They meet what is expected
TonyRH - 03/12/2021
Comfortable and good quality shoes, as is known, are somewhat heavy, a reduction in weight would be appreciated without penalizing the cushioning. They look good quality and good finish. Maybe a bit narrow but not excessively, at least for my foot. The lacing is well thought out, despite being made of plastic, it holds the lacing and does not slip when you are tying, which is useful, although on occasion it tends to over-tighten in the lower part of the foot if you are not careful.

Perfect sneaker
AAA93 - 03/12/2021
It seems to me the best shoe on the market, also adapting to other sports than running. In my case, its use has favored my recovery from severe sciatica pain. It adapts perfectly to the foot.
originally published on adidas
I love them but if you were a fan of the ultraboost 19 like me, the 21 are different and my little finger hurt with hardly any use, so they don't suit me.

Disappointment
Ann75 - 03/12/2021
Years using adidas, and the ultraboost I did not change for anything, I was a bit disappointed not to feel as comfortable the 21, narrower even point of discomfort after the training session.

Delivery on time. shoe color suitable for 'urban' use. perfect adjustment
Chemical - 03/12/2021
I still have my ULTRABOOST 21s in the “break-in” phase and use them as “urban footwear”. Logically very comfortable. They fit a little less, which has been very good for me since it was between two sizes of the usual Adidas last. The fit is perfect and the laces are almost a complement. The back of the sole is a bit "weird" initially, but it promises improved cushioning, for those of us who need it. Despite announcing a delay in delivery, it was finally corrected, which was practically immediate, as always.

Evolution
BPyL - 03/12/2021
I'm a regular long-distance runner, about 70kg, and compared to the 2020 ultraboost, the 2021 ones are -Header (but you get used to it quickly) -They have more incline -They have more boost -I have improved some discomfort in the achilles (to whom I can serve, there I leave it) In summary I would not return at 2020.

Good design, comfortable, the issue of sizes is not clear.

Much better than i expected
Innombrable30 - 03/12/2021
The shoes have been a gift for my husband, so here I review his verbatim words about the shoes: “They are fantastic, I really wanted to have them and they have surprised me for good. They are more comfortable than I expected, they have a spectacular grip, with each step you feel the momentum back. Without a doubt the best I've had so far ”I can say that buying from Adidas is a pleasure, fast, comfortable and without any problem, neither in the purchase nor in the delivery.

Sizing too large compared to the ultraboost 20
Haxo - 02/12/2021
I bought one size less because the change in size from one model to another is excessive. Drop too sharp. Except for these details, I am very satisfied with the quality of the shoe.
