adidas Ultraboost 21 Men's Grey/Core Black

Energize your runs in the adidas Ultraboost 21! This version takes all the aesthetic ingredients from the original and fuses them with the latest technology to provide comfort, support, and energy return. Step into a Primeknit upper that combines support and comfort to improve movement. Every stride on the Boost midsole provides a lively ride to move you forward. Adidas LEP torsion system increases forefoot bending stiffness for a more responsive run. When it comes to comfort and energy return, the adidas Ultraboost 21 reigns supreme!

What's New?

  • 6% more Boost capsules in the midsole provides the perfect mix of energy return and comfort.
  • Newly redesigned LEP torsion system provides runners with less flex in the forefoot and increased responsiveness.

Who's it for?

  • Neutral runners who crave a high-performance shoe that provides incredible responsiveness and ultimate comfort during short or long runs.
  • Fashion enthusiasts looking to improve their street style with a cool, comfortable shoe for casual use.

Great Shoes. Great Service!

Fit true to size. Very comfortable. I wear them not for running. But my hospital work shoe. Do the job as good as any shoe before! Great Service also!
