Customer Reviews adidas Ultraboost 21

Love these shoes

The feel of the shoe in hand and the weight, truly a quality pair of sneakers from Adidas! Bravo!

I normally wear size 9.5 and add 1/2 size for sneaker shoes. I ordered size 10 and it feels great. The design enable to wear the shoes easily just like wearing loafer model. The tongue material is soft and comfortable; fully integrated with the shoes body. Zappos price is unbeatable. Great customer service. Highly recommended!

There so comfortable and fit perfect. Love them.

Just one think Beautiful shoes from adidas and good price

Feels comfortable on feet

Super comfy shoes, order a half size bigger than normal. Great for everyday use.

I thought the pictures online were a bit off, but I was wrong, these are amazing. They give off a “fire red” vibe Zappos delivered 2 days earlier than expected. Thank you SO MUCH Zappos The ultra boost 21 is better than the 20 for the reinforcement around the base of the boost soles. My ultra boost 20’s wrecked when running outdoors but this here is a marathon runners dream. The super plush boost on the heels are going to be a PLEASURE when standing in long lines on Black Friday ( once again thank you Zappos; you legend!) and Christmas shopping, and even better on airplanes when your feet and toes get “smushed and sweaty” on other shoes, the breathable sock like layer on top is super cool if you have for instance those floor air conditioners on your cars, your toes will legit get a slight breeze of cool air because the material is so breathable. In summary stripes> checks Zappos is the thanksgiving day GOAT, real?? in a bottle delivery.

very stury and supportive, unlike r1s.

Got these for my son, an 8th grader. He loves them! It’s actually his second or third pair.

Great shoe for my 14-year-old son. They have a pretty thick heel, which he likes because they make him look taller

The first pair were very tight, enough to feel like they were hampering circulation. I had to order a half size larger. These are great. The sock-like fit is very comfortable. After removal of the insert, my thin orthotics fit well.

The fit was great!

Great price, great shoe

The shoes were great but didn’t fit so returned. ZAPPOS was excellent in giving refund immediately after the package was recognized at shipped/returned to them. Wish ALL companies operated that way! Adidas is ten times better than Nike products

Very comfortable for all-day wear. A bit too heavy to be a performance shoe. Love the look!

These fit perfectly, and right out of the box were extremely comfortable (probably the most comfortable shoes I have ever worn)

Very Comfortable sneakers
