  • Excellent Shoe - My Wife Loves It
Size: 8.5 Color: Grey/Grey/Grey
These shoes were on sale for a huge discount during Christmas. My wife is working on upping her running game and so I wanted to give her some shoe options. Normally, we buy Asics but since this model had so many positive reviews I felt like it would be worth it to give it a try, especially at the hugely discounted price. These have a dramatically different design style than the shoes she was used to. She immediately noticed that they were heavier than her other running shoes. But, after wearing them for a couple of runs and to work, she fell in love with them. Now, they are pretty much her favorite pair of running shoes that she has (out of 4 pairs). She wears a size 8 shoe but runs in an 8.5. These were a perfect fit. I'm so happy that she loves them and so I can definitely recommend them to others. ... show more

  • Highly recommend
Size: 9.5 Color: Grey/Grey/Grey
I wish the Ultraboost 21 were lighter because I did like the feel of them and the form-fitting upper. The upper part of the sneaker is thick and is designed to be more like a sock, which I like. It stretches to form around your foot. I would not say this is a high-volume shoe, but it easily molds to fit your foot in a very comfortable fashion. There is one challenge, if your socks are not super tight or are too thick, it's very easy for them to bunch up. The heel itself is very flexible and provides a tab to help pull the shoe on. I do admit that there are times where I'm struggling to slide my foot inside of the sneaker and that's when I wish I had the actual loop but at least there’s something built into the design. Overall, I have has nothing but an amazing and comfortable experience with this specific style. ... show more

  • Lightweight shoes to excercise
Size: 11 Color: White/White/Black
Didn't expect that women shoes would fit so good to me as a man. These shoes are really light and very confortable to either walk or run for excercise. Would recomend to buy them.

  • Comfortable shoe
Size: 8 Color: Grey/Grey/Screaming Orange
I normally wear Adidas Ultraboost but I accidentally ordered the running version. These shoes are very comfortable. I wear them for work which involves a lot of walking and on occasion some short distance running. I don’t run or work out on them but for what I wear them for they are nice. While walking quickly thought the halls of a hospital the plastic on the heels can be quite loud… but that could in part be how I walk not sure. ... show more

  • Love this shoe
Size: 10 Color: Black/Black/Grey
I love the style of shoe and I also love that on Amazon’s website it is 10 times cheaper. This is a great option for every day use or walking. I wouldn’t recommend this to lift weights or do any heavy HIIT workouts. I noticed on one of my shoes the inside sole rides up the back. I eventually had to superglue both of my soles down on the inside of my shoes. ... show more

  • Awesome!
Size: 6 Color: Black/Black/Grey
This is a comfortable shoe, one that looks good and seems very durable. Can't beat the price for a well known brand of shoe!

  • Shock absorbing, little big snug.
Size: 9 Color: Black/White/Violet Tone
I love that they don't rub my heel, but they are a little snug. The sole is amazingly super shock absorbent which I love and need for work! Get so many compliments too ☺️
