First off love the channel.. anyway you could do a Carolina foundry boot with metatarsal guard review. I own a pair and love em. Also own a pair of doc marten works with metatarsal guard. And those not so much. Thanks in advance. Keep the video's coming
Boost actually has changed throughout the years, early boost was softer than the UB2022 which is more firm because the new shoes are more focused towards performance.
Yh but it’s not only the ultra boost that has boost like the UB has always been firm compared to like pure boost and others even in different ub from the same year there’s differences in firmness
they're "dead" as in the hype for them is dead, which is an AWESOME thing, I grab myself a pair of OGs almost every year when they get to be 40% off, they look good and feel good!
@@Kashsneakers Apparently the comment right under the thread said that it is a known thing that they do bottom out, so which one is it people X( Personally, I have a pair of 380s I wear daily and they did start to feel like they were getting smashed in on the inside even while I loose a few pounds
Only trends die, I merely take from them what is timeless to me. I do really like the ideas trends can provide, though there's also just certain color/texture palettes etc. I like in all sorts of design, I'll take queue's from interior design trends etc. too, but with clothing trends you can capitalize on just how much of it is being produced and get full longevity out of it.
ZoomX is much less durable than boost. I’ve had boost shoes for 3 years now and the midsole is still in amazing shape. ZoomX usually last 200-300 miles
AGREE! It seems like the Nike foam, being solid, would eventually compress and lose the bounce-back that it has new. Whereas, the Adidas Boost foam may stay more responsive over time, given the honeycomb structure he pointed out.
it would be no compairison at all. Boost lasts YEARS!!! My ultrboost 19 still fee new and have molded to my foot. I cant belive how durable they continue to be. Even the outsole looks brand new after MCUH use.
I'm a long distance runner and I LOVE boosts, they're my go to running shoes. I find them very comfortable and extremely versatile in every run I have thrown at them in various temperatures, seasons and weather and my Adidas Boost 20's have not let me down yet. I did a half marathon with a personal best time of 1:26:38 earlier this year in them, I highly recommend these shoes!
I ran about 3000kms in a pair back in 2017 and i still use the shoes for some walking and everyday light movement. Sure the outsole is destroyed but no tears,rips and still comfortable.
Since you're now delving into the world of cushion heavy running shoes, one interesting material from a well known running brand would be Asic's Flytefoam and Flytefoam blast and its plus version. I would suggest cutting in half Asics Novablast which is similarly constructed as the Nike Zoom Invinicible.
The good thing with boost is it doesn't get flat through time. It holds its structure much better than other foams. I had the Nike react Flyknit 2 and they died down really fast. Boost doesn't bottom out that fast or maybe at all.
the oldest boost shoes i got is an OG ultraboost 1.0 from 2015, and a pureboost DPR as my go-to, beaten up running shoe since 2018. both of them still feels basically unchanged since new… so i’d agree, i have yet to see boost bottom out! the same cannot be said with my other sneakers, e.g. my 2018 nike air presto. it’s still bouncy where the air unit is, but now it is in a pretty awkward form where since the foam has flatten out, the side cage protrudes too much into my foot arch
Okay, that heel counter area for bigger people like myself is the best thing in the world because it feels like your foot is molded into the shoe. Almost, it really locks in your foot if you get the right size. And with other shoes like Converse, sometimes I legitimately feel my foot moving around on the inside of the shoe and I don't really care for that too much. I have never felt that with my pair of ultra boost 22s
Great video. I work for adidas and there is a nuance here. For the top of the line performance running we have different kinds of BOOST. What you reviewed here is the older baseline tech which is also used for casual wear. I wonder how the top of the line running BOOST would add up. Or some of the adizero line which uses a new foam all together. Anyway super interesting videos as always
i love the older boost sneakers not a fan of the recent ultraboost line i think they need more boost under the toes and a wider toebox option, hence why the saucony triumphs are my favs
Since the shoes are being worn more for casual wear than athletic, should long term durability be considered and taken into account when comparing foam?
I'd love to see a cross section of the new Adidas 4D FWD! They recently replaced my ultra boost as my #1 daily sneaker, and would be cool to see how it compares!
on older models of the ultraboost it was a continental rubber sole that lasts seemingly forever. plus since its a piece of rubber it wouldnt be impossible to replace it with a vibram pad when they eventually wear down. the boost itself also holds up really well to wear because mine are literally just kinda dirty but otherwise fine
Talking about Zoom X foam and Zoom Air units, the Nike Tempo Next% trainers is astonishingly comfortable albeit expensive and not durable. The thing is perfect for anyone that’s overweight, flat-footed, or with a bit of arthralgia. The con is that the bottom sole at the back is incredibly thin so eventually the Zoom X will wear out. Pros is that this shoe makes running feel fun and easy which is what people need when they’re looking to exercise more.
So my first ever experience with Boost foam was the lightboost shoes. They were marketed as running shoes and I used them as such. They’re not great. My saucony trainers and Nike race shoes both perform better (triumph 20 and Vaporfly 3) at their intended function. The foam started to compress really quickly and it just doesn’t feel great underfoot. I now use them exclusively as a lifestyle shoe, which they are pretty good for; stable but squishy and light, pretty breathable, very wearable. In short, great as a more comfy higher-end lifestyle sneaker, but as far as their marketed use, not great.
The only problem with boost is, the sneakers they chose to put it on. I just can't do sneakers with a booty fit, which is the way the Ultraboost has been made from day one. And mostly the model that features the technology that releases constantly. Just a few months ago I scooped some Parley Ultraboost 21's and, they hurt to wear for me right at the instep. If they did them with a traditional tongue, I wouldn't have problem wearing them. And speaking of Nike, before I got my 1st pair of Adidas with boost, I got the Prestos with React. Which I dare to say, they give Adidas Ultraboosts a run for their money. And for even cheaper retail. And even though those have a booty construction as well, I can wear them just fine. It can be done, Adidas. A booty sneaker that everyone can wear. Just do it!
The first boost shoe doesn't actually feature anything near the BASF foam version. The first cushion is more akin to "Bounce" technology that is comprised of plastic spring like frame enclosing a foam compound. Something that looks like the springblade or microbounce technology (which was the bounce technology before it became another foam compound).
You mean the pureboost? They were actually incredibly comfortable, they weren't tailored for any purpose, so they just went wild and made the best boost shoe possible. The earlier boost shoes were actually better and more comfortable than the modern ultraboost, because the new ones are geared towards better perfomance runners, so they were made more stable and less soft.
Boost will always be awesome. Its still very comfortable and the prime knit is better. Comfort is evwrything. The feel of putting on a pair back in 2016, I never put on a pair of kicks where I just got a big grin nothing was as comfortable as those. Then the whole yeezy line with boost and then a cage around it has made them even more comfortable. In my opinion, only other shoe to ever achieve this level of comfort but ALSO last for atleast half a decade of everyday wear is the new balance 992s or 993s. I still have a pair of beaters from 2006 that still fit excellent.
Having had a couple of ultra boots over the years and both still going strong I love them I have had 3 back surgeries so soft is my best friend for walking These are the most comfortable shoe I have ever had And yes I own all birds and that’s just marketing hype
Two thoughts regarding testing material responsiveness. 1) What if the materials have different, nonlinear responses? E.g. material A responds very well to a small weight but heavy compression causes energy loss to heating and lateral expansion, whereas material B performs worse for a smaller weight but by virtue of structural resiliency returns more energy as the load is increased? 2) Kind of related, but how about a compression test, perhaps using a pneumatic press, where you observe how much weight it takes to compress the heel stack or midsole slab to 50%, 75%, or some % of its original height? I am not a materials engineer, just spitballing as someone with experience in testing. Ps, if you do continue the bar drop test, consider anchoring the shoes to the stand to more accurately reflect them being snuggly attached to a relatively massive human and also eliminate any error produced from the shoes freely bouncing during impact. Thanks for all the great videos!
Mainly comfortable shoes is to absorb impact and bounce some of the energy, its a balance I think that really makes it comfortable. Its not abount being bouncy
I have had dozens of ultraboosts and 2 pairs of ZoomX. Both ZoomX were returned under defects because the soul splits and delams. I never had a durability issue with my ultraboosts.
Boost is a great technology, I think it is the best combination between comfortable and responsive for just wearing it as a sneaker. When it comes to sport however, i dont really like to wear it just because i want a shoe that is responsive and gives u some bounceback.
It would be great to see a collaboration with Chris from Wear testers ... would be great to see the sneaker culture input before cutting them in half :D
The LEP replaced and improved on the previous Torsion system; the boost foam maybe dated but adidas reinvented their shoe rigidity tech. I still believe in the boost, I tried it; walked with it for a day on cobble stone streets and hard asphalt and my foot wasn't tired.
I'll take a pair of Ultraboost 20's in any color way. Most comfortable shoe ever. Currently I have 5 pairs, only 1 I would ever wear because I like the way they look. All are in rotation because my feet need them.
I'm so happy to see a video about one of my favorite product/shoes on your channel (That I discovered/loved mid 2020, 'thanks' Covid! 🙈🙈) that is so well done and accurate. And cool; too. Hope the cat is still messing around you haha 😜
I came from ZoomX Invincible Run 1 (since after about 1200km ZoomX just started ripping apart, way before at about 600km shoes lost about 50% of the energy return - checked with new pair). Now I have 3 pairs of UB22 - each bought about 4 months after each other (last pair yesterday) and there's absolutely no difference between energy return - and it's worth to mention that my first UB22 has about 1800km stand (I know quite precisely since I use GPS tracker in my watch). Never ever ever am I going back to ZoomX. ZoomX is softer and generally better at first, but shoes are highly unstable (like jelly), ZoomX rips like crazy, it looses it's energy return very quickly. Plus upper was kinda too hot for me.
I own a pair of Adidas with boost foam. They are really comfortable, but my complaint is not with the performance it's with the look. After some time, the white foam starts turning yellow. It happened with my daughter's as well. Work great, but not loving the look after a few months.
Havent worn too many boost but i wear my shoes at all times and i heard the reason i had sore feet with them once.. the second pair was because i heard you need to let them rest to get the boost back into optimal cushioning.. my theory is when boost is caged i think maybe it has better duration properties.. i havent tested that out but a theory.. the pair i got sore with was open boost and the first pair i had was more minimal with boost with other materials supporting the underfoot.
Great video. Love all the stuff you do. I would like to see the new Brooks running shoes with the nitrogen infused foam. I like the Brooks shoes and just like to see how they would respond to the tests and see them cut in half
the issue with Nike foam is that it does not last long. it difroms, colapses and develop missalignment issues with time. i rock my adidas ultra boost for over 5 years and the foam is in the same shape as it was when i purchased them. (just a little dirty) i had to throw all my nike shoes because the foam on the heal lost it's shape and made me walk strange. also all my back pain and legs went away when i stopped using them. i was a huge nike shoes fan until i found that you need to change nike shoes in about a year or two so you won't get health related issues.
Shoe technology hasn't changed for two decades now, it's just the same process with little changes here and there, like material, compound or different gas
I dont see no spring when I wear my 22s lol I just see it as a normal running shoe I see nothing different except its more head support and comfy to wear
ball drop test is hard to analyse. Try a piece of a solid hard rubber - according to the ball test drop it will be probably the best efficient sole :) Remember what is inside of golf balls?! :)
My casual shoes, full of nike, vans, converse, NBalance or whatever, but my workout shoes always Adidas, especially the boost one, i dunno , those gave me great feeling
BOOST its life!! And "still" is😜 Give me Ultraboost every time and every day! I'm Big, heavy, and have problems in my knee and Boost change my day to day beacause of this shoes...and they begun the fight gor every one else yo match this level of confort and response. Now all brands are into thanks to Adidas and boost
could you record cutting some vagabonds? they are little cheaper than dr.martens but I see them everywhere and I think they are not a great quality. thanks
thanks for another great video . Can you please please do a review on Allbirds Merino Shoes . Made from NZ Merino fine wool , weaved in Italy and finally sewn together in Soth Korea - No China or Vietnam for once . It will be a challenge for you as shoes using a fine Merino Wool is unique - so please do a video on these totally Unique shoes . Only the Wool Allbirds are made in South Korea - which has a great history in shoe / boot making long before China / Vietnam came on the scene .I have yet to hear any anti Allbird reactions / comments so Please do it and funk up your channel a little with a unique shoe / boot .Be nice to learn of other shoe / boot makers that are not Nike or Adidas. Many thanks .
Great job! I know this was a very hard full time research, I appreciate this awesome video. Added to this the nike Zoom X is the best foam, very responsive, react and soft, therefore adidas need to found a new technology, lightstrike pro isn't the way.
I wonder if the solid Nike foam will compress more and or more quickly over time. I’m a heavy person and tend to break down regular shoes pretty quickly.
There is a big diference whit boost and zoom x boost is more durable i have shoes with 1000/1500 kms in use with boost and zoom x last no more than 300/500 kms! Other diference is the temperature boost works fine in cold but zoom x got stifer!
I think one thing to consider is that BOOST lasts SOOOOO much longer than standard EVA foams, so even though Zoom X and even adidas LightStrike foam is bouncier, they don't stay that bouncy for nearly as long as Boost does
Was about to ask about this. Most people (non-runners non-hypebeasts) expect their shoes to last up to 5 years. Some of my boost shoes are 5 yrs old and still feel great. Not as bouncy as new ones but the "bottom out" on them still feels soft and responsive after many years.
Simple answer is : no. It's one of the best cushioning there is. I'd buy a lifetime supplies of ultraboosts 19. Super comfortable and surprisingly durable.
Gotta try the 19s. I'm a diehard fan of the ultraboost ATR MID. Just bought another ultraboost 1.0 on sale. Most comfortable shoes I have ever worn is ultraboosts while having durability.
I'm starting to get really impressed by the iterative testing on the energy return from the foam. Cutting out little cross-sections to remove variables and standardize the process as much as possible shows you really are committed to trying to get meaningful results that can be compared and it's not just a cool-looking garage science test.
If I'm not mistaken, the boost on various version of ultraboost is different. The classic ultraboost is much softer if compared to the ub 19/20 because both of them got increased density by around 20%? and for ub 21-22, they increase the density even more than the ub 19/20. Perhaps a lightstrike shoe gonna be a fair comparison for zoom x as it is more suitable for running..
As a runner i can confirm that from ub19 the foam has been less soft. From a runner perspective Is not a "bad" thing, but for the people who use them as sneaker the earlier version were comfier
That's true. Lightstrike pro is the Adidas' equivalent to Nike's zoom x. It is used, though, only on performance shoes, like Adios pro, or Takumi sen. Adidas doesn't have a casual - running shoe with lightstrike pro, like Nike's invincible run.
Boost and double stacked Zoom are my favorite cushioning technology of all time. The main advantage of Boost is how if performs in a wide range of temperatures and how quickly the cushion springs back; no dead spots. Great thing is seeing the evolution of all these foam tech.
I was working in running retail back in 2013. I remember when I first heard about Adidas Boost from the sales reps. It sounded absolutely incredible and I made sure to buy a pair when they first came out. Running on those shoes back in the day was nothing like I felt before. You literally felt like you could keep going forever.
I'm a heavy dude, around 105-110kg in weight, with bad joints and pain in my feet whenever I'm on my feet for over an hour. My first contact with Boost foam was via a pair of light Puma sneakers with their version of Boost foam and knit upper. I loved them because they were light and breathatble but most importantly the comfiest shoes I ever had. That Boost foam was soft and bouncy really made it easier for me to stay on my feet longer. Also, those Puma sneakers were really cheap, like 2-3 times cheaper than any Adidas sneakers with Boost foam, let alone the Ultraboost model. Which kinda tells you that Adidas is ripping people off on it, probably based on the hype and marketing that Boost got. From then on, I didn't want to wear any sneakers that didn't have Boost in them. My current ones are Adidas ZX 2K Boost and they're damn comfortable. Boost really makes walking easier for my fat ass... On the topic of those soft foams, Boost is considered a "boomer" one. There's a bunch of more recent and modern soft, responsive foams from multiple brands. Nike's ZoomX is one of them, New Balance has Fresh Foam X in their 1080 V12 model, Puma has their Nitro foam, I believe Asics, Mizuno and some others also have their versions of an ultrasoft and bouncy foams...Some general rule to them is that the softer a foam is, the lighter and less durable it is. ZoomX falls within that very soft and bouncy but less durable category and Boost is slightly less soft and bouncy but much more durable and retains its shape for longer without being squished or warped. I haven't tried those other foams for I can comfirm that the Boost is indeed durable...that knit upper on my 3 year old Pumas started to tear, the outsole is worn out but the Boost midsole is just as soft and bouncy as it was.
Might be a great investment for me. I have been having depression for over a year now, it made me physically inactive. I've been having trouble to getting used to using my feet and legs again, hell I even sprained my ankle twice back in Dec last year and this April. Idk what happened but my physical is just getting worse, my foot can't endure standing or walking intensively or my front calves would get cramped and feet starting to hurt. Saving to get any of the boost foam shoes see how like them
Puma got those so you probably got them like at Ross or something cus I remember seeing some too. Yeah 190+ is a ripoff but i also saw plenty of boosts almost since the beginning
Boost is far from perfect, but it's also one of the best midsole materials ever created. I love both ZoomX and Boost, but each fit a different category for me. ZoomX is softer, bouncier, and also far less stable than Boost. Boost is heavier, more dense, but also far more stable and will not bottom out like ZoomX will. If I needed a shoe that is good for constant motion, then I would pick a ZoomX shoe. On the other hand, if I needed a shoe that I had to wear and stand around all-day, then I wouldn't hesitate to grab an Ultraboost. The better comparison would be ZoomX and Lightstrike Pro. Both are used for high end running shoes and compete in the same space.
Boost isn't very good for standing around all day in, the boost starts to feel like puddy and make your calves and feet fatigue trying to keep you stable standing still. You need something a little bit more firm for standing around all day.
@@gilbertoflores7397 You just need a better boost model. The ultraboost is for running, but a 93/17 or something would let you stand easily. You can easily judge a shoe's purpose based on their shape.
@@Oyashio202 those are worse, do you have any of of the boost eqt? A majority of the boost isn't even felt, most of the boost protrudes past the foot and is purely for aesthetics purpose, it isn't any better than the a regular ultraboost in terms of comfort. People only hyped it up because it "looked" like it had more boost, but didn't have more underfoot where it mattered. And shape of shoe has nothing to do with purpose, most air max shoes are technically running shoes.
@@teng029 all day wear as in moving around and just being on your feet all day? Or standing in one spot doing some sort of factory/manufacturing type job? Huge difference in how you're going to feel at the end of the day.
One thing that all the newer foams can’t beat is how the boost able to maintain its form and bounce after many miles where most evas and pebas foam would shrink and lose / have reduced cushioning. I think boost is still unbeatable at least in lifestyle - comfort category and running in general due to the longevity of it.
I think another important metric might be the amount of force that is transferred to the ground right beneath where the ball hits the foam. Maybe boost doesn’t return as much energy as zoomx but maybe it distributes the force of your heel hitting the ground better. It would also be pretty cool to see how high the ball bounces by itself to see how much energy is lost/conserved by these foams. These videos are awesome though, not many people are doing these direct tests like you are.
I have triple black ultra boost 3’s that I’ve had for over five years. No running just casual and light yard work. They’ve held up surprisingly well. The boost midsole is painted black and no paint is chipping off which is pretty surprising. The knit upper is more comfortable than my ultra boost 1.0s but the midsole is about the same. Gonna give the newer models a try if i see them on sale.
There’s a new thing from Adidas called Jet Boost which is on the Pureboost 22. Maybe that’s the next thing? Looks like boost but the beads are much smaller. Edit: one thing that Zoom X is notorious for is lower durability. It doesn’t last as long as other competing foams. This was a few years ago. Not sure if they made improvements.
Having tried jetboost it's definitely more compressed and harder then the typical boost especially in the front portion. It kinda represents the lower budget boost shoes in where they tend to be more stiff, but we also need to remember there's still the regular pure boost that doesn't use jetboost which is like the ultra boost 21s more yes it's confusing the way you can tell between the two is the extra designs, they come in a black-green-white, white-grey, all black colorways, it also has a fake leather heel support.

Truth! Between the UB 20 and UB 21, there was something seriously changed with the firmness of the foam.
from 2019 onwards it became firmer.

Something that looks like the springblade or microbounce technology (which was the bounce technology before it became another foam compound).
You mean the pureboost? They were actually incredibly comfortable, they weren't tailored for any purpose, so they just went wild and made the best boost shoe possible. The earlier boost shoes were actually better and more comfortable than the modern ultraboost, because the new ones are geared towards better perfomance runners, so they were made more stable and less soft.
Boost nmd was immediately fire when it came out. Everyone wanted the first gen
Weston! Nike alphafly next% 2 is the top of the line for technology it is more than just the foam you should totally check these out!!
i love my ultraboost cold rdy 22, so freaking comfy to walk or run long distances on.
Ultra boosts are the best pair of shoes I’ve ever owned. Three years in and they are still solid .
Boost will always be awesome. Its still very comfortable and the prime knit is better. Comfort is evwrything. The feel of putting on a pair back in 2016, I never put on a pair of kicks where I just got a big grin nothing was as comfortable as those. Then the whole yeezy line with boost and then a cage around it has made them even more comfortable. In my opinion, only other shoe to ever achieve this level of comfort but ALSO last for atleast half a decade of everyday wear is the new balance 992s or 993s. I still have a pair of beaters from 2006 that still fit excellent.
Excellent analysis video!
Let's see one involving the new New Balance FuelCell SuperComp Trainer!
Thumbs up for the center cut alone. Love the vids.
Can u do a compression test on the heel’s to simulate the weight of a human heel. To measure compression. Thanks , I love your videos!
Having had a couple of ultra boots over the years and both still going strong I love them
I have had 3 back surgeries so soft is my best friend for walking
These are the most comfortable shoe I have ever had
And yes I own all birds and that’s just marketing hype
Please review adidas lightstrike pro foam!! Love the sneakers technical breakdown videos!!
Boost hasn't been adidas flagship running shoe midsole foam for like 4 years and is still hugely popular
Two thoughts regarding testing material responsiveness. 1) What if the materials have different, nonlinear responses? E.g. material A responds very well to a small weight but heavy compression causes energy loss to heating and lateral expansion, whereas material B performs worse for a smaller weight but by virtue of structural resiliency returns more energy as the load is increased? 2) Kind of related, but how about a compression test, perhaps using a pneumatic press, where you observe how much weight it takes to compress the heel stack or midsole slab to 50%, 75%, or some % of its original height? I am not a materials engineer, just spitballing as someone with experience in testing. Ps, if you do continue the bar drop test, consider anchoring the shoes to the stand to more accurately reflect them being snuggly attached to a relatively massive human and also eliminate any error produced from the shoes freely bouncing during impact. Thanks for all the great videos!
I love my UBs. I just grabbed a pair of Powerboost and a pair of Solar Glide. Love the Boost foam.
The knot on the zoom ex isn’t meant to stretch like that . One is a high high end marathon shoe. One isn’t .
Mainly comfortable shoes is to absorb impact and bounce some of the energy, its a balance I think that really makes it comfortable. Its not abount being bouncy
I have had dozens of ultraboosts and 2 pairs of ZoomX. Both ZoomX were returned under defects because the soul splits and delams. I never had a durability issue with my ultraboosts.
Zoom material is also too soft. It isn't as responsive as boost.
if im not wrong, the zoom vaporfly has a carbonfiber plate for the same reason as the LES plate
Boost is a great technology, I think it is the best combination between comfortable and responsive for just wearing it as a sneaker. When it comes to sport however, i dont really like to wear it just because i want a shoe that is responsive and gives u some bounceback.
I wanna see you cut a pair of PRAS shoes in half and compare them with Chuck Taylor's converse
It would be great to see a collaboration with Chris from Wear testers ... would be great to see the sneaker culture input before cutting them in half :D
The LEP replaced and improved on the previous Torsion system; the boost foam maybe dated but adidas reinvented their shoe rigidity tech. I still believe in the boost, I tried it; walked with it for a day on cobble stone streets and hard asphalt and my foot wasn't tired.
Time to compare Boost to Saucony's foam found in the Triumph 20 and 21.
I'll take a pair of Ultraboost 20's in any color way. Most comfortable shoe ever. Currently I have 5 pairs, only 1 I would ever wear because I like the way they look. All are in rotation because my feet need them.
I'm so happy to see a video about one of my favorite product/shoes on your channel (That I discovered/loved mid 2020, 'thanks' Covid! 🙈🙈) that is so well done and accurate. And cool; too. Hope the cat is still messing around you haha 😜
I came from ZoomX Invincible Run 1 (since after about 1200km ZoomX just started ripping apart, way before at about 600km shoes lost about 50% of the energy return - checked with new pair). Now I have 3 pairs of UB22 - each bought about 4 months after each other (last pair yesterday) and there's absolutely no difference between energy return - and it's worth to mention that my first UB22 has about 1800km stand (I know quite precisely since I use GPS tracker in my watch). Never ever ever am I going back to ZoomX. ZoomX is softer and generally better at first, but shoes are highly unstable (like jelly), ZoomX rips like crazy, it looses it's energy return very quickly. Plus upper was kinda too hot for me.
I own a pair of Adidas with boost foam. They are really comfortable, but my complaint is not with the performance it's with the look. After some time, the white foam starts turning yellow. It happened with my daughter's as well. Work great, but not loving the look after a few months.
You should have a look at New Balance, they got some very interesting foams
Can't wait for the Roseanvil and Project Farm crossover.
to counter this @ 4:50 the plastic goes bad way faster especially if you like tying your shoes tight when you run
have a pair of ultraboost 4.0 DNA primeblue. used for 2 yrs straight and the only dmg it has is a few scratches on the heel.
Havent worn too many boost but i wear my shoes at all times and i heard the reason i had sore feet with them once.. the second pair was because i heard you need to let them rest to get the boost back into optimal cushioning.. my theory is when boost is caged i think maybe it has better duration properties.. i havent tested that out but a theory.. the pair i got sore with was open boost and the first pair i had was more minimal with boost with other materials supporting the underfoot.
3:20 there's a picture of yeezy 500 that doesnt have a boost foam in it, on top right corner
Great video. Love all the stuff you do. I would like to see the new Brooks running shoes with the nitrogen infused foam. I like the Brooks shoes and just like to see how they would respond to the tests and see them cut in half
the issue with Nike foam is that it does not last long. it difroms, colapses and develop missalignment issues with time.
i rock my adidas ultra boost for over 5 years and the foam is in the same shape as it was when i purchased them. (just a little dirty)
i had to throw all my nike shoes because the foam on the heal lost it's shape and made me walk strange. also all my back pain and legs went away when i stopped using them.
i was a huge nike shoes fan until i found that you need to change nike shoes in about a year or two so you won't get health related issues.
Love these videos. Always tune in!
My podiatrist recommended it so, I’m all for UB series.
Shoe technology hasn't changed for two decades now, it's just the same process with little changes here and there, like material, compound or different gas
do a review on timberland originals tbl ultra ek+. they look like absolute monsters in all domains.
I like this. Interested in seeing this compare to ASICS and Puma’s.
would love to see the new balance 1080
Gotta love how it went from Puma to Adidas, seems that sibling rivalry never ends 😂
I dont see no spring when I wear my 22s lol I just see it as a normal running shoe I see nothing different except its more head support and comfy to wear
That boost sneaker is a lifestyle based sneaker not a performance athletic.. You should try the Adios Addizero line..
ball drop test is hard to analyse.
Try a piece of a solid hard rubber - according to the ball test drop it will be probably the best efficient sole :) Remember what is inside of golf balls?! :)
I was surprised to see boost in Reebok Zig shoes.
Yeezy 500s (one of the pictures of Yeezys you showed) doesn't have boost. It has Adiprene
Boost is so much more durable that’s definitely one advantage
My casual shoes, full of nike, vans, converse, NBalance or whatever, but my workout shoes always Adidas, especially the boost one, i dunno , those gave me great feeling
Hi, you should check or analyze the Adidas Lightstrike Pro Technology...
Any thoughts on FLOAT technology by FILA?
It's an Italian brand and it's getting popular here in Brazil
BOOST its life!!
And "still" is😜
Give me Ultraboost every time and every day!
I'm Big, heavy, and have problems in my knee and Boost change my day to day beacause of this shoes...and they begun the fight gor every one else yo match this level of confort and response. Now all brands are into thanks to Adidas and boost
could you record cutting some vagabonds? they are little cheaper than dr.martens but I see them everywhere and I think they are not a great quality. thanks
You should do one of the Adidas 4D shoes!
thanks for another great video . Can you please please do a review on Allbirds Merino Shoes . Made from NZ Merino fine wool , weaved in Italy and finally sewn together in Soth Korea - No China or Vietnam for once . It will be a challenge for you as shoes using a fine Merino Wool is unique - so please do a video on these totally Unique shoes . Only the Wool Allbirds are made in South Korea - which has a great history in shoe / boot making long before China / Vietnam came on the scene .I have yet to hear any anti Allbird reactions / comments so Please do it and funk up your channel a little with a unique shoe / boot .Be nice to learn of other shoe / boot makers that are not Nike or Adidas. Many thanks .
Zoom air is still King after all these years. Damn
Most the yeezys have boost but the 450s you showed shouldve been adiprene midsole tech.
Great job! I know this was a very hard full time research, I appreciate this awesome video. Added to this the nike Zoom X is the best foam, very responsive, react and soft, therefore adidas need to found a new technology, lightstrike pro isn't the way.
I wonder if the solid Nike foam will compress more and or more quickly over time. I’m a heavy person and tend to break down regular shoes pretty quickly.
I don't think that spring is going to propel anything over the weight of a dime.
Been waiting for this vid
There is a big diference whit boost and zoom x boost is more durable i have shoes with 1000/1500 kms in use with boost and zoom x last no more than 300/500 kms! Other diference is the temperature boost works fine in cold but zoom x got stifer!
i wish you compared it to newBalance's fresh foam.
test the Brooks Ghost.. it's my go to running shoe..
I’ve been waiting for this video.
not to b annoying but the 500 uses adiprene instead of boost! its ays so on the oustole
To me boost is like having a bed that is too soft, I need more support
Do Vapormax next please!
I would like to see these kind of tests with FP footwear or their footprint aftermarket insoles that supposedly use non-newtonian material
I think one thing to consider is that BOOST lasts SOOOOO much longer than standard EVA foams, so even though Zoom X and even adidas LightStrike foam is bouncier, they don't stay that bouncy for nearly as long as Boost does
Facts. My boost shoes still feel good after heavy use.
@@francisportugal5584 my boost shoes was still bouncy after 3 years of daily and only threw them out after the tops separated from the sole
i have a pair that is 8 years old and the sole is still good. the top has a few holes from when i was drunk.
It will outlast the sole and the upper 😎
Was about to ask about this. Most people (non-runners non-hypebeasts) expect their shoes to last up to 5 years. Some of my boost shoes are 5 yrs old and still feel great. Not as bouncy as new ones but the "bottom out" on them still feels soft and responsive after many years.
Simple answer is : no. It's one of the best cushioning there is. I'd buy a lifetime supplies of ultraboosts 19. Super comfortable and surprisingly durable.
It’s a great shoe for comfort. I don’t even take them off inside
AMEN on the 19s just bought the DNA 19.5 on sale last week, i cant wait to rock these again. 19s are POGGERS.
the 19 is amazing! still rocking mine and they barely have any wear with tons of use. Not a fan of the newer versions.
I def like the 19s much More than the 21 and 22. would love to Buy a Ton of 19s
Gotta try the 19s. I'm a diehard fan of the ultraboost ATR MID. Just bought another ultraboost 1.0 on sale. Most comfortable shoes I have ever worn is ultraboosts while having durability.
I'm starting to get really impressed by the iterative testing on the energy return from the foam. Cutting out little cross-sections to remove variables and standardize the process as much as possible shows you really are committed to trying to get meaningful results that can be compared and it's not just a cool-looking garage science test.
It’s science
Well said, these sorts of things should be publicly appreciated so he's motivated to do more. I found that to be fascinating too.
If I'm not mistaken, the boost on various version of ultraboost is different. The classic ultraboost is much softer if compared to the ub 19/20 because both of them got increased density by around 20%? and for ub 21-22, they increase the density even more than the ub 19/20.
Perhaps a lightstrike shoe gonna be a fair comparison for zoom x as it is more suitable for running..
As a runner i can confirm that from ub19 the foam has been less soft. From a runner perspective Is not a "bad" thing, but for the people who use them as sneaker the earlier version were comfier
I think there's even a difference in lifestyle and running boost.
That's true. Lightstrike pro is the Adidas' equivalent to Nike's zoom x. It is used, though, only on performance shoes, like Adios pro, or Takumi sen. Adidas doesn't have a casual - running shoe with lightstrike pro, like Nike's invincible run.
Boost and double stacked Zoom are my favorite cushioning technology of all time. The main advantage of Boost is how if performs in a wide range of temperatures and how quickly the cushion springs back; no dead spots. Great thing is seeing the evolution of all these foam tech.
I was working in running retail back in 2013. I remember when I first heard about Adidas Boost from the sales reps. It sounded absolutely incredible and I made sure to buy a pair when they first came out. Running on those shoes back in the day was nothing like I felt before. You literally felt like you could keep going forever.
I'm a heavy dude, around 105-110kg in weight, with bad joints and pain in my feet whenever I'm on my feet for over an hour. My first contact with Boost foam was via a pair of light Puma sneakers with their version of Boost foam and knit upper. I loved them because they were light and breathatble but most importantly the comfiest shoes I ever had. That Boost foam was soft and bouncy really made it easier for me to stay on my feet longer. Also, those Puma sneakers were really cheap, like 2-3 times cheaper than any Adidas sneakers with Boost foam, let alone the Ultraboost model. Which kinda tells you that Adidas is ripping people off on it, probably based on the hype and marketing that Boost got.
From then on, I didn't want to wear any sneakers that didn't have Boost in them. My current ones are Adidas ZX 2K Boost and they're damn comfortable. Boost really makes walking easier for my fat ass...
On the topic of those soft foams, Boost is considered a "boomer" one. There's a bunch of more recent and modern soft, responsive foams from multiple brands. Nike's ZoomX is one of them, New Balance has Fresh Foam X in their 1080 V12 model, Puma has their Nitro foam, I believe Asics, Mizuno and some others also have their versions of an ultrasoft and bouncy foams...Some general rule to them is that the softer a foam is, the lighter and less durable it is. ZoomX falls within that very soft and bouncy but less durable category and Boost is slightly less soft and bouncy but much more durable and retains its shape for longer without being squished or warped. I haven't tried those other foams for I can comfirm that the Boost is indeed durable...that knit upper on my 3 year old Pumas started to tear, the outsole is worn out but the Boost midsole is just as soft and bouncy as it was.
Nice writeup and interesting to hear your opinion, but in the video he shows that boost foam is softer than the Nike zoom foam
@@jackster99999 you need to rewatch the video...
@@Shithappenswhenu ah shit I got it backwards didn't I, ignore me
Might be a great investment for me. I have been having depression for over a year now, it made me physically inactive. I've been having trouble to getting used to using my feet and legs again, hell I even sprained my ankle twice back in Dec last year and this April. Idk what happened but my physical is just getting worse, my foot can't endure standing or walking intensively or my front calves would get cramped and feet starting to hurt. Saving to get any of the boost foam shoes see how like them
Puma got those so you probably got them like at Ross or something cus I remember seeing some too. Yeah 190+ is a ripoff but i also saw plenty of boosts almost since the beginning
Boost is far from perfect, but it's also one of the best midsole materials ever created. I love both ZoomX and Boost, but each fit a different category for me. ZoomX is softer, bouncier, and also far less stable than Boost. Boost is heavier, more dense, but also far more stable and will not bottom out like ZoomX will. If I needed a shoe that is good for constant motion, then I would pick a ZoomX shoe. On the other hand, if I needed a shoe that I had to wear and stand around all-day, then I wouldn't hesitate to grab an Ultraboost. The better comparison would be ZoomX and Lightstrike Pro. Both are used for high end running shoes and compete in the same space.
Boost isn't very good for standing around all day in, the boost starts to feel like puddy and make your calves and feet fatigue trying to keep you stable standing still. You need something a little bit more firm for standing around all day.
@@gilbertoflores7397 You just need a better boost model. The ultraboost is for running, but a 93/17 or something would let you stand easily. You can easily judge a shoe's purpose based on their shape.
@@gilbertoflores7397 The Ultraboost 21 and 22 are outstanding for all-day wear, as are the Solar Glide 5s.
@@Oyashio202 those are worse, do you have any of of the boost eqt? A majority of the boost isn't even felt, most of the boost protrudes past the foot and is purely for aesthetics purpose, it isn't any better than the a regular ultraboost in terms of comfort. People only hyped it up because it "looked" like it had more boost, but didn't have more underfoot where it mattered. And shape of shoe has nothing to do with purpose, most air max shoes are technically running shoes.
@@teng029 all day wear as in moving around and just being on your feet all day? Or standing in one spot doing some sort of factory/manufacturing type job? Huge difference in how you're going to feel at the end of the day.
One thing that all the newer foams can’t beat is how the boost able to maintain its form and bounce after many miles where most evas and pebas foam would shrink and lose / have reduced cushioning. I think boost is still unbeatable at least in lifestyle - comfort category and running in general due to the longevity of it.
Some say 1 year and they flat out
I think another important metric might be the amount of force that is transferred to the ground right beneath where the ball hits the foam. Maybe boost doesn’t return as much energy as zoomx but maybe it distributes the force of your heel hitting the ground better. It would also be pretty cool to see how high the ball bounces by itself to see how much energy is lost/conserved by these foams. These videos are awesome though, not many people are doing these direct tests like you are.
I have triple black ultra boost 3’s that I’ve had for over five years. No running just casual and light yard work. They’ve held up surprisingly well. The boost midsole is painted black and no paint is chipping off which is pretty surprising. The knit upper is more comfortable than my ultra boost 1.0s but the midsole is about the same. Gonna give the newer models a try if i see them on sale.
There’s a new thing from Adidas called Jet Boost which is on the Pureboost 22. Maybe that’s the next thing? Looks like boost but the beads are much smaller.
Edit: one thing that Zoom X is notorious for is lower durability. It doesn’t last as long as other competing foams. This was a few years ago. Not sure if they made improvements.
Having tried jetboost it's definitely more compressed and harder then the typical boost especially in the front portion. It kinda represents the lower budget boost shoes in where they tend to be more stiff, but we also need to remember there's still the regular pure boost that doesn't use jetboost which is like the ultra boost 21s more
yes it's confusing the way you can tell between the two is the extra designs, they come in a black-green-white, white-grey, all black colorways, it also has a fake leather heel support.
