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.

I’ve loved the Adidas Ultraboost for years been a great sneaker for running but this style have a hard plastic near the lateral side of my arch and are extremely uncomfortable. Felt like my feet were bruised and I could not get an exchange.

Ultraboost 21 feels so light it’s perfect for runs walking and impact workouts. Moving feels effortless these are the best shoes I’ve ever had. I was a little sceptical with the knitted body if it will give enough support but it definitely does. The only reason I can’t give 5stars is the sizing. After reading heaps of reviews and most people advising the shoe runs small/tight and should opt for 1/2 size bigger. In my case that wasn’t needed and I’d say my foot is average width. But absolutely will recommend the ultraboost to everyone.

I got them after cheaping out at dfo on some random brand and they’re amazing been on a few runs and they give good bounce and super comfy. Didn’t really need to break them in and no blisters!

Decent running shoe, I tend to use these for walking instead. Definitely wouldn’t recommend for anyone running over 3-5km
Great running shoes for older feet as well as young ones. Love the mesh top very forgiving around odd shaped feet. Also the grip around the ankle is good.
Super comfortable, fit the foot amazing and didn’t have any pressure points like other reviews seem to say. Definitely worth the money. Have had ultraboosts for years and I think these ones may be my favourite
I took a chance with the sizing but fitted perfectly. I'm a size 5 shoe but always go for 5.5 size in trainers. I only run up to 3 times a week short distances of 5ks. So I can't comment about longer runs. But they do the job for me. Fit perfectly round my ankles.
Absolutely love all the ultra boost trainers. I buy a new pair every year & they keep on getting better & better! Perfect fit for running. May need to wear socks with these as the seam above the toes rubs a little.
I have now purchased three womens ultraboost shoes. I have found them all outstandingly comfortable, however , the last pair, the least comfortable of the three. I found that they come up slightly higher under my external ankle and rub on a long walk.
these are my 5th pair of ultraboosts in the last 10 years, they all last pretty well with daily excecise - walking and running outside - for around 2 years, comfy supportive and sturdy, good fit
