    • Best shoe ever worn
Size: 11.5 Color: Black/Black/Grey
Perhaps not the best shoe ever made, but it must be in the running, certainly the best shoe I've ever worn. Feels like walking on a cloud, and the fact that the Parley version is made from Ocean Plastic is a very reassuring bonus. I was put off by the styling at first, the bottom of the rear of the shoe looks a bit ugly to me, but it's worth it for the ultra comfort, and it helps to wear long pants and cover the rear of them a bit. My strongest point -- This is my second pair of Adidas Ultraboosts, and I still have the first pair from 2015. At the time of this review, it's mid-March 2022, and I still wear that first pair every. single. day. Semi-relevant to note that I do about a hundred flights of stairs per day for work, swapping between the two pairs mentioned. The durability is astounding, especially when combined with a bit of Gorilla Glue for the non-visible cracks on the underside. I hope to purchase a third pair soon, maybe a different color this time. Can't possibly recommend any product more highly. You'll find that it's worth it to spend a bit more money on shoes. ... show more

    • comfortable and great look
have a unique style, continental sole and boost technology coupled with the parley initiative to include recycled materials from plastics and waste recovered from the sea. I'm usually 10.5US but it was better for me to order 11US as they are a very snug fit.

    • Comfortable and look good
Size: 12 Color: Core Black/Beige Tone/Signal Green
They are very comfortable for walking and exercising, their color makes them very exclusive and they look great with many outfits.

    • It’s a great shoe really sticks to your foot.
Size: 10.5 Color: Orbit Green/Black/Acid Yellow
It has stretchy material that allows it to stick to your foot while still being able to wake up your toes freely.

    • Very comfortable
Size: 11 Color: Black/Black/Grey
Style works great since I use them at work. Durable in the Fresno heat. Grip is good since it uses continental material.

    • Size a half up from your regular size & these shoes are sick!
I always wanted a pair of ultraboosts 21 and found this pair on sale. Purchase it in my regular size and a half-size up. The fabric is not flexible from what I've read with these recycled shoe products, so a half-size-up may be necessary for a better fit. My research was not wrong so I kept the bigger size and wear these shoes often. These shoes feel GREAT on my feet. Nice support and great cushion with each step. It's not too soft, like NMDs, and not too rigid, like cheaper shoes. These are all around great daily wear and exercise wear. ... show more
