I read the reviews and was a bit skeptical if these would work for me. Seemed to be hit or miss. I love them! I wear them to the gym. Haven't run in them but they are awesome. I usually wear 7.5 in running shoes and I probably could've used a 7. I ended keeping the 7.5 and ordered a 2nd pair.

I was a little iffy on buying these from the reviews but I did anyways! I LOVE these shoes, I am an Amazon delivery driver and as you can assume I am on my feet ALL day, I do a lot of walking (10,000+ steps a day roughly) so I decided against walking shoes and got running because of how much I do. I’m on day 3 at work of wearing all day, haven’t had to switch shoes while “breaking these in” I am in love with these! When I first got them I was a little hesitant about the fit (it was a little tight) but now they fit like a glove. Didn’t take much for these to break in at all! I also have plantar fasciitis and these seem to help a lot (so far) it’s hard to tell if it’s that or just being on feet all day!

Wow! Probably one of the more comfortable shoes I have ever bought. Since shoes companies are constantly changing their models, I plan to buy a few more of these babies to keep for the future. I purchased the white/white/gray. The gray is so light it appears white which is fine with me. You get what you pay for, and these are well worth the price tag.

Really enjoy these. Have been an Adidas fan for a while, good support and cushion for those that need both. After having plantar fasciitis off and on for 3 years, I'm very particular on support and cushion.

I use my sneakers for training only. I never have any adjustment issues. I wear a 7 but always purchase sneakers a half size larger for movement. I have several pairs and they are great.

I typically run Brooks Adrenaline or New Balance 860; yes stability shoes but I wanted to go back to some neutral shoes with high cushion and different brand; and a different ride. and I thought about Adidas because I’ve never really run in their shoes. (I used to work in a run speciality store) I usually wear a 10 in Brooks and New Balance but 10s were too big so 9.5 is perfect. I size up from normal street shoe size at a 9. I like nice 1/2 all the way around my foot so I have no contact in the toe box. Love running in these shoes. Feel so comfy and light; great energy return. Great support and the knit is tight without being too tight. I suspect it will stretch a bit thorough. The heel is high but doesn’t look funny when you wear them and the slight roll of the toe give a smooth transition. Putting together some higher mile training and I look forward to rotating these with some firmer racing flats and trail shoes.

Before this pair I had a UB19 sized 7.5. I have flat feet and the UB19 was the most comfy sneakers I had ever own, but the colour was really routine. So I attempted to add UB20 to my shelf but they turned out quite disappointing - a lot more rigid and less responsive than the 19 (not sure if it is the Running vs Women Running issue though). In the end I went with the UB21 whereas the Cloud White/Solar Yellow combo is just fabulous and the sole is eye-catching. I read the review carefully and ordered 1/2 size up to 8. It feels perfect the moment they are on and I just don't want to take them off even when walking around at home. They are not as soft as UB19 but definitely not at the sacrifice of the comfy level. Best pair of sneakers I've ever own!

Originally got 5.5 but fit too tight. So I went a size up and they fit like a dream. I’m obsessed with this pair.

Great look and feel. The fit is a nice, snug fit. Comfortable bounce and support. The knit around the ankle takes some breaking in, 2-4 wears should be enough and I recommend keeping the laces looser while you adjust.

These shoes are so comfortable but they do get dirty easily. I just got them and there is a tad bit of dirt of them on already. I did get them for a steal of a price though on Black Friday and they look very unique. I have never seen soles this thick and they will match a lot of outfits. I definitely recommend these shoes. I like that they come in a lot or colorways to choose from.

Like the look of the shoes but they definitely dig into your ankles as you’re wearing them in which the old ultraboosts have never done for me

Opening the box. I liked the style of this shoe, and I thought it would be a good fit. Unfortunately I found I could not get my foot into it. I have a high instep. I had to return them for this reason.

This shoe is really hard to get on, and the sole is big… it just looks huge but they fit true to size. It puts a pep in your step for sure. A comfortable shoe!

I have an older pair of these which were much more comfortable right from the start. I’m giving these a chance to break in. I like the colors.

This look awesome. I love the look and the color scheme. I like that they are soft against the back of my heels as I prefer no show socks. However, I am so disappointed to say, I will be sending them back because they come up too high on the sides hurting my ankles. Every step I take I can feel the sides digging in under my ankle. Bummer! These are cute. My search for running shoes continues.
