Joel! DUDE! Thank you for giving my fused footwear a try, it it's super satisfying to see the guy who inspired part of my journey, finally wearing them! You're awesome!
What all of these miss is the real benefit of 3D printed shoes: one designed specifically for your foot shape. That should be the goal, a way to scan a foot, and print a shoe for that specific foot. Would really help people with foot problems.
Totally agree. I was going to say the same thing. My local athletic shoe store actually does a full 3D scan of your feet to exact scale and they use that to properly fit shoes to you. They even send the completed 3D scan to you to see all the dimensions and such. Turns out that my feet are actually slightly different dimensions. They look the same to the naked eye, but the scanner picks up the exact dimensions. There's no reason, we couldn't then send these scans to the shoe manufacturer and have them create the shoe around our actual feet. That would be amazing!
in the new balance stores they do that but they get as close as possible but will fully tailor a shoe to your foot if you custom order it in store but its not 3d printed which honestly is just cool
What kind of testing are you actually doing? You just glossed over the FUSE shoes and showed a short clip of you shuffling about on a smooth floor. You didn't even mention the material.
It would be nice if there was a 3d printed shoe project that could actually be made at home that was modular, repairable, customizable and could try to off set the enormous amount of wasteful fashion from poorly quality shoes made from exploited labor. Even if it was a mix of traditional and 3d, if it could be done at home that could be actually useful. I wear through shoes regularly, kind of tired of giving money to companies that intentionally make shoes that will fail. Its not the most complicated product, I look forward to seeing more shoe content
IMHO it is more of a filament issue than design. The TPU that we can typically print is still to stiff and hard to walk in all day. The Dutch gave up on wearing wooden shoe...lol.
@@Davids3DProjects Actually wooden clogs are fairly comfortable when they're made to your foot because all points of your sole is supported. And the wood will mould itself overtime through use, making it fit even better. The main reason they're not common is because custom handmade wooden shoes are really expensive compared to mass produced sneakers.
@@JSZ69420 the shoes on those shoes will be in everyone's organs and bloodstream within a year as well as the soles would be so worn down that you'll need a new pair already so you can start the micro plastic factory all over again. I legitimately think EVA foam soles need to be banned.

@@thedudeamongmengs2051 after looking it up I do not agree, because the information is boggled. Rubber is not a plastic. It is a polymer and an elastimer (sp?) but is not a plastic. But after searching do car tires produce micro plastics and stuff like that it says the rubber particles that come from car tires are considered micro plastics only because of size and composition. So, I do not agree that rubber is a micro plastic because it isn't plastic. They can call it a micro polymer if they want, lol. Regardless, a car tire lasts infinitely longer than any EVA foam sole which if your actually a runner can be worn through within a few months compared to a regular pair of shoes with RUBBER soles which will last many many years.
Joel!! I 3d printed my own boots! (add a micro-controller and LEDs as well). I am actually coming to Seattle Jun 1-8 for a conference... I'd love to show you my 3d printed boots if you're around! Sent you a message in discord as well.
I occasionally suffer from gout. Being able to customise some sort of crocks would be amazing. Normally people have issues with the big toe, so you could have the sole the sort of falls away and adds extra room.
Adidas 4d look awesome BUT that big toe hole is a massive issue. Also we’re wildly uncomfortable for me to wear when running. But look really dang cool
I tried the trail shoes (Ultras) and they are basically socks with a small pad underneath. Horrible design, do not get those. Twisted my ankle while doing a hiking test.
@3D Printing Nerd Joel I love the real review of them and the idea behind 3D printed shoes. My only question is how long did it take to wear them out? If they wear out on 6mo or a year that is about what I get out of traditionally manufactured shoes. The design alone would be well worth it as long as they can make them last a decent amount of time.
Amazing stuff! I see that others brought up the idea of scanning the foot to make a real custom-fit shoe. I'm pretty sure some bright person is doing that right now! On a different note: I see that PCBWay is still a sponsor, and it is a company I have used to make a number of prototype PCBs over that last several years. Very easy to work with, fast service, and good quality. All in all, a great company to have as a sponsor!
Hey Joel! Can you elaborate a little bit on what features you want in a utility shoe, and in what way the Zellerfelds fall short in that respect? I'm whipping up some trail runners right now, but can adapt to whatever geometries or features needed.
Hiking shoes is a great idea - you spend so much time in them that fit and comfort are incredibly important, but also traction, breathability, and water resistance are important factors. That will be a tricky development task.
Would be cool to see 3D printing advance to a level where prints could be precise as threads in fabric. Creating fine mesh for breathable, wearable clothing would be crazy! Great video!
I have a pair of addidas 4ds worked in a warehouse walked in them regularly and haven't had any falling apart issues and you didn't mention how insanely comfortable they are.
FYI you can use resin printer to print flexable rubber now. It may be possible to 3d print on a resin printer a shoe without layer lines. That said it would need to be a large format printer, probably not a hobby grade machine just based on the size requirement. But you can get a rubber like consistency UV resin now, I just got some and am surprised how well it can actually work.
are 3d printed products from flexible filament disintegrate and falls apart like PU sole of a shoes after sometime from humid in the air? Since both of them suffer the same issue which is hydrolysis.
What a fun review of the latest in 3D printed footwear! Wholeheartedly agree on assessment of Adidas/Carbon3D shoes. Having tried multiple pairs and run a few hundred miles in them the 3D printed midsole has held up perfectly but the traditional fabrics failed far too soon. Hopefully Adidas figures this out and the tech only gets better because from a shock absorption / comfort standpoint they're some of my favorite shoes. Just don't try to move around in them too much!
I think it is an excellent video, I hope to see in the future how this 3D technology merges with traditional manufacturing to generate more comfortable and durable products. At the end of your video it is clear that if done well it is possible to manufacture very comfortable footwear components.
It's funny that those socks are the exact hue of blue you're wearing, lol. Like, dude really did his research when gifting you those. 😂 Really interesting shoes, too. Yeah, after seeing all the shoes, Phillip definitely did the best. I've been watching 3d printed shoes since day 1, hoping someday it could break the mold on what's possible in creative design. And his shoes definitely has started on that path.
Excellent video!!!!!!!!!!! Could you tell us more about the materials in the different shoes? Here in Argentina there is not a wide range of flexible materials available
It would be interesting to see how the tpu material is stored before printing, the slicer settings and environment of the print area while printing to make such nice looking tpu products. Also, it would be nice to know which tpu manufacturer and hardness is used and if there is any post processing of the surfaces. It looks like these companies got it down to a science on how to print tpu, at least for shoes!
I only buy shoes based on my Euro or UK sizing, because it's based on centimeter measurements instead of some wild guess. It's crazy that in US I'm a size X in one brand, and an X-1 in another, and an X+1 in another. Even with half sizes in US you'd think they would at least get close, but no.
As a footwear retailer (this is my opinion, not those of my company) the crucial piece of information that is missing about the Adidas is the age of the shoes. Most shoes are only meant to last a year to 2 at best, (which matches the warranty most companies have) and the issues Joel showed are both very common failures in traditional running shoes, let alone 3d printed ones. I blow through running shoes made similarly, except for the 3d printing, in six months on average. Usually it’s my little toe searching for freedom through the fabric, sometimes the sole rips off, and ultimately 100% of the time the midsole gets crushed flat. The compression set of EVA midsoles over time is ultimately why they don’t warranty shoes past a couple of years, because EVA Foam just can’t handle sustained loads for that long. So the fact that the 3d printed midsole held up so well is actually a really cool positive development in creating more sustainable footwear. So ya, if they failed like this in a month or two then that is problematic, six months with the use described it makes sense why Adidas did a warranty replacement, and if a year plus well they’ve lived a good life, time to replace them, and Adidas found out Joel was a RUclipsr. I’m not trying to say that it was ok they failed, but given modern manufacturing techniques this was always the likely outcome, where weight and performance and comfort have taken priority over long term durability. So depending on how long before those problems occurred, it might be a little unfair to say that this model is a failure in context of how shoes are made and perform today.
Yeah, shoes are a scam and crap across the board these days. Most aren't even available in size 17-18 and if they are they're shaped all wrong, narrow toeboxes and such, and they usually don't last past a week. A few days in and the midsole just collapses to mush, the shoe feels like a lumpy slipper and my back and knees hurt from walking crooked. Bruh, shoes used to be good, but fashion over function and planned obsolesence made them shit aside from 'looking good', which i both don't really care about AND usually consider ugly or gaudy and cringe. Airwalks were the worst, i used to wear OG Airwalks and Vision Street Wear back in the day and both were solid and would last. It took skating big roof gaps to collapse the soles. Now Airwalks won't last a single park session, i blew through two pairs of Airwalks in a day and was skating barefoot by sunset. I wear pretty much only modded DC Courts these days, only shoe with a decent shape and big toebox i can find, even other DC models don't fit right. To keep them from collapsing i strip the guts out and bed the midsole airgaps with shoe goo, about 1.5 tubes per shoe and make the entire midsole solid. I also reinforced the inside seams with a layer and so far it's lasted about two months with no signs of collapsing. I just don't understand why they can't make a shoe like that from the factory, even as a paid upgrade. It costs me like an extra $30 of shoe goo and a few days to cure, i'd gladly pay an extra $40 or so for a legit solid shoe i don't have to disassemble and rebuild. But like FFS if you're selling a size 18 shoe you'd think they'd make it with a midsole that can bear the weight and forces of someone with size 18 feet. I'm not a 90lb wealking on waterskis, if i'm fasting and down to skin and bones i'm still around 220lb naked and more with all my gear and backpack and whanot. I heard Supras have a solid urethane midsole, i've always wanted some so bad but they don't make anything bigger than 14 IIRC. I originally got into 3d printing with the intention to make my own shoes back in around 2012-2013, i wanted to make molds so i can pour my own urethane midsole parts from quality materials instead of crap like EVA and mushy weak rubber and roll my own uppers, but i got distracted by all the other cool things it can do. Lately though i've been heavily into 3d printed moldmaking and have a lot of knowledge and experience that will help me out, so they might just be coming soon. But as for the directly 3d printed shoes, they all look like disposable gimmick fake swap meet louie yeezies, and yeezies are just glorified atrocious looking crocs in the first place. But then again that's pretty much all modern shoes. They just don't make 'em like they used to and nobody seems to remember back when they weren't all single use disposable fast fashion trash.
I think we are barely grazing the surface for sure. Hiking boots with spiky bottoms and stretchy latches that fix them firmly to your calf? 3D printed material interwoven into a traditional manufacturing fabric or tread to give it the ultimate bond? So many avenues.
What I am curious to see is a hybrid boot. I am into traditionally made leather boots, and have been learning construction methods, and I am interested in these. I wonder if a boot that utilizes a hybrid of something like a leather body with tpu at the flex points, (decreasing crease lines in certain areas) along with a tpu outsole and something like ABS or another stiff material for a shank and maybe parts of the lugs, among other things, could be viable.
Would be interesting if one of these lasts longer than a regular foam shoe with the different material. My shoes right now have a super big hole after a year. The foam shoes use just isn't very strong
…it’d be great to add 3d scanning to the mix so that the result was a shoe printed to order that was an exact fit, even for feet that were a bit wider, narrower higher etc
then you say humongous feet I have to ask what size you are? I am apparently a size 16 if I convert to us sizes. It just dawned on me that at some point 3D-printed shoes might be a thing for orthopaedics to help flat feet like myself
I have the catch 22 that "walking around a city at a quick pace" combined with "sitting still at a desk" is apparently how to utterly destroy shoes. The sole rips off, it gets punctured, the fabric rips, it gets bad and this tends to happen in 3-6 months... the catch 22 is that I've had this happen with budget shoes that cost $20 and more expensive shoes (the highest I went was $70...). I walk rain, shine, and snow, and remember asking Pooch about the Adidas and he said "it's fair weather footwear" and if I'm gonna spent 3 figures on shoes, I'm doing it once, not for fair weather + bad weather. I just can't bring myself to spend $100-$300 on shoes that could get destroyed in 3-6 months. I have a bunch of friends who tell me "it's higher quality, it will last longer" but after poking them they eventually get to "well, you'd probably destroy them in the same time but for a high quality shoe, you can get it repaired" and I had to bring in consumerism: $100 for 1 shoe every 3-6 months vs. $100 for 2-5 shoes that each can last 3-6 months... I'm gonna go with the cheaper shoe. All that is to get to the point: I'd love to 3D print my own shoes or the parts of the shoe that break... and right now, cost vs length of time it lasts is not there, and then seeing the quality issues with the Adidas just makes it harder still. One day.
As you have an XL as well as other big printers (like the Orange Storm Giga), I was expecting at least one or two pairs of self-printed shoes... even I have done it on my P1S. Which was, to be honest, not working really well as my feet are to big. The shoes finished, they fit - but they are not really nice.
I think we're overlooking a MASSIVE market edge here ... custom orthotics printed into the shoe. pair that with some more traditional shoe styling and you'd probably devastate the shoe industry. just about everyone has a CVS or similar somewhat near them with one of those dr scholl's foot scanners near the pharmacy. just send in a pic of the graph and here's your shoes.
Those first shoes look like they would really hurt if they accidentally hit your calves...anyone know what printer that is with the glowing red acrylic in the background??
As someone who is a Pedorthist by trade, some of the complaints about the Adidas you made are also on you as the user, specifically the upper ripping. Sizing is never accurate and consistent, that's why it's broken into a 'measure and fit' process. You should have a clearance from the longest foot from the longest toe to the end of the shoes but 15-20mm, more towards 20mm if you're a runner, this is due to flexion like when you flex a deck of cards, the direction you flex the cards, the inside cards will extend further than the outside cards, this is referred to as differential elongation, with shoes this is the foot and shoe, causing your toe to creep close to the end of the shoe. The shoes are also doffed and laced up, which suggests you're donning and doffing these without undoing the laces, which will create shear as your foot slides back an forth adding to the trauma to the upper.
All this ability to fix the issues with current footwear and none have addressed the heel height and shoe box width. Barefoot shoes are the way, and 3D printer creators can make a zero lift heel without issue yet still make these sweat inducing foot deformers.
I still think they should implement this with 3D scanners to get the perfect size for everyone's feet, it's the best process for it (and also not make narrow shoes with it which causes everyone's feet all kinds of problems..)
You’d want something a bit reinforced. Hand turning could easily be a PETG or ASA / ABS. However for driving it with a tool, you’d probably need CF Nylon.
@@3DPrintingNerd thank you, I have tried 100% infill PETG-CF and it mushroomed around the driving tool. Would you think something like ABS or ASA better? Or just go straight to CF Nylon?
I wanted to know how long they lasted and what you could print them on. If they only last a few days or you can't print them at home, they are not yet worth it.
All the shoes he's shown are daily wearable in my experience and opinion. And of course Joel has a pretty excellent track record oh honest and realistic reviews
I love the idea of 3d printing some parts of a shoe, but I would absolutely not wear one that was 100% printed, they all look clownish. Adidas are on the right track, it's too bad they cheaped out on the materials for the top, but that's a great concept.
@@harmless6813 You're on to something. In the case of Adidas the 3d printing was to create a complex pattern of gaps in the sole that made it springy. Looks like they printed that with rubber resin, which is likely way out of reach of most of us. If I were making my own shoe, I wouldn't take that route at all. I'd design a sole for my foot, add the traction pattern I want, then FDM print a sacrificial negative of it, and use it to cast a rubber positive. Voila - now I have a _real_ sole, one that is durable and flexible. Then I'd 3d print a jig to help me assemble an upper around, also shaped for my foot, and around that jig sew an actual upper out of nylon fabric, once again, like a _real_ shoe. Then glue the upper to the sole using whatever black magic glue sneaker makers use. This sounds like way more work than just sending a shoe STL to a printer, but I get a _real_ shoe out of it, and my 3d printer would help a huge part of the way. Shoe's are not made from a single thing, they're complex devices that have to be comfortable, durable and breathable. FWIW I use 3d printing to make design concepts for clients - clients want concepts in epoxy, silicon, cement, plaster etc, but 3d printing makes it so much easier to shape those media, and all my clients love how the 3d printing is helping them zero in on manufacturing questions from the very start of the process.
I'll say the shoes in the video need pull tabs at the back of the shoes since often times the shoes are just big enough to fit your foot and ankle and doesn't always have space for a finger to get in the shoe to get it on the foot right. Adidas needed to make some hook and press fit points on to their carbon fiber mid sole allowing the bottom sole and the traditional top part of the shoe, to better adhere to the carbon fiber mid sole since the different materials mean all pieces of the shoe aren't able to stick to each other for long time; were if the carbon fiber mid sole had hooks and pressure points for other parts of the shoe then the other parts of the shoe will stick to the carbon fiber mid sole over and over again throughout the daily use of the shoe since other parts of the shoe will keep on sticking to the carbon fiber mid sole better through the every day use of the shoe as they break in and set/stick to one other the person wearing the shoe moves around in them.
I'm happy you refer to the Adias shoes, not as 3d printed, but note they use a 3d printed component. The idea that if something has some percentage of 3d printed components, that people call them 3d printed is like nails on a chalkboard. e.g. - a computer case which is composed of about 75% 3d printed components, is not a 3d printed case.
Every industry does this. In the beef industry it’s “angus”. The definitions get skewed to mean something very different than the consumer is lead to believe. And most of the time, we consumers just go along with it because we don’t know any better.
8:10 they need cow hide uppers with carbon lowers rather than synthetic crap with carbon. Yeah - I know the carbon is synthetic too…buts it’s durable. Wait till they get plant based 3d printed material.
I feel like you should have addressed the price of the zellerfelds. They're almost $300. Way too expensive, especially since the filament cost is probably very low, and they aren't customized for the customer
There was a lot of r&d that went into the custom design and custom material. The product is still in a novelty stage and not willing to be widely adopted because it stands out too much, and a simple design change cannot fix that, the goofy design is fashion hiding a larger issue with 3D printed shoes preventing them from being more traditional, weather that is durability, comfort, breathability, or all of it. For these reasons the cost can be justified. Source: from personal experience try making some that fits all the requirements for regular mass adoption, the final 10% is very hard to solve.
After watching this, I'm of the opinion that someone needs to go back to the beginning of footwear and make a parametric sandle with a conpliant mechanism to strap them on. You know just enough shoe to provide a sole and maybe a bit of a toebox. But... least possible. This is just because, the less shoe there is, the fewer fail points it has.
You're not meant to wear the same pair everyday... You'll make 2 with 2 pairs. You need to let the shoe fibers de compress before wearing them again. 1 day will do.
Joel! DUDE! Thank you for giving my fused footwear a try, it it's super satisfying to see the guy who inspired part of my journey, finally wearing them! You're awesome!
So... Where can we get the STL?

Zellerfeld does that
I think maybe just an insole would be sufficient

The shoes can breathe they have holes near the foot.
Aren't most modern shoes all synthetic anyways?
Have you ever swabbed a regular shoe and grown it in culture? I have and I don't imagine it can be much worse, so long as there is airflow
And you can print more when you get there lol

Basically they are ice boots

Yeah, after seeing all the shoes, Phillip definitely did the best. I've been watching 3d printed shoes since day 1, hoping someday it could break the mold on what's possible in creative design. And his shoes definitely has started on that path.
what modeling software do you use?
I have been waiting for this day for a long time
They will ALWAYS find something to include in a shoe that they can use to time the failure point. They don't want to sell shoes that last forever.
Excellent video!!!!!!!!!!! Could you tell us more about the materials in the different shoes? Here in Argentina there is not a wide range of flexible materials available
It would be interesting to see how the tpu material is stored before printing, the slicer settings and environment of the print area while printing to make such nice looking tpu products. Also, it would be nice to know which tpu manufacturer and hardness is used and if there is any post processing of the surfaces. It looks like these companies got it down to a science on how to print tpu, at least for shoes!
I only buy shoes based on my Euro or UK sizing, because it's based on centimeter measurements instead of some wild guess. It's crazy that in US I'm a size X in one brand, and an X-1 in another, and an X+1 in another. Even with half sizes in US you'd think they would at least get close, but no.
Zellerfeld makes the most comfortable shoes in the world
As a footwear retailer (this is my opinion, not those of my company) the crucial piece of information that is missing about the Adidas is the age of the shoes. Most shoes are only meant to last a year to 2 at best, (which matches the warranty most companies have) and the issues Joel showed are both very common failures in traditional running shoes, let alone 3d printed ones. I blow through running shoes made similarly, except for the 3d printing, in six months on average. Usually it’s my little toe searching for freedom through the fabric, sometimes the sole rips off, and ultimately 100% of the time the midsole gets crushed flat. The compression set of EVA midsoles over time is ultimately why they don’t warranty shoes past a couple of years, because EVA Foam just can’t handle sustained loads for that long. So the fact that the 3d printed midsole held up so well is actually a really cool positive development in creating more sustainable footwear.
So ya, if they failed like this in a month or two then that is problematic, six months with the use described it makes sense why Adidas did a warranty replacement, and if a year plus well they’ve lived a good life, time to replace them, and Adidas found out Joel was a RUclipsr. I’m not trying to say that it was ok they failed, but given modern manufacturing techniques this was always the likely outcome, where weight and performance and comfort have taken priority over long term durability. So depending on how long before those problems occurred, it might be a little unfair to say that this model is a failure in context of how shoes are made and perform today.
Yeah, shoes are a scam and crap across the board these days. Most aren't even available in size 17-18 and if they are they're shaped all wrong, narrow toeboxes and such, and they usually don't last past a week. A few days in and the midsole just collapses to mush, the shoe feels like a lumpy slipper and my back and knees hurt from walking crooked.
Bruh, shoes used to be good, but fashion over function and planned obsolesence made them shit aside from 'looking good', which i both don't really care about AND usually consider ugly or gaudy and cringe.
Airwalks were the worst, i used to wear OG Airwalks and Vision Street Wear back in the day and both were solid and would last. It took skating big roof gaps to collapse the soles. Now Airwalks won't last a single park session, i blew through two pairs of Airwalks in a day and was skating barefoot by sunset.
I wear pretty much only modded DC Courts these days, only shoe with a decent shape and big toebox i can find, even other DC models don't fit right. To keep them from collapsing i strip the guts out and bed the midsole airgaps with shoe goo, about 1.5 tubes per shoe and make the entire midsole solid. I also reinforced the inside seams with a layer and so far it's lasted about two months with no signs of collapsing. I just don't understand why they can't make a shoe like that from the factory, even as a paid upgrade. It costs me like an extra $30 of shoe goo and a few days to cure, i'd gladly pay an extra $40 or so for a legit solid shoe i don't have to disassemble and rebuild.
But like FFS if you're selling a size 18 shoe you'd think they'd make it with a midsole that can bear the weight and forces of someone with size 18 feet. I'm not a 90lb wealking on waterskis, if i'm fasting and down to skin and bones i'm still around 220lb naked and more with all my gear and backpack and whanot.
I heard Supras have a solid urethane midsole, i've always wanted some so bad but they don't make anything bigger than 14 IIRC.
I originally got into 3d printing with the intention to make my own shoes back in around 2012-2013, i wanted to make molds so i can pour my own urethane midsole parts from quality materials instead of crap like EVA and mushy weak rubber and roll my own uppers, but i got distracted by all the other cool things it can do. Lately though i've been heavily into 3d printed moldmaking and have a lot of knowledge and experience that will help me out, so they might just be coming soon.
But as for the directly 3d printed shoes, they all look like disposable gimmick fake swap meet louie yeezies, and yeezies are just glorified atrocious looking crocs in the first place. But then again that's pretty much all modern shoes. They just don't make 'em like they used to and nobody seems to remember back when they weren't all single use disposable fast fashion trash.
Shoes should last much longer than a year. That's so much waste.
I think we are barely grazing the surface for sure. Hiking boots with spiky bottoms and stretchy latches that fix them firmly to your calf? 3D printed material interwoven into a traditional manufacturing fabric or tread to give it the ultimate bond? So many avenues.
What I am curious to see is a hybrid boot. I am into traditionally made leather boots, and have been learning construction methods, and I am interested in these. I wonder if a boot that utilizes a hybrid of something like a leather body with tpu at the flex points, (decreasing crease lines in certain areas) along with a tpu outsole and something like ABS or another stiff material for a shank and maybe parts of the lugs, among other things, could be viable.
Would be interesting if one of these lasts longer than a regular foam shoe with the different material. My shoes right now have a super big hole after a year. The foam shoes use just isn't very strong
…it’d be great to add 3d scanning to the mix so that the result was a shoe printed to order that was an exact fit, even for feet that were a bit wider, narrower higher etc
Zellerfeld does that with their shoes. These were just samples to play with
Never judge a man until you have walked a mile in his 3D printed shoes.
High-5!
then you say humongous feet I have to ask what size you are? I am apparently a size 16 if I convert to us sizes.
It just dawned on me that at some point 3D-printed shoes might be a thing for orthopaedics to help flat feet like myself
question is how long did the addidas last before they started breaking?
Around 3 months
11:35 big toe box for the squatch toes. 😜
The part at the end got me thinking. Someone should 3D print a steel toe shoe 🤔
I have the catch 22 that "walking around a city at a quick pace" combined with "sitting still at a desk" is apparently how to utterly destroy shoes. The sole rips off, it gets punctured, the fabric rips, it gets bad and this tends to happen in 3-6 months... the catch 22 is that I've had this happen with budget shoes that cost $20 and more expensive shoes (the highest I went was $70...). I walk rain, shine, and snow, and remember asking Pooch about the Adidas and he said "it's fair weather footwear" and if I'm gonna spent 3 figures on shoes, I'm doing it once, not for fair weather + bad weather. I just can't bring myself to spend $100-$300 on shoes that could get destroyed in 3-6 months. I have a bunch of friends who tell me "it's higher quality, it will last longer" but after poking them they eventually get to "well, you'd probably destroy them in the same time but for a high quality shoe, you can get it repaired" and I had to bring in consumerism: $100 for 1 shoe every 3-6 months vs. $100 for 2-5 shoes that each can last 3-6 months... I'm gonna go with the cheaper shoe.
All that is to get to the point: I'd love to 3D print my own shoes or the parts of the shoe that break... and right now, cost vs length of time it lasts is not there, and then seeing the quality issues with the Adidas just makes it harder still. One day.
I would love to 3D print my own shoes and be somewhat comfortable. It would be a game changer for making it your own design!
Vivo is also starting with 3d printed shoes with the scan of the foot
Zellerfeld did it first !
@@JSZ69420 Your not wrong but competition is always good.
As you have an XL as well as other big printers (like the Orange Storm Giga), I was expecting at least one or two pairs of self-printed shoes... even I have done it on my P1S. Which was, to be honest, not working really well as my feet are to big. The shoes finished, they fit - but they are not really nice.
怪獣(kaiju) means monster btw.
I think we're overlooking a MASSIVE market edge here ... custom orthotics printed into the shoe. pair that with some more traditional shoe styling and you'd probably devastate the shoe industry. just about everyone has a CVS or similar somewhat near them with one of those dr scholl's foot scanners near the pharmacy. just send in a pic of the graph and here's your shoes.
Those first shoes look like they would really hurt if they accidentally hit your calves...anyone know what printer that is with the glowing red acrylic in the background??
That's an interesting dynamic: resolution from 1975 printed in 2024. 😁
As someone who is a Pedorthist by trade, some of the complaints about the Adidas you made are also on you as the user, specifically the upper ripping. Sizing is never accurate and consistent, that's why it's broken into a 'measure and fit' process. You should have a clearance from the longest foot from the longest toe to the end of the shoes but 15-20mm, more towards 20mm if you're a runner, this is due to flexion like when you flex a deck of cards, the direction you flex the cards, the inside cards will extend further than the outside cards, this is referred to as differential elongation, with shoes this is the foot and shoe, causing your toe to creep close to the end of the shoe. The shoes are also doffed and laced up, which suggests you're donning and doffing these without undoing the laces, which will create shear as your foot slides back an forth adding to the trauma to the upper.
All this ability to fix the issues with current footwear and none have addressed the heel height and shoe box width. Barefoot shoes are the way, and 3D printer creators can make a zero lift heel without issue yet still make these sweat inducing foot deformers.
Working on it!
3d printed work shoes would be awesome in work environments with non slip shoes with company logos.
I still think they should implement this with 3D scanners to get the perfect size for everyone's feet, it's the best process for it (and also not make narrow shoes with it which causes everyone's feet all kinds of problems..)
I have honestly zero interest in a fully 3d printed shoe. Go for it with the sole but give me a textile or leather upper.
Zellerfeld is awesome !
Anybody know what material would be best to 3d print sockets for driving bolts/nuts?
You’d want something a bit reinforced. Hand turning could easily be a PETG or ASA / ABS. However for driving it with a tool, you’d probably need CF Nylon.
@@3DPrintingNerd thank you, I have tried 100% infill PETG-CF and it mushroomed around the driving tool. Would you think something like ABS or ASA better? Or just go straight to CF Nylon?
I wanted to know how long they lasted and what you could print them on. If they only last a few days or you can't print them at home, they are not yet worth it.
All the shoes he's shown are daily wearable in my experience and opinion. And of course Joel has a pretty excellent track record oh honest and realistic reviews
As a runner, what I really want is a shoe where I can 3D print a replacement outsole!
I see you have all the filaments back there, exposed, you dont have problems with humidity?
No I don’t.
How to find good shoes that I can print?
Now you wear those Zellerfeld shoes regularly for half a year and tell us how they hold up. Thanks in advance. :)
There's a guy who's done well over a million steps in them already, works as a warehouse picker I think
There is a “left and a right”, maybe I can finally get unlimited left shoes 🤔
I love the idea of 3d printing some parts of a shoe, but I would absolutely not wear one that was 100% printed, they all look clownish. Adidas are on the right track, it's too bad they cheaped out on the materials for the top, but that's a great concept.
I'm still not clear on the advantages of the 3d printed parts.
@@harmless6813 You're on to something. In the case of Adidas the 3d printing was to create a complex pattern of gaps in the sole that made it springy. Looks like they printed that with rubber resin, which is likely way out of reach of most of us.
If I were making my own shoe, I wouldn't take that route at all. I'd design a sole for my foot, add the traction pattern I want, then FDM print a sacrificial negative of it, and use it to cast a rubber positive. Voila - now I have a _real_ sole, one that is durable and flexible. Then I'd 3d print a jig to help me assemble an upper around, also shaped for my foot, and around that jig sew an actual upper out of nylon fabric, once again, like a _real_ shoe. Then glue the upper to the sole using whatever black magic glue sneaker makers use.
This sounds like way more work than just sending a shoe STL to a printer, but I get a _real_ shoe out of it, and my 3d printer would help a huge part of the way. Shoe's are not made from a single thing, they're complex devices that have to be comfortable, durable and breathable.
FWIW I use 3d printing to make design concepts for clients - clients want concepts in epoxy, silicon, cement, plaster etc, but 3d printing makes it so much easier to shape those media, and all my clients love how the 3d printing is helping them zero in on manufacturing questions from the very start of the process.
I’d just like for them to make a custom insole file that I can print to put in any shoe (even my 👠 ) that works for my high arches.
BLESSED
I'll say the shoes in the video need pull tabs at the back of the shoes since often times the shoes are just big enough to fit your foot and ankle and doesn't always have space for a finger to get in the shoe to get it on the foot right.
Adidas needed to make some hook and press fit points on to their carbon fiber mid sole allowing the bottom sole and the traditional top part of the shoe,
to better adhere to the carbon fiber mid sole since the different materials mean all pieces of the shoe aren't able to stick to each other for long time; were if the carbon fiber mid sole had hooks and pressure points for other parts of the shoe then the other parts of the shoe will stick to the carbon fiber mid sole over and over again throughout the daily use of the shoe since other parts of the shoe will keep on sticking to the carbon fiber mid sole better through the every day use of the shoe as they break in and set/stick to one other the person wearing the shoe moves around in them.
Yes, I made it to the end and I'm still waiting for the test to begin...
Would love to 3D print myself some shoes as I really struggle getting shoes in my size! (Size 16 UK, 17 US)
Looks like one of those feetz shoes took up smoking lol.
I'm happy you refer to the Adias shoes, not as 3d printed, but note they use a 3d printed component. The idea that if something has some percentage of 3d printed components, that people call them 3d printed is like nails on a chalkboard.
e.g. - a computer case which is composed of about 75% 3d printed components, is not a 3d printed case.
Every industry does this. In the beef industry it’s “angus”. The definitions get skewed to mean something very different than the consumer is lead to believe. And most of the time, we consumers just go along with it because we don’t know any better.
3D printed shoes should have built-in ductwork to provide ventilation.
"How you gonna take them off, nerd!?"
5:07 I think they 3d modeled and printed the originals the injection molds were made from.
it would be nice if you got to adidas shop and they make your foot mold or scan and make 3d printed shoes just for you. that would be future thinking
8:10 they need cow hide uppers with carbon lowers rather than synthetic crap with carbon.
Yeah - I know the carbon is synthetic too…buts it’s durable.
Wait till they get plant based 3d printed material.
Plant based 3D printed material like PLA?
finally we need to go on thats soo cool
I'd rather print my own shoes -- looking for good files. 😁
those Kaiju's are awesome
someone had to test them all 👍
Came here looking for a test of the 3d printed Crocs and was wildly disappointed. ALL of the 3D Printed Shoes? Testing? U WOT M8?
These are shoes available to purchase from companies - not stuff I 3d printed myself. SHOULD I PRINT CROCS?
Vivo Biome, might be an intresting search for shoes.
😂Those are some cyber truck shoes..
I feel like you should have addressed the price of the zellerfelds. They're almost $300. Way too expensive, especially since the filament cost is probably very low, and they aren't customized for the customer
There was a lot of r&d that went into the custom design and custom material. The product is still in a novelty stage and not willing to be widely adopted because it stands out too much, and a simple design change cannot fix that, the goofy design is fashion hiding a larger issue with 3D printed shoes preventing them from being more traditional, weather that is durability, comfort, breathability, or all of it. For these reasons the cost can be justified.
Source: from personal experience try making some that fits all the requirements for regular mass adoption, the final 10% is very hard to solve.
After watching this, I'm of the opinion that someone needs to go back to the beginning of footwear and make a parametric sandle with a conpliant mechanism to strap them on. You know just enough shoe to provide a sole and maybe a bit of a toebox. But... least possible. This is just because, the less shoe there is, the fewer fail points it has.
Zellerfeld's are like 300, just FYI.
the blue shoes were probably "designed" on 3D software. the most it would be close to 3D.
So, like any other (modern) shoe?
You're not meant to wear the same pair everyday... You'll make 2 with 2 pairs. You need to let the shoe fibers de compress before wearing them again. 1 day will do.
I would have bought the zellerfeld shoes but they’re very expensive
I allllmost printed a pair of crocs - but thankfully that was only a three second thought…
you should 3d print a sweater !
Rubber clothes exist. It's called a hazmat suit.
