  • Great for long walk 👍
Size: 8.5 Color: Black/Carbon/Active Teal
These are super comfortable and perfect for long walk. On weekends, I walk to & from work for 13 miles total 🤯 wearing these pairs and never has blisters or joint pain. They are comfortable and have enough cushion for your ankles. I also run on them on trademill and they seem to handle the impact when your foot landed on the running deck. The upper part of the shoe is made of elastic fabric which allows easy stretching and tight fit. Great shoes and would recommend it. ... show more

  • They're real and they're spectacular
I just got these shoes so I haven't had a chance to wear them for a long time. I am replacing a pair of Ultraboost19 (which seemed pretty much the same as the Ultraboost20). These are definitely different. More boost (performance and looks), stretchier upper (more like spandex rather than the old pair that seemed more knitted), and more ridgid sole. Here are just a couple quick things to draw attention to that I wouldn't have minded seeing. - Fit: I think they fit the same as my UB19. For me, that puts me in between sizes. My foot is on the wider side (not multiple E, but D can be snug). The 10.5 fit, but my toe was pressed almost to the end. For the UB19 I went with that 10.5 and sometimes regretted not sizing up. This time I ordered both a 10.5 and 11. The fit seems the same as the prior pair. This time I'm going with the 11. - Color: I got the gray, with gray boost. It's a relatively light gray. I'm hoping the gray boost keeps cleaner for a bit longer than more standard white. The real test is that my sneakerhead 15 year old thinks they look great. - Real/fake: There seemed to be some comments asking about whether these are real or fake, and some of the comments said they're fake. I can't speak for all of the options, but mine are from amazon.com as seller. They are definitely real. - Price: The price has been odd. I got them for $126. There were only a couple pairs at that low price and I actually liked the gray as much as any other color. It seems to fluctuate between the $126 and $175 on Amazon though. - Performance: As I mentioned, I just got these. I bought them as an every day sneaker and for running when I'm traveling (rather than brining another sneaker). I run in a Brooks, but primarily because I already have them and they are a bit lighter. The Ultraboost certainly feel comfortable and I'm curious to run in them in them sometime soon. ... show more

  • Should you buy these?
I skeptically bought these shoes thinking they might be potential fakes, to my surprise they are either 100 percent authentic or amazingly recreated pairs . I checked for any glue marks, the knitting, and branding on my all white pairs and everything is in line with Authentic ultraboost21’s. My experience with these so far (about 1-2 weeks in): The first wear they might feel a little tight around the toes compared to older models, but it quickly goes away by the second wear. Quality and comfort is what to be expected for any ultraboost, amazing. I use these shoes for workouts, everyday wear around campus, and running and they always meet expectations. Aside from that the styling is amazing and very versatile with what ever you wear. Over all I am an ultraboost lover, and being able to get them at this price is amazing. Hopefully this was able to help anyone make a decision on purchasing. 100 percent recommend buying these shoes, if you’re thinking about it just pull the trigger you won’t be disappointed! ... show more

  • Great Pair Of Shoes
Size: 11.5 Color: Sonic Ink/Black/Screaming Green
Not exactly sure who sold this, I suppose I assumed it was from Amazon, but it came in a sealed bag and no box, and that's a first for me from Amazon. It is pretty standard from ebay however...but again, I didn't order them thru anywhere else. Maybe it was in the description and I missed it? I am not particularly upset about it because the price was definitely less than I saw the same pair for (brand new) anywhere else online...so don't let that color your opinion here. They arrived timely, which is always nice. They are comfortable, which I expect from Adidas. In all the years I've purchased shoes from them, only once have I been disappointed in the fit. But that does not count here. I wasn't uber keen on the color, but again, the price made me willing to deal with it because that isn't ultimately the main reason you should buy a pair of shoes. The Ultraboost shoes have an abundance of the foam that Adidas uses to cushion your heels in particular while walking/running and it does a pretty good job. If I had to point to the pair of shoes I own that has the most cushioned experience, I'd say it was the recent pair of OneMix running shoes I got shortly before Christmas. I would've guessed these were just as cushiony, but they aren't. That doesn't mean they aren't good though. They envelop your feet and fit well - although I should point out if you have wide feet, you're going to want to hold off until you can get a pair that isn't as narrow as these. I have fairly narrow feet and they are a very close fit for me. I am really warming up to shoes that do not come with a traditional tongue. It took me a bit to get used to the design but honestly, they don't feel any different in my opinion. They are comfortable (at least the ones are that I own) and I will definitely be buying more in the future. In short, great shoes and great fit, but keep in mind if you have a wide foot before buying and good luck! ... show more

  • Quality Shoes for fitness
Size: 9 Color: Grey/Grey/Grey
I purchased a black pair of ultra boost for my partner two years ago and he absolutely fell in love with them that he wears them everyday and they're still in good shape today. I decided to purchase the grey pair for him as well. These shoes are very comfortable for walking or running or at they gym. They provide comfort and stability for the ankels. The soles are really thick which is great the shoes can last longer. ... show more

  • Comodidad
Size: 8 Color: Black/Black/Grey
Los tengo hace mas de un año y creo que han recorrido mas de 1000 kms y siguen con la misma comodidad y calidad. El boost blanco se pone amarillo con el tiempo y es lo unico que me molesto.
