure plate and 3d scanner to measure various aspects of your feet and how you walk and run, then you pick an upper, customize that, and like 30-60 minutes later after all of that is fed into a computer, you have what should be the perfect shoe for you, at least as far as support and comfort are concerned.
Making 3D printed shoes on demand is going to require an expert in footwear manufacturing and 3D printing in-store at all times. I can see maybe a few rare specialty stores that can do this but these shoes would be incredibly expensive. Resin 3D printing is also ultra-toxic, putting a resin machine in a consumer store probably wouldn’t meet safety guidelines.
I have one pair of 4DFWD and its forward spring technology is noticeable when I run. it felt like something was pushing me forward when I first ran with this shoe.
The fact that they even said "sneakerhead" in their marketing told me everything I needed to know about what kind of culture they were hoping to snag with this line. If they wanted to implement this technology meaningfully they would probably be hiding the lattice structure behind a wall to prevent the debris from entering the shoe and purely just provide interesting support. They wanted something visually striking to match their marketing standards for a large investment. I hope the future where they integrate this tech into their standard styles of shoe is decent, but I personally put function on the same level as form.
Didnt they use that special printing process to make the models for the action figures in Small Soldiers. Its been a while since i watched the scene but i recall it looking similar
this is the result of the hype around 3D printing a few years ago. eventually i think you’re right; parts of shoes will be printed in or near the location you buy them. But i think that will come fr either a niche space or a smaller company first. These mega companies already have the supply chain in place, there’s no need to disrupt themselves…but a new player in the game who wants to be the Build-a-bear for shoes?! hell yes
4D Fusio is a great pair indoor workout shoe, best I have ever had. With bouncy midsole often you're sacrificing the ankle stability, and 4D Fusio hits the right balance for me. I have gotten the other pair of 220$ Adidas 4D shoes, which is a bit bouncier -- imo less great for training purpose. I sound like a blindsided advocate, but I really love my 4D Fusio
I recently purchased these shoes, acquiring them just yesterday. When comparing them to my previous pair which is Adidas Ultraboost, I've noticed some differences. The 'Fusio' shoes feel excessively hard and firm, making them less comfortable than I expected. Additionally, they seem unbendable, lacking the flexibility I prefer in footwear. Moreover, I've observed that the fabric near the heel area is overly stretchy, which inadvertently causes my foot to slip out easily while wearing them."
Hi super cool videos :) two comments 1- historically DLS is the standard 3D printing is super old 🤯 not as FDM 2- as you said in your intro, the 3D network is designed to push the foot forward, did you try to test your rebound tests with an angle ? Like 30° this way you while be in the optimal direction for full rebound. It's so cool to see how the videos evolved time :) take care. Last question, I'm a great fan of Alexander McQueen sneakers. By any chance, could you make a review one day ? I want to know if it's real leather or coated one.
I have very wide feet with a high arch. It is almost impossible for me to purchase a pair of comfortable shoe. I have been talking about the future of 3D custom made shoes for years. The advantage of 3D is the CUSTOM fit. Shoe manufacturers should offer the option of custom fitted shoes to all 3D shoes.
The reason the ball drop test didn’t work is probably because you dropped it on the heel, where the lattice is spread more apart, absorbing the energy. When you run, you don’t heel strike so if you were to cut off the top of the shoe and drop the ball at the front, it would most likely bounce around the same height as the other mid soles
I know this sounds weird but I would be curious as to how these shoes would hold up after being in the sun for a few days/weeks. These resins they use cure with specific wavelengths of light, and also degrade from exposure to light, so it's possible these shoes could crumble eventually if left in the wrong conditions.
As someone who loves sneakers and has been trying to max out on comfy tech AND someone who really likes Adidas - I think these shoes are just a great proof-of-concept right now. In practical purposes, I’d rather just go with an Ultraboost because the advantage isn’t significant. The biggest downside for me for this tech is that it has holes! And no matter how careful you are, stuff will go inside them. Imagine spiders crawling up in there and nesting, for example. The best way to make this tech more practical for daily use is to encase the outsole like they encase the Boost in Yeezy 350s. They did it half-way here, but I think that would be the real deal-sealer, and that would finally make the conversation about its comfort over other tech. Right now it has a new sort of impractical disadvantage that other outsoles don’t.
There goes that cat, I missed him...! 😊 I really enjoy your work my man, but I get distracted often by you cat, that seems to be looking at you like you're 'Looney' or something; thinking its just you two in the room...! 😆 But he seem's to be loyal & supportive in your issues...! 😄Am I the only one that has mentioned that...? 🤔
Well yeah it’s cool tech but on the other hand once it’s established and the printing machines are ready to go… it’s really just light curing a polymer so…. Very easy to mass produce and just a different way to a mold.
All resin printers use light; the difference between Carbon and other resin, it's called CLIP (Continuous Liquid Interface Production) which has a membrane that allows printing in less than 25% of the time of regular resin/FDM and the product is printed at the *molecular* level so the finished unit has the same structural strength as the original material so there is no weak points or characteristic printing issues like delamination or needing to smooth parts - parts come out of CLIP ready to use.
This shoe uses the original 4D midsole tech which does not have very advanced forward spring technology. The more modern Midsole with what adidas call the 'Bowtie Pattern" can be found on the 4DFWD are a massive generational leap in comfort. I've owned both styles and the newer tech is simply superior in every way. Great Video!
The lattice structure and the material used in the 4DFWD is so cool how it launches you forward! I just got some XPLR Boost and for a big guy like me they are so comfortable.
I had some 4d shoes, they are pretty cool and are also pretty comfy in a firm kind of way. The only problem is (like you said) the holes get stuff stuck in them super easy, including a worm which I saw coming out of them once!
Came for the shoe, stayed for the cat. Quick thing on 3D printing: stereolithography (SLA) printing has actually been around for decades, and you can buy a SLA (or MSLA) printer for really cheap. Carbon printers have some extra magic but even the cheap Elegoo printers work great for the home hobbyist. Edit: I mentioned this in another thread but I’ll add it here: watching a physical thing get pulled out of a vat of goo using nothing more than light is like magic. It’s been around a long time but it’s still absolutely amazing.
Word. I remember seeing stereolithography footage on science & engineering programs like NOVA when i was a kid; at least the early-90's, maybe earlier. Was *very* sci-fi at the time, seeing a skull or whatever emerge from the goo.
For a while, before common man got a hang of it, the cheaper units were locked behind patents. At first, they weren't even on the markets, simply locked away. In theory, we could've had 3D printers back in the 80's, sure, not for Average Joe, but none of the tech that was required to get one running is new. And at that, back in the early 90's a few CNC mills were converted to use extruders to make precise casting blanks for machining plastic bits. Funny how that works, huh, old scrooges plopping their feathery arses on tech and locking it away for no good reason.
@@aserta with FDM printing, Stratasys got the key patents and built their business around them-they didn’t just sit on them. But I agree the 26 year duration of patents is waaaaay too long, and the giant wave of innovation that began in the 2010’s was because the Stratasys patents expired. Open-source companies like Prusa Research have pushed FDM technology ahead far more than Stratasys ever did. Patents should be good for 3-5 years, tops.
as an FYI, Carbon is not SLA technology, it is DLP. The processes are different and comparing an Elegoo or hobbyist printers to a Carbon machine is such a bad comparison you really shouldn't even compare them.
@@Fishbone8891 Carbon’s magic isn’t DLP; you can get DLP in hobby-grade printers these days. It doesn’t really matter if the UV light comes from a laser (SLA) a masked UV source (MSLA), the magic in Carbon printers is their management of oxygen. It allows them to move the curing away from the UV source so that the printer doesn’t do the raise/lower cycles after each layer. A traditional SLA/MSLA printer spends most of its time un-sticking the part from the UV source whereas a Carbon printer can just pull continuously-it’s much, much faster.
The idea of going to an Adidas store and getting a custom sole that fits me is very, very exciting. I hope that's something we see in this lifetime. If nothing else, it'll put some pressure on Dr. Scholls.
There's a fitness store my partner goes to in Prague which has a machine to measure her foot, how she runs, and puts weight on different areas of her foot, and makes a custom insole based on the measurements...
I have been through two pairs of 4D running shoes and am about to buy a third. I prefer them, firstly, because the midsole is super durable compared to Ultraboost, so I don't have to coddle them on runs. The second thing is the FWD midsole is less about vertical rebound and much more about 'forward efficiency.' It's not as springy, but I find over a long run I become less fatigued with the help of the forward propulsion. And the targeted densities. Third is, because I give these a light clean regularly, they stay much fresher than the white foam midsoles of other shoes. Foam midsoles stain really badly over time, so running warm, soapy water through these once a week makes them fresh for the life of the shoe. And suprisingly great underfoot ventilation.
5:10 You do *not* end up with a stronger, better product than with extrusion printing. Hoffman Tactical has done extensive testing on 3d printed materials and liquid resin printed materials are consistently less durable than extruded materials. The only benefits are layer adhesion and smoother finish. The materials themselves are less durable by a large margin, and they are much more expensive to produce.
Could you please cut in half a pair of Zellerfelds they're also a 3D printing company but the diffrence between their footwear is that they are 100% made in a 3D printer and (supposedly) made out recylebale materials i would have been very intrested to see your dissection and review of it Btw loving your videos ;)
I remember when Adidas launched this product in 2015. Their was hype they would have these 3d prints in store to custom make shoes within 5 years. I don’t think they will not make custom shoes any time soon.
@@Winford.Studios Vivo is currently a trial run and they need to accept you as “pioneer”. While Pangaia’s has better “availability” but their are still two issue. The whole sneaker is 3d printed which I would imagine affect comfort and the quoted availabilily for shipping time is anywhere from late October to mid January.
I hope this takes place soon, because there's an obsession for soles tech but the upper part of the shoes are becoming like clowns' shoes (narrow and pointing upwards).
I don't think your performance tests are really able to capture the performance characteristics of this shoe. As you can see in the footage from Adam Savage that you linked, this structure rebounds at a particular angle, not evenly in all directions like a foam. The ball and bar drop tests can work to test rebound of foam, but if this material rebounds at an angle, you're only going to get a reduced percentage of rebound in a test where the impact is coming perpendicular to the material. I'm not sure how you could really adjust this sort of garage-science test to test for the angular rebound these lattices are meant to maximize, but I'd be really interested to see how they compare to foams for rebound in the angles that matter when worn.
Adam Savage has a video on his Tested channel where he visits one of Carbon's labs and talks to some of the engineers about their tech and other fun stuff. Definitely worth a look!
I think the newesr is 4DFwd2. I always wanted to try these 3d printed midsole and i just got myself for 100usd. This video came in clutch before i get mine tomorrow
I wonder if they will eventually be able to print them to fix posture. Like gradually changing the shape like invisaline braces to slowly fix a incorrect joint or something. Maybe even correct bunions over time.
Have had several pairs, best so far is the ultra4fwd's-a lot more 'bounce' than the original 4D's, and the upper on the ultras is much more comfortable. 4D is nowhere as squishy underfoot as ultraboost, and feels heaver underfoot. More of a lifestyle shoe, I go with Hoka's for a run.
I don’t understand this fascination with squishy athletic shoes. It’s backwards thinking. The squishier the shoe, the lazier the muscles in the feet become. Also, injury becomes more concerning due to the instability of squishy. Yet all RUclips athletic footwear reviews measure the validity of a shoe mostly based on how squishy it is. 🙄
Being a die-hard boost head Ultraboost was something I wore exclusively. They are confortable, stylish, and versatile. However as I get older I find, to my dismay, the amazing softness of the midsole is giving me foot fatigue on the top of my arches and also the big toes area. 4D midsoles alleviates all of that. They have a firm give when you first step into a new pair, but it also provides a sensation of "embracing" your foot. They provide all day comfort and support without feeling mush-y. And trust me, they get more comfortable as you wear them in. So far I have had zero problem with materials being stuck in the midsoles in all my 4D sneakers. The price is really stiff yes, but they are definitely worth it when they go on sale.
@@placeholder3863 No that's not the case at all. It's about finding the right cushion setup for your age, and for the right occasions. I wore boost predominantly for the longest time, and they were the bee's knees. But as I'm over 40 now I need something firmer if I were to be on my feet all day. Plush cushioning is still great when I go for a walk or a jog.
just saying here, I got the micro adjust belt and it's great honestly. really nice leather and measured to fit is right on. he didn't pay me, but im glad i got it. if you haven't had high quality leather before, it's very cool!
So they use a resin printer to make them. We've been using those for years, primarily for miniatures. Given the issues that we face with them, I don't know that this stuff is really going to take off.
I got 4D because it was 50% off last Christmas season and it is definitely not worth the regular price of $200+. It is very firm and heavy. The lightweight primeknit upper with a heavy midsole felt weird while walking or jogging.
100% agree! but it's not just some of the Adidas models. Other brands like Nike, Puma, Asics, and even some brooks will combine these super lightweight uppers with a "heavier" midsole. Now the midsoles usually aren't actually "heavy" they just feel it when compared to the upper. I'd rather have a shoe that is slightly heavier but provides a more balanced feel on my foot.
Might not be Super helpful, but I find if I film a portion of my video while sitting on the floor, the cat(s) are guaranteed to make an appearance. Haha
I bought their previous 3D printed shoes; they are alrite and have been holding up fine. Good quality. Firmer than I expected, but fine. The heal was a bit wedged up, I guess to show off the 3D printed matrix more, and I'm not sure I care for that. Price needs to come down, as I'd probably prefer to wear some of their high end foam shoes instead still, but these do have a more modern look.
My job is to design and 3D print dentures in a dental lab, and Carbon is a big name in that space! I work with Asiga printers because you can actually buy them, whereas Carbon printers are only available for lease. That's right, you pay by the month or by time spent in operation, no option to buy outright. The technology is amazing, however the promotional material shows product rising out of the resin pool smoothly. But in truth, there is an "up and down" motion repeated thousands of times (one for each layer printed). Carbon has the speed print down, but depending on the type of resin used and the thickness of the printed layer, prints can take 8-10 hours or more.
I imagine that this tech won't be utilized so much in footwear, but in other areas. I think all mattresses will eventually be made out of this material. Because if it has the same level of comfort as foam, but doesn't sink in, and always springs right back, it would be like having the comfort of a memory foam mattress, with the structuralism of an innerspring mattress. But unlike an innerspring, it won't crush over time (maybe?), and it will be much more lightweight. I think the weight alone will be the selling point. Because both foam and innerspring mattresses are quite heavy and cumbersome to get a mattress cover on them. And it's a chore I absolutely hate, when I have to change the mattress protector. With this, it would be so much easier.
What do you think of those “the captain” boots? Idk if you have already reviewed them, but they are supposed to be very hefty yet stylish. Running at Around 200$, I’m curious what you think
I don't understand why you only see bouncy as better. I think it's a good test that gives informative data, but I think thinking one side of the result is better than the other necessarily. For me personally, I would prioritize impact protection over springy responsiveness. Some people prioritize my health, safety, and comfort over a track time.
This particular Toaster is awesomely cool! 😻 As for the 4D Fusio, its open-lattice-structure midsole will eventually collect dirt, pebbles/sand, dry grass, etc. which would be impossible to clean out.
@7:35 Test to see if "stuff gets actually gets stuck in mid sole" IT DOES, so your response "Ya just gotta be careful...." They're running shoes FFS. It's a design flaw!!!! Don't throw responsibility for this flaw back at the consumer! Maybe if we never wore our running shoes outside then they would never get dirty and the mid sole would never get clogged with dirt. $200 for a shoe that sucks!
Soon as i saw it was DLP/DLS/resin printed im out. Not gonna be as strong as other methods. with the correct filament, nozzle and an FDM printer it would be more then 30 pounds for sure. You gotta realize resin isnt made for strength. Its made for detail so people use them to make figurines. ALso, post processing resin vs FDM is hell. FDM requires little to no post processing. Resin needs a bath of alcohol and UV blast to cure the rest. All of those thickness variations can easily be done with FDM and you cant do multiple materials at once with resin, but you can with FDM. so you could print an elastic sole with a built in composite/carbon fiber toe and a TPU based upper and PETG/carbon fiber eyelets. you cant do any of that with Resin. This is coming from someone who has been printing since 2010 and has owned several printers and has printed shoes long before it was cool.
I was so excited for the original Futurecraft 4Ds but the original release was so botched. They’re were SO limited (beyond Nike limited releases) that they’re resale prices couldn’t be justified. By the time Adidas finally figured out production, the interest was gone. Plus they started releasing a bunch of ugly, uninspired designs.
I remember Adidas shoes from the 1970's when I first started running track in high school. Adidas quality was unmatched. Puma, Brooks, Nike, converse, Onitsuka Tiger, which was renamed ASICS, and all the other pretenders were a step behind. Sometime in the early 2000's, I bought an adidas running shoe which literally disintegrated while I worn them. First the uppers ripped then the sole wore out rapidly. They were clearly designed with the shitty and unscrupulous planned obsolescense. And the price was obscene. And the final insult was the salesman telling me that I would have to replace the shoe every 5 to 6 weeks.
3D printing expert here. Your description of the differences between "standard" 3D printing and "digital light synthesis" (which is only a marketing term really) was sadly wrong. Both methods are fundamentally the same - creating 3D objects layer-by-layer with the same flaws and disadvantages. Extruder printers can also print with 0,05 mm layer thickness (albeit resin printers can achieve even 0,01 mm). Resin printing is also created layer-by-layer, some do the whole layer at once, and some do the layers gradually (basically the same as extruder printers). Resin printing can be much faster but could also be slower, it really depends on the shape and used technology. It's not easier for prototyping, it's the same. It's not stronger by default, it depends on the used materials. You can make super fragile resin prints and virtually indestructible extruded prints. Resin printing is generally much more deceptive to defects, one mistake in angle, supports, or gravity and not only the whole thing is ruined but often also the printer itself. The only truth is that resin printing produces cleaner-looking parts due to the thinner layer lines (but also can print at 0,1 mm). The funny thing is that resin printing is 80' technology, it's nothing new. It was the first 3D printing invented, extruder printing was only a derivative of it.
This 4D tech will only get credible and popular if it gets used and wins in a long distance marathon event by a top running athlete. For now it's a very expensive and somewhat heavy lifestyle shoes. Top tech but can't beat the likes of their own Lightstrike, Nike's ZoomX, Saucony's PWRRUN etc.
3-D printed shoes..-eh ok if ok for those who can justify the cost. Now a 3-D printed insole- made from a scan or imprint of a persons foot to match a favored shoe... that I'd spend $40-$80 per set. Now note I stand for nearly all 40 hours in my 4 day 10 hr shifts in my Jim Green ~African Rangers
Resin printing has existed for a long time, and it's become available in consumer printer's for some time now. They own you with their gimmick. It's not that impressive
I had a pair of pumas, like 15 years ago, that had a midsole made of cells like X, with a hole on the middle on the sole, one time I stepped on 💩, and it came out of the cells like fvcking Play-Doh 🤣🤣🤣🤣🤣 I don't remember the name, but the footprint looks like a horseshoe (if anybody knows what I'm talking about)
Wot is up with THAT CAT!!!!!!????????? it should get its own channel! its not of this world!!! just a camera strapped on its back so we can see where it is on livestream 24/7
Got a pair 6 months ago and for a full day on my feet i prefer these over my Ultraboost 21’s and Nike pegasus 39’s. Maybe it’s the firmness which is good for hours of weight on your feet. One thing I don’t like about them is the fit. Tts they are looong and loose, but half size down and the arch length is short 😅 so i constantly have to readjust my laces. The heel material also cuts into your skin. The shape is just weird, heavy too. But I can’t seem to understand why im drawn to them!
i like your videos but crude leather bro products are gross. Even mass market stuff is so much more refined and just better. like seriously. it's gross. overly thick. unfinished edges. no tapering. just vile. disgusting. Look at some Italian or French leather brands to see how it's done right.
You picked the absolute worst example of the “4D” shoes to discuss the idea. This is part of the Originals lifestyle range. The runner was released as part of the performance range. That skirt is worthless unless one counts squeaking as a positive. I owned several pairs of these shoes, and I never had an issue with anything lodged in the midsole. Water protrusion is the big drawback. It would to be paired to a Celermesh upper to allow water to quickly escape. adidas released a teaser with Strung tech. That is the future. It is nice for all day wear as it stands today. ✌🏽💙👟
It's like that vietnamese coffee, made of coffee beans pooped out by civets...it can only be done that way. Yeah, so what. In the end is it better/cheaper/prettier? Not really. Don't care. And I'm a product designer.
I own a 3D printing shop and I’d like to shine some light on the technology used. The technology they use is called Stereolithography and it is actually old it was originally designed in the 80s and all it is basically is UV or Laser Cured resin. FDM was designed a bit later, and although you might see layer lines with FDM more, you also have layer lines in stereolithography. The downside of FDM is yes the layer lines have weak spots on the orientation it prints at, but you have much more material choice flexibility. the downside of Stereolithography is it is very UV sensitive and generally not very strong. The quality in visuals is there but not in its strength. Industrial resins and better but either way, it’s funny when I see every brand with their own fancy naming for the tech. DLS is advertising itself to add an extra step to the process but I think really it’s all the same stuff. Very advanced overall technology but both have use cases.
My wife is an avid runner and she started having knee problems with these shoes. Bought a pair of Hoka and she’s doing well now. Not saying hoka is better than any other shoe, just saying she stopped having bad aches and pains.
Here's a sales pitch for Adidas: "Our shoes are not as crappy as Nike's"
Eh. Nike makes three good shoe models for every good adidas.
Nike's marketing team is so good they'd just get Drake to drop an Adidas diss track

“But still made by children in sweatshops”
@@Hanitcal69 Chinese proverb. "Our kids work in sweatshops making shoes to sell while American kids steal them and work on their gender identification." Got it.
Great video!! As a sneakerhead and someone who own the Adidas 4DFWD, I can say it is worth every penny. This specific model has Adidas’s and Carbon’s newer 4D midsole tech which has a different structure than the first 4D midsoles from Adidas, which I believe is also used in those 4D Fusio. Basically, the newer 4D tech is more springy (making it more suitable for their running shoes, hence why its in the 4D FWD), and is actually more comfortable than the original version. I love my pair of 4D FWD.
Yes, things do get stuck inside the midsole, so you don’t wanna put it through dirt or mud. It is very much a city walking/running shoe. But, it’s a small price to pay for tech that’s really pushing the boundaries, and a still comfortable shoe.
Thank you very much for the analysis.
I have a small note that will help you analyze your shoes in more detail after the cut.
You need to make cooling for the cutting machine. This is necessary because during cutting the temperature of the cutting blade increases and it thermally deforms the cut sites for materials made from materials with a low melting point.
Thank you !
i have s few pairs of the OG 4d -- and a pair of the 4DFWD. RE: 4D - if you're looking for springy bounce, look elsewhere. But if you want firm, supportive, all-day comfort, they're amazing. RE: 4DFWD - The FWD stands for 'Forward" -- and there's a propulsive springiness you can feel - especially if you've spent time in the regular 4D. It's 100% true that dirt and dust get trapped in the midsole. You could probably soak them in a shallow pan, but I've never tried it. All in all, it's great tech - and I think we'll see a lot more... as soon as someone can scale it.
The colour on these are wild. The Screaming Yellow Zonkers of shoes. (If anyone’s old enough to remember those)
Thanks for doing the vid! Great to see your take on them. I'm a big 4D fan and own several pairs.
This original 4D sole is a lot firmer than the new generation 4DFWD and it's "squish" factor is totally different league. As an experiment, I actually soaked a brand new pair of 4DFWDs in boiling water for a few hours and it totally changed the softness of the 4DFWD structure. I use it for casual walking and it is by far the best in comfort for all day, everyday wear!
What I prefer with these, is the hold up over a year, these haven’t worn out at all. They still feel like the first week of wearing them
man imagine if you could just draw a heat map of the shoe's sole and have it made just like you drew it, that would be sickkkk.
The purpose of the 4D 3D-printed structure is for forward energy return, not vertical.
As an owner of the original Futurecraft 4d that's made in Germany, it's not as comfortable as the UB, but still the dopest shoe to this day.
That cat looks so cool! And I agree this new 3D printing method is amazing. I hope these companies use it wisely, I hope.
Love how every time he says "far from scientific" when these are the most scientific tests I've seen regarding sneakers without auditing R & D for every major sneaker brand

Ive been saying this so long it seems he won’t do it. Someone should do it I would sub so fast. Just got some high tops from Axel Arigato made in portugal out of calfskin I love them.
I agree, 3d printing the midsole is kinda neat, but without the customization it doesn't seem like it is really making the best use of the technology. I absolutely see a potential future, really could be done now at least to some extent, where you have a shoe store with just some samples and the equipment like treadmill for mocap, pressure plate and 3d scanner to measure various aspects of your feet and how you walk and run, then you pick an upper, customize that, and like 30-60 minutes later after all of that is fed into a computer, you have what should be the perfect shoe for you, at least as far as support and comfort are concerned.
Making 3D printed shoes on demand is going to require an expert in footwear manufacturing and 3D printing in-store at all times. I can see maybe a few rare specialty stores that can do this but these shoes would be incredibly expensive.
Resin 3D printing is also ultra-toxic, putting a resin machine in a consumer store probably wouldn’t meet safety guidelines.
"Like " for the cat 😂...and for you😅
Congratulations from Córdoba, andalusia, Spain
This particular shoe reminds me of the Nike Airmax 97
Future of footwear is customizable for your weight density
I have one pair of 4DFWD and its forward spring technology is noticeable when I run. it felt like something was pushing me forward when I first ran with this shoe.
Seeing a future where they can make a shoe just for you really isn't a stretch, and as somebody with ridiculous archs sounds great.
The fact that they even said "sneakerhead" in their marketing told me everything I needed to know about what kind of culture they were hoping to snag with this line. If they wanted to implement this technology meaningfully they would probably be hiding the lattice structure behind a wall to prevent the debris from entering the shoe and purely just provide interesting support. They wanted something visually striking to match their marketing standards for a large investment.
I hope the future where they integrate this tech into their standard styles of shoe is decent, but I personally put function on the same level as form.
Sneakerhead as in the culture of people who buy and love sneakers more than anybody else on earth. Seems like a pretty good group to go after to me 🤷
I think you're confusing sneakerheads with hypebeasts.
Didnt they use that special printing process to make the models for the action figures in Small Soldiers. Its been a while since i watched the scene but i recall it looking similar
The midsole reminds me of the airless wilson basket ball.
this is the result of the hype around 3D printing a few years ago. eventually i think you’re right; parts of shoes will be printed in or near the location you buy them. But i think that will come fr either a niche space or a smaller company first. These mega companies already have the supply chain in place, there’s no need to disrupt themselves…but a new player in the game who wants to be the Build-a-bear for shoes?! hell yes
4D Fusio is a great pair indoor workout shoe, best I have ever had. With bouncy midsole often you're sacrificing the ankle stability, and 4D Fusio hits the right balance for me. I have gotten the other pair of 220$ Adidas 4D shoes, which is a bit bouncier -- imo less great for training purpose. I sound like a blindsided advocate, but I really love my 4D Fusio
I recently purchased these shoes, acquiring them just yesterday. When comparing them to my previous pair which is Adidas Ultraboost, I've noticed some differences. The 'Fusio' shoes feel excessively hard and firm, making them less comfortable than I expected. Additionally, they seem unbendable, lacking the flexibility I prefer in footwear. Moreover, I've observed that the fabric near the heel area is overly stretchy, which inadvertently causes my foot to slip out easily while wearing them."
You should do nike air force vs bapestas next
Hi super cool videos :) two comments
1- historically DLS is the standard 3D printing is super old 🤯 not as FDM
2- as you said in your intro, the 3D network is designed to push the foot forward, did you try to test your rebound tests with an angle ? Like 30° this way you while be in the optimal direction for full rebound.
It's so cool to see how the videos evolved time :) take care.
Last question, I'm a great fan of Alexander McQueen sneakers. By any chance, could you make a review one day ? I want to know if it's real leather or coated one.
I have very wide feet with a high arch. It is almost impossible for me to purchase a pair of comfortable shoe. I have been talking about the future of 3D custom made shoes for years. The advantage of 3D is the CUSTOM fit. Shoe manufacturers should offer the option of custom fitted shoes to all 3D shoes.
The reason the ball drop test didn’t work is probably because you dropped it on the heel, where the lattice is spread more apart, absorbing the energy. When you run, you don’t heel strike so if you were to cut off the top of the shoe and drop the ball at the front, it would most likely bounce around the same height as the other mid soles
Can you you do a video on the Satorisan please? Love your videos!
I want to see a review for the north face base camp mule.
Definitely a new construction method for shoes. Not necessarily a good one.
I know this sounds weird but I would be curious as to how these shoes would hold up after being in the sun for a few days/weeks. These resins they use cure with specific wavelengths of light, and also degrade from exposure to light, so it's possible these shoes could crumble eventually if left in the wrong conditions.
To be fair, that's pretty much what would happen to a large majority of running shoes. Depending on where you live.
As someone who loves sneakers and has been trying to max out on comfy tech AND someone who really likes Adidas - I think these shoes are just a great proof-of-concept right now. In practical purposes, I’d rather just go with an Ultraboost because the advantage isn’t significant. The biggest downside for me for this tech is that it has holes! And no matter how careful you are, stuff will go inside them. Imagine spiders crawling up in there and nesting, for example. The best way to make this tech more practical for daily use is to encase the outsole like they encase the Boost in Yeezy 350s. They did it half-way here, but I think that would be the real deal-sealer, and that would finally make the conversation about its comfort over other tech. Right now it has a new sort of impractical disadvantage that other outsoles don’t.
There goes that cat, I missed him...! 😊
I really enjoy your work my man, but I get distracted often by you cat, that seems to be looking at you like you're 'Looney' or something; thinking its just you two in the room...! 😆
But he seem's to be loyal & supportive in your issues...! 😄Am I the only one that has mentioned that...? 🤔
Could you make a video on guidi
I just purchased a pair of Adidas Adifom Q. Any chance of you reviewing them ?
can you do a video about the lowa renegade gtx mid? its a hiking boot
Well yeah it’s cool tech but on the other hand once it’s established and the printing machines are ready to go… it’s really just light curing a polymer so….
Very easy to mass produce and just a different way to a mold.
All resin printers use light; the difference between Carbon and other resin, it's called CLIP (Continuous Liquid Interface Production) which has a membrane that allows printing in less than 25% of the time of regular resin/FDM and the product is printed at the *molecular* level so the finished unit has the same structural strength as the original material so there is no weak points or characteristic printing issues like delamination or needing to smooth parts - parts come out of CLIP ready to use.
Is there any resin availlable which is similar to the one addidas uses?
Let’s see you cut an Ozweego I see everyone wearing them and they use 2 types of foams Adiprene and Adiprene + (or do they?) 🤔
im happy cause kitty.
You did Call them Nike there for a second
Why does that cat look so damn angry 😾
Can not wait to clean the dirt from these.
This shoe uses the original 4D midsole tech which does not have very advanced forward spring technology. The more modern Midsole with what adidas call the 'Bowtie Pattern" can be found on the 4DFWD are a massive generational leap in comfort. I've owned both styles and the newer tech is simply superior in every way. Great Video!
Thank you for the information! I hope Rose Anvil does a video about that one!
The lattice structure and the material used in the 4DFWD is so cool how it launches you forward! I just got some XPLR Boost and for a big guy like me they are so comfortable.
It seems to me that he bought the ones on sale. Those Fusio are around 70 bucks now
Agreed but ultra 4wd is super narrow
I actually think the 4DFWD is more squishy anyway
I had some 4d shoes, they are pretty cool and are also pretty comfy in a firm kind of way. The only problem is (like you said) the holes get stuff stuck in them super easy, including a worm which I saw coming out of them once!
I hear you on the firmness, but I haven't had any issues with the holes yet. I don't take them into the dirt or mud though; just to the gym or store.
I bet that worm had an interesting time
Came for the shoe, stayed for the cat. Quick thing on 3D printing: stereolithography (SLA) printing has actually been around for decades, and you can buy a SLA (or MSLA) printer for really cheap. Carbon printers have some extra magic but even the cheap Elegoo printers work great for the home hobbyist.
Edit: I mentioned this in another thread but I’ll add it here: watching a physical thing get pulled out of a vat of goo using nothing more than light is like magic. It’s been around a long time but it’s still absolutely amazing.
Word. I remember seeing stereolithography footage on science & engineering programs like NOVA when i was a kid; at least the early-90's, maybe earlier. Was *very* sci-fi at the time, seeing a skull or whatever emerge from the goo.
For a while, before common man got a hang of it, the cheaper units were locked behind patents. At first, they weren't even on the markets, simply locked away. In theory, we could've had 3D printers back in the 80's, sure, not for Average Joe, but none of the tech that was required to get one running is new. And at that, back in the early 90's a few CNC mills were converted to use extruders to make precise casting blanks for machining plastic bits. Funny how that works, huh, old scrooges plopping their feathery arses on tech and locking it away for no good reason.
@@aserta with FDM printing, Stratasys got the key patents and built their business around them-they didn’t just sit on them. But I agree the 26 year duration of patents is waaaaay too long, and the giant wave of innovation that began in the 2010’s was because the Stratasys patents expired. Open-source companies like Prusa Research have pushed FDM technology ahead far more than Stratasys ever did. Patents should be good for 3-5 years, tops.
as an FYI, Carbon is not SLA technology, it is DLP. The processes are different and comparing an Elegoo or hobbyist printers to a Carbon machine is such a bad comparison you really shouldn't even compare them.
@@Fishbone8891 Carbon’s magic isn’t DLP; you can get DLP in hobby-grade printers these days. It doesn’t really matter if the UV light comes from a laser (SLA) a masked UV source (MSLA), the magic in Carbon printers is their management of oxygen. It allows them to move the curing away from the UV source so that the printer doesn’t do the raise/lower cycles after each layer. A traditional SLA/MSLA printer spends most of its time un-sticking the part from the UV source whereas a Carbon printer can just pull continuously-it’s much, much faster.
please do the 4DFWD shoes, its the renovation of the $D line from adidas
The idea of going to an Adidas store and getting a custom sole that fits me is very, very exciting. I hope that's something we see in this lifetime. If nothing else, it'll put some pressure on Dr. Scholls.
head office of Adidas: ‘we need to crush this doctor putting stuff in outlet shoes’
There's a fitness store my partner goes to in Prague which has a machine to measure her foot, how she runs, and puts weight on different areas of her foot, and makes a custom insole based on the measurements...
I have been through two pairs of 4D running shoes and am about to buy a third. I prefer them, firstly, because the midsole is super durable compared to Ultraboost, so I don't have to coddle them on runs.
The second thing is the FWD midsole is less about vertical rebound and much more about 'forward efficiency.' It's not as springy, but I find over a long run I become less fatigued with the help of the forward propulsion. And the targeted densities.
Third is, because I give these a light clean regularly, they stay much fresher than the white foam midsoles of other shoes. Foam midsoles stain really badly over time, so running warm, soapy water through these once a week makes them fresh for the life of the shoe.
And suprisingly great underfoot ventilation.

You do *not* end up with a stronger, better product than with extrusion printing.
Hoffman Tactical has done extensive testing on 3d printed materials and liquid resin printed materials are consistently less durable than extruded materials.
The only benefits are layer adhesion and smoother finish.
The materials themselves are less durable by a large margin, and they are much more expensive to produce.
Could you please cut in half a pair of Zellerfelds they're also a 3D printing company but the diffrence between their footwear is that they are 100% made in a 3D printer and (supposedly) made out recylebale materials i would have been very intrested to see your dissection and review of it
Btw loving your videos ;)
I remember when Adidas launched this product in 2015. Their was hype they would have these 3d prints in store to custom make shoes within 5 years. I don’t think they will not make custom shoes any time soon.
Vivobarefoot and Pangia have already started making custom shoes
@@Winford.Studios that's like saying that custom shoes have been a thing since the invention of shoes
@@Winford.Studios Vivo is currently a trial run and they need to accept you as “pioneer”. While Pangaia’s has better “availability” but their are still two issue. The whole sneaker is 3d printed which I would imagine affect comfort and the quoted availabilily for shipping time is anywhere from late October to mid January.
I have a feeling that someday soon we will come full circle with shoe “tech” people will just be back in anatomical shoes made of natural materials
I hope this takes place soon, because there's an obsession for soles tech but the upper part of the shoes are becoming like clowns' shoes (narrow and pointing upwards).
I don't think your performance tests are really able to capture the performance characteristics of this shoe. As you can see in the footage from Adam Savage that you linked, this structure rebounds at a particular angle, not evenly in all directions like a foam. The ball and bar drop tests can work to test rebound of foam, but if this material rebounds at an angle, you're only going to get a reduced percentage of rebound in a test where the impact is coming perpendicular to the material. I'm not sure how you could really adjust this sort of garage-science test to test for the angular rebound these lattices are meant to maximize, but I'd be really interested to see how they compare to foams for rebound in the angles that matter when worn.
Adam Savage has a video on his Tested channel where he visits one of Carbon's labs and talks to some of the engineers about their tech and other fun stuff. Definitely worth a look!
I think the newesr is 4DFwd2. I always wanted to try these 3d printed midsole and i just got myself for 100usd. This video came in clutch before i get mine tomorrow
I wonder if they will eventually be able to print them to fix posture. Like gradually changing the shape like invisaline braces to slowly fix a incorrect joint or something. Maybe even correct bunions over time.
Aww, Toaster! 😍 Wait, what was the video about? 👀😁
Have had several pairs, best so far is the ultra4fwd's-a lot more 'bounce' than the original 4D's, and the upper on the ultras is much more comfortable. 4D is nowhere as squishy underfoot as ultraboost, and feels heaver underfoot. More of a lifestyle shoe, I go with Hoka's for a run.
I don’t understand this fascination with squishy athletic shoes. It’s backwards thinking. The squishier the shoe, the lazier the muscles in the feet become. Also, injury becomes more concerning due to the instability of squishy. Yet all RUclips athletic footwear reviews measure the validity of a shoe mostly based on how squishy it is. 🙄
Being a die-hard boost head Ultraboost was something I wore exclusively. They are confortable, stylish, and versatile. However as I get older I find, to my dismay, the amazing softness of the midsole is giving me foot fatigue on the top of my arches and also the big toes area. 4D midsoles alleviates all of that. They have a firm give when you first step into a new pair, but it also provides a sensation of "embracing" your foot. They provide all day comfort and support without feeling mush-y. And trust me, they get more comfortable as you wear them in.
So far I have had zero problem with materials being stuck in the midsoles in all my 4D sneakers. The price is really stiff yes, but they are definitely worth it when they go on sale.
Congrats, you've figured out soft shoes ruin your feet
@@placeholder3863 No that's not the case at all. It's about finding the right cushion setup for your age, and for the right occasions. I wore boost predominantly for the longest time, and they were the bee's knees. But as I'm over 40 now I need something firmer if I were to be on my feet all day. Plush cushioning is still great when I go for a walk or a jog.
just saying here, I got the micro adjust belt and it's great honestly. really nice leather and measured to fit is right on. he didn't pay me, but im glad i got it. if you haven't had high quality leather before, it's very cool!
The only thing that i really hate about the recent trend is the bulky larger heel. That it goes further of where the heel actually ends
I do not find that aesthetically pleasing either. It's ugly, sort of in the way a Toyota Prius is ugly ... just mal-proportioned.
@@cacogenicist Totally! The rest is actually innovative and cool.
I call the "elephant foot".
Imagine all the gunk accumulating overtime in there xD Prime housing for bacteria and insects 👍🏻
Adidas needs to make a solid outline models asap.
So they use a resin printer to make them.
We've been using those for years, primarily for miniatures. Given the issues that we face with them, I don't know that this stuff is really going to take off.
The shoe you are testing doesn’t got the lattice structure wich propels you forward that would be the 4DFWD
I think you need to try the 4DFWD2
I'm really excited to see a review of the Yeezy 500! Can't wait to hear your thoughts on them!
I got 4D because it was 50% off last Christmas season and it is definitely not worth the regular price of $200+. It is very firm and heavy. The lightweight primeknit upper with a heavy midsole felt weird while walking or jogging.
100% agree! but it's not just some of the Adidas models. Other brands like Nike, Puma, Asics, and even some brooks will combine these super lightweight uppers with a "heavier" midsole. Now the midsoles usually aren't actually "heavy" they just feel it when compared to the upper. I'd rather have a shoe that is slightly heavier but provides a more balanced feel on my foot.
You need to try a Saucony Tempus. Lightweight, bouncy, and supportive.
Might not be Super helpful, but I find if I film a portion of my video while sitting on the floor, the cat(s) are guaranteed to make an appearance. Haha
The 4d midsole is noce. Got a pair thinking it be a gimmick but i love em
I bought their previous 3D printed shoes; they are alrite and have been holding up fine. Good quality. Firmer than I expected, but fine. The heal was a bit wedged up, I guess to show off the 3D printed matrix more, and I'm not sure I care for that. Price needs to come down, as I'd probably prefer to wear some of their high end foam shoes instead still, but these do have a more modern look.
i didn't know shoe content would be so interesting.
My job is to design and 3D print dentures in a dental lab, and Carbon is a big name in that space! I work with Asiga printers because you can actually buy them, whereas Carbon printers are only available for lease. That's right, you pay by the month or by time spent in operation, no option to buy outright. The technology is amazing, however the promotional material shows product rising out of the resin pool smoothly. But in truth, there is an "up and down" motion repeated thousands of times (one for each layer printed). Carbon has the speed print down, but depending on the type of resin used and the thickness of the printed layer, prints can take 8-10 hours or more.
I imagine that this tech won't be utilized so much in footwear, but in other areas. I think all mattresses will eventually be made out of this material. Because if it has the same level of comfort as foam, but doesn't sink in, and always springs right back, it would be like having the comfort of a memory foam mattress, with the structuralism of an innerspring mattress. But unlike an innerspring, it won't crush over time (maybe?), and it will be much more lightweight. I think the weight alone will be the selling point. Because both foam and innerspring mattresses are quite heavy and cumbersome to get a mattress cover on them. And it's a chore I absolutely hate, when I have to change the mattress protector. With this, it would be so much easier.
Latex is way better.
Damn.. that's an incredibly ugly shoe!
You sir have no taste
What do you think of those “the captain” boots? Idk if you have already reviewed them, but they are supposed to be very hefty yet stylish. Running at Around 200$, I’m curious what you think
I don't understand why you only see bouncy as better. I think it's a good test that gives informative data, but I think thinking one side of the result is better than the other necessarily. For me personally, I would prioritize impact protection over springy responsiveness. Some people prioritize my health, safety, and comfort over a track time.
i mean if you don’t consider bounce a plus then you can simply ignore that point for your buying justifications
Wait, I could help kill the toxic shoe culture by getting 3D printed shoes? Great point. I want 3D printed shoes NOW!
This particular Toaster is awesomely cool! 😻
As for the 4D Fusio, its open-lattice-structure midsole will eventually collect dirt, pebbles/sand, dry grass, etc. which would be impossible to clean out.
Exactly what I was thinking. As to how that was not though of in foresight, who knows...
@7:35 Test to see if "stuff gets actually gets stuck in mid sole" IT DOES, so your response "Ya just gotta be careful...."
They're running shoes FFS. It's a design flaw!!!! Don't throw responsibility for this flaw back at the consumer! Maybe if we never wore our running shoes outside then they would never get dirty and the mid sole would never get clogged with dirt. $200 for a shoe that sucks!
Soon as i saw it was DLP/DLS/resin printed im out. Not gonna be as strong as other methods. with the correct filament, nozzle and an FDM printer it would be more then 30 pounds for sure. You gotta realize resin isnt made for strength. Its made for detail so people use them to make figurines. ALso, post processing resin vs FDM is hell. FDM requires little to no post processing. Resin needs a bath of alcohol and UV blast to cure the rest.
All of those thickness variations can easily be done with FDM and you cant do multiple materials at once with resin, but you can with FDM. so you could print an elastic sole with a built in composite/carbon fiber toe and a TPU based upper and PETG/carbon fiber eyelets. you cant do any of that with Resin.
This is coming from someone who has been printing since 2010 and has owned several printers and has printed shoes long before it was cool.
I was so excited for the original Futurecraft 4Ds but the original release was so botched. They’re were SO limited (beyond Nike limited releases) that they’re resale prices couldn’t be justified. By the time Adidas finally figured out production, the interest was gone. Plus they started releasing a bunch of ugly, uninspired designs.
I remember Adidas shoes from the 1970's when I first started running track in high school. Adidas quality was unmatched. Puma, Brooks, Nike, converse, Onitsuka Tiger, which was renamed ASICS, and all the other pretenders were a step behind.
Sometime in the early 2000's, I bought an adidas running shoe which literally disintegrated while I worn them. First the uppers ripped then the sole wore out rapidly. They were clearly designed with the shitty and unscrupulous planned obsolescense. And the price was obscene. And the final insult was the salesman telling me that I would have to replace the shoe every 5 to 6 weeks.
Looks like shhhhhhhhhhh
3D printing expert here. Your description of the differences between "standard" 3D printing and "digital light synthesis" (which is only a marketing term really) was sadly wrong. Both methods are fundamentally the same - creating 3D objects layer-by-layer with the same flaws and disadvantages.
Extruder printers can also print with 0,05 mm layer thickness (albeit resin printers can achieve even 0,01 mm).
Resin printing is also created layer-by-layer, some do the whole layer at once, and some do the layers gradually (basically the same as extruder printers).
Resin printing can be much faster but could also be slower, it really depends on the shape and used technology.
It's not easier for prototyping, it's the same.
It's not stronger by default, it depends on the used materials. You can make super fragile resin prints and virtually indestructible extruded prints.
Resin printing is generally much more deceptive to defects, one mistake in angle, supports, or gravity and not only the whole thing is ruined but often also the printer itself.
The only truth is that resin printing produces cleaner-looking parts due to the thinner layer lines (but also can print at 0,1 mm).
The funny thing is that resin printing is 80' technology, it's nothing new. It was the first 3D printing invented, extruder printing was only a derivative of it.
This 4D tech will only get credible and popular if it gets used and wins in a long distance marathon event by a top running athlete.
For now it's a very expensive and somewhat heavy lifestyle shoes. Top tech but can't beat the likes of their own Lightstrike, Nike's ZoomX, Saucony's PWRRUN etc.
3-D printed shoes..-eh ok if ok for those who can justify the cost. Now a 3-D printed insole- made from a scan or imprint of a persons foot to match a favored shoe... that I'd spend $40-$80 per set. Now note I stand for nearly all 40 hours in my 4 day 10 hr shifts in my Jim Green ~African Rangers
Resin printing has existed for a long time, and it's become available in consumer printer's for some time now. They own you with their gimmick. It's not that impressive
I had a pair of pumas, like 15 years ago, that had a midsole made of cells like X, with a hole on the middle on the sole, one time I stepped on 💩, and it came out of the cells like fvcking Play-Doh 🤣🤣🤣🤣🤣 I don't remember the name, but the footprint looks like a horseshoe (if anybody knows what I'm talking about)
Wot is up with THAT CAT!!!!!!????????? it should get its own channel! its not of this world!!! just a camera strapped on its back so we can see where it is on livestream 24/7
Got a pair 6 months ago and for a full day on my feet i prefer these over my Ultraboost 21’s and Nike pegasus 39’s. Maybe it’s the firmness which is good for hours of weight on your feet.
One thing I don’t like about them is the fit. Tts they are looong and loose, but half size down and the arch length is short 😅 so i constantly have to readjust my laces. The heel material also cuts into your skin. The shape is just weird, heavy too. But I can’t seem to understand why im drawn to them!
i like your videos but crude leather bro products are gross. Even mass market stuff is so much more refined and just better. like seriously. it's gross. overly thick. unfinished edges. no tapering. just vile. disgusting. Look at some Italian or French leather brands to see how it's done right.
Since Adidas doesn't partner with Kanye anymore they might want to approach MKBHD. Looks like they can do better for 200$ than his brand.
You picked the absolute worst example of the “4D” shoes to discuss the idea. This is part of the Originals lifestyle range. The runner was released as part of the performance range.
That skirt is worthless unless one counts squeaking as a positive.
I owned several pairs of these shoes, and I never had an issue with anything lodged in the midsole. Water protrusion is the big drawback. It would to be paired to a Celermesh upper to allow water to quickly escape. adidas released a teaser with Strung tech. That is the future.
It is nice for all day wear as it stands today.
✌🏽💙👟
It's like that vietnamese coffee, made of coffee beans pooped out by civets...it can only be done that way. Yeah, so what. In the end is it better/cheaper/prettier? Not really. Don't care. And I'm a product designer.
I own a 3D printing shop and I’d like to shine some light on the technology used.
The technology they use is called Stereolithography and it is actually old it was originally designed in the 80s and all it is basically is UV or Laser Cured resin.
FDM was designed a bit later, and although you might see layer lines with FDM more, you also have layer lines in stereolithography.
The downside of FDM is yes the layer lines have weak spots on the orientation it prints at, but you have much more material choice flexibility.
the downside of Stereolithography is it is very UV sensitive and generally not very strong. The quality in visuals is there but not in its strength.
Industrial resins and better but either way, it’s funny when I see every brand with their own fancy naming for the tech.
DLS is advertising itself to add an extra step to the process but I think really it’s all the same stuff. Very advanced overall technology but both have use cases.
My wife is an avid runner and she started having knee problems with these shoes. Bought a pair of Hoka and she’s doing well now. Not saying hoka is better than any other shoe, just saying she stopped having bad aches and pains.
