A great update to the ultraboost line!

This shoe is very comfortable! I wear a size 13 and it fits true-to-size. I have at least 2 pairs from each yearly iteration of the Ultraboost and I think this is the best so far. Despite it feeling a bit heavier than the '19s, the wider knitting of the Primeknit material makes it feel more relaxed, aesthetically pleasing, and less tight on the foot. All in all, I would greatly recommend it for running, gym workout, or ordinary walking. Another great one from Adidas!

Ultra Boosts are 1000000% the best and most comfortable shoes ever created without a doubt. Tried these on for a casual day and I felt no fatigue or discomfort for my feet. I also went on a 5 mile run with them the following day and experienced no fatigue or discomfort. What a dub from Adidas. Miles better than anything any other company could offer comfort and style wise.

Comfortable Shoes that Make You Stand Out

I have always been a fan of the UltraBoost series. I think everyone should have a pair of nice ultraboosts for a casual night out with friends. These are the coolest looking ones that I have seen, every time I wear them I get compliments about them! It has gotten to the point I wear them mainly on dates or when I want to impress people. Just like any white sneakers, they can easily get dirty. I would recommend buying a waterproof spray and spraying them a few times before use. They are also extremely comfortable! If I wasn't worried about them getting dirty, I would be wearing them all the time!

Fantastic shoe for casual wear or distance running
6 August 2020

I've owned this shoe for a little over a month now, and I don't think I'll want to try another running shoe for awhile. The design of the shoe is beautiful, as the gold really stands out. The stripes on the side look painted on, and are only slightly imperfect. It's hard to tell unless you look at the shoe very closely.The shoe is a little heavier than my previous running/casual shoe, the Nike Flyknits. The tradeoff is fair, because the sole of the shoe absorbs a lot of impact while distance running on sidewalks. And it is not excessive for everyday wear in the office.My only other complaint thus far is that the tongue of the shoe can flip and fold downward, obscuring the logo.

Favorite shoe I've ever owned
6 October 2020

I use my white pair of Ultra Boost's as a comfortable and stylish shoe for casual wear. I would wear running and hiking if I didn't care about them saying white although I think they would hold up very well in the wash if you wanted to wear them harder than I do. I own another black pair that I have used on 15 mile + hikes without any pain or damage. My black pair is my go to shoe that I have worn about 5 of every 7 days. The Continental rubber sole doesn't wear down like at all! The sizing has been accurate. I hope that Ultra Boost's stay around for a long time!

Fixed my foot problems
13 September 2020

I had some severe pain from metatasalgia, a nasty condition that is causes pain in the ball of your foot. Every step can feel like you are stepping on a sharp pebble that feels like its stuck in your shoe.I had been wearing Skechers. Comfy but little to no support. I saw my foot doctor and her recommend trying different shoes and wearing a hard orthodic for support.I had heard alot about the comfort of Ultraboost and thought it was just hype. It is not hype. Its not even close Ultraboost is by far the most comfortable and cushioned shoe I have ever worn. The support is also really good.

Nice shoe but the ankle fitting is poor. It's too tight
29 June 2020

Looks nice. Very light on feet, but feels comfortable only for about 5mins before it starts to hurt the front part of my ankle. It's so tight around my right ankle that I could feel my feet going numb. I use a size 8/8.5 in dress shoes but use a size 9 in athletic shoes and sneakers. For this pair, I actually bought a size 9.5 and it was still super tight on my ankles. It's ridiculous

Probably their best shoe!
24 September 2020

Between my son and I, we've bought four pairs this year. The 20's offer a little more toe-box room than the 19's with the updated design. I prefer the styles with colored Boost as opposed to white Boost because they just last longer. I wear them for running and casual wear. They fit a little snug with the liner, but I usually remove it because the Boost is cushy enough.

Trust the negative reviews
29 November 2020

If you take a time to look through the one-star reviews, you'll see that the shoes have a serious quality issue. Mine lasted less than 6 months. I don't know how Adidas can justify charging a consumer $150-plus dollars for shoes that fall apart. Don't waste your money. I used mine to walk in on sidewalks, and they detoriated in 5 and 1/2 months. Imagine running in these!They would last 3 months! I have Nikes from 2 years ago that have no issues. Again, it's just not worth it.

Ultra Comfortable exercise sneakers
22 January 2021

Now at a later stage in life, and with foot aches, this sneaker by far has allowed me to exercise without foot pain from leg exercises or enjoying the occasional soccer outing. I was worried that the side stitching would not last long, but the pattern makes it extra strong and durable and has not displayed any deterioration after a year of using the same sneaker for my gym visits. I own several other sneakers from Nike, but the comfort of these sneakers make it an easy decision to use the same sneaker to workout!
