  • Pretty good
Size: 10 Color: Black/Black/Black
Takes some time to adjust lol but definitely good comfort I work at an airport and stand on my feet all day , my heels were killing me for sure this took away all the sharp pains for sure just make sure to not wear any thick socks in this shoe for they have a good form for sure but they can be tight and order half size up for sure ... show more

  • Good running/walking shoes
Size: 6 Color: Ash Pearl/White/Halo Ivory
These shoes provide great support for running and walking. The heel is a little ridiculously large and looks funny when worn with shorts. I see the functionality of the large heels, though, because they are easy to slip off. The shoe hugs the feet, which I am not necessarily a fan of. The laces are mostly decorative, basically. I love the rose color I chose and get compliments on them. They aren't the best for working out as far as sitting for stretches because of the large, protruding heel; but the work-out itself is fine in these shoes, as they provide lots of support and shock absorbency. ... show more

  • Had to get a size 5 when sizing chart said 6
Size: 5 Color: White/Black/Solar Yellow
They fit large. You might have to return for another size. Sizing chart said I was size 6, but I had to return twice as I ended up with a 5 that still fits a bit too large.

  • 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

  • I bought the right one!
Size: 5 Color: Black/White/Violet Tone
Except for the slightly tight entrance of the shoes, everything is fine. It's very beautiful, the feet are light, and there is a sense of help when running. In short, I like this pair of shoes very much.

  • 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
