Size: 8 Color: Black/Black/Grey
I run and I have Adidas, Asics, Hoka. I have to say Adidas fits your feet like a glove. It hugs your feet. That's what I notice about this shoe. It's heavier than Hokas. Hoka are light weight. Adidas is more "huggy" and snug. I wear between 7.5 to an 8. I got an 8 on this and it's perfect! I would buy this shoe again if I had to. ... show more

    • Ultraboost!
Size: 7 Color: Black/Black/Black
I have several (a lot!) pair of Ultraboost. To me, they are the best, most comfortable athletic shoes I have ever worn and I only wear Ultraboost now. But I will say, these are not as comfortable as many of my others. They are less flexible. They still offer great support, but I prefer the shoes that are mostly (or all) the mesh material on the upper around the front toe half of the shoe. It just offers greater flexibility to me, which I feel is more comfortable. Still love this shoe, and it offers great support and reduces fatigue from a long day on my feet. I highly recommend the Ultraboost series for anyone looking for a great supportive shoe, especially when on your feet for hours a day. The only other shoe I’ve found comparable for extended comfort and support is Timberland Pros. ... show more

    • I love these shoes so much!
Size: 7.5 Color: Tie Dye
I’m a nurse and usually a sketchers person, but I feel they wear out pretty fast and then the Hokas are great, but not cost effective. These are both durable and affordable. They also offer a lot of support to my arches and the extra sole padding on the bottom of the shoe makes it much more comfortable when on your feet all night. ... show more

    • Runs big😩
Size: 9 Color: Shift Pink/Shift Pink/Rose Tone
Is it me or do these shoes run big? As soon as I put them on, I noticed there’s a big gap between the back of the shoe & my Achilles. Plus, there’s a lot of toe space. Much more than I’ve ever had for a pair of sneakers in my shoe size. I like the color, but I’m debating whether or not to return these sneakers since they’re so big. I am disappointed. ... show more

    • Better than I was led to believe
Size: 12 Color: Black/White/Violet Tone
The shoes fit OK, much better than the lower star reviews I have read. I bought these as a “transition” into the ultra boost brand of shoes. As of now my only criticism is the shoe laces. Looks much better with blue laces as opposed to brown/tan laces that came with the shoes.
