Adidas added more Boost to the Ultraboost 21 Running Shoe to give us maximum cushioning and effortless energy return. The twenty iterations before this version were already incredibly comfortable, but the extra foam and fresh upper feel like a whole new dream. The supportive, mostly-mesh upper grants a secure fit that's intended for comfort through the miles.

Feels great, & ordered a half size up because of wider feet. With the half size up, fits perfectly!

I got a great deal on these! I've been in love with the '19 and '20 model, and these aren't quite the same fit. However, I wear them for my workouts almost everyday and they do the trick.

Bought two pair of trainers ASICS gel Kayano which fit perfectly but had to return the Adidas ultra boost as were a bit tight .Sent back and ordered a half size up and they arrived four days later so very happy .
Adidas Ultraboost 20's are still my favorite shoe. But I love how the 21's have upgraded the support in the sole, and have tilted the shoe forward a bit to really propel you forward.
Nice looking shoe, but the plastic lacing cinch rubs the top of the foot. Not a good shoe for my wife - needs more comfort.
I have always loved the adidas UltraBoost shoes so were very excited to try the new 21s out. I was not disappointed! Super responsive and super comfy
I love these shoes! The match most everything and are very comfortable!
