Customer Reviews adidas Ultraboost 21

Order at least a 1/2 size down. i recently purchased my second pair, these are excellent walking shoes.

I am a long-term ultraboost fan. Got a pair for my 90 year old grandma and she loved. It’s the ultimate approval!

Great shoes. Fits as advertised. No flaws. Would happily buy them again.

Love the shoe lots of cushion and support.

Perfect on all accounts!

I’m a super Ultraboost fan. They’re comfortable, provide amazing support and look nice and sleek on my feet!

These shoes are amazing. I was skeptical that they would live up to the hype. For years I've been a Brook's girl, and wasn't sure any other shoe would live up to their high standards. Very pleased with the great support these shoes offer!

Overall great fitting running sneakers. Definitely recommend both of them!

This shoe gives me more pep to my step because boost has more bounce than react foam (my previous runners).

The fit was great, but they made my feet look enormous!! I couldn’t bear to look down on such gun boats. Sadly, they were returned.

Very good I like it better than UB20

I Love these sneakers they are very comfortable , I wear a size 9 and I brought my correct size and they fit very good. The color is amazing the bright lime green accent adds an extra pop to them. The width is good not too wide. All around very comfortable sneaker and I would recommend them.

Great shoe! Comfy and stylish. I’m normally an 8.5 and I got them in 8 and 8.5. I like to run in a more snug shoe and wear them looser for more casual wear.

Love love love these shoes. Bought the Boos Stripes and love the Hazy green color. So comfortable and the best workout shoes.

Larger then normal

The Ultraboost 21 offers a new spin on a new-ish classic from Adidas. Although the 21s run a half-size smaller than all of my other Ultraboosts (DNA 2.0, 4.0, 19, and 20)—but also true to my size in other brands—they are wonderful when you find the right size. My minor complaint is that the toe box is more shallow than other Ultraboosts and sneakers from other brands. It’s not unbearable, but it is slightly noticeable. Otherwise, these are great shoes that are comfortable and fun.

I walk outdoors for several hours every day and I need supportive shoes. These are very comfortable to walk in. They seem to absorb impact very well and they have good, moderate arch support, which is fine for me. They’re also easy to slide on and off.

These are high quality, good-feeling, amazing shoes!

Great shoe and even better value.

Love these! Good fit & great style!

I’m an asic kayano lover but wanted to try something new. These did NOT disappoint! Super comfortable, stable, light weight. These ran a full size big for me in asic I’m a 9 but in all regular shoes I’m an 8. So aster seeing these fit generous i ordered an 8 and I’ve got just enough room. Highly recommend

most comfortable sneaker for wearing

They're exceptionally cushion-y & make my old running shoes feel "flat." I'm thinking about another pair in a different (but universal) color like black to go w my workout gear. Great running shoes, I can't go back to anything else.

Super comfy and looks stylish and not at all. basic! Wear with joggers, jumpsuits and dresses. True to size
