  • Fit comfortably first time worn out of the box.
Size: 5.5 Color: Halo Silver/Ice Purple/Rose Tone
Love the fit and comfort of this shoe. No historical struggle finding the "perfect" sock like Goldilocks Easy to tie for comfort. (and keep tied). Feels like I'm walking on sunshine. The struggle to find quality, comfortable, athletic shoes , with a smaller than average womans shoe size (5 -5.5), is real! I think I've finally found a great shoe. Yay. Thank you, Adidas. Your new customer for life <3 ... show more

  • They are fine.
Size: 8 Color: Black/Black/Grey
Not the perfect replacement for my favorite adidas. But they’ll do. I use them as a regular shoe. Not working out. And I don’t think they would be great for running. The shape of the heel feels like it pushes my foot to the front of the shoe. I’m hoping as they break in more that’s less noticeable.

  • Not perfect
Size: 7.5 Color: Grey/Grey/Screaming Orange
I am a long time wearer of the ultraboost, in fact I have a few older pairs that I’m stubbornly trying to keep alive. This version dropped the ball a bit. They made them too tight, to the point that anything over 2 to 3 miles, walking or running, & my left toes are being smooshed by the top of the shoe. It does not happen with the right shoe. This model also makes my feet sweat like they’ve never done in the other older pairs. The inlet is also insanely small! I have high arches and had to loosen all of the laces in order to actually fit my foot in. If you asked before I wore them I would’ve said they were great. The boost foam is magical to run on, but this pair is just okay bc of the discomfort they add. Bummed. ... show more
