Every year, adidas’ Ultraboost takes another step into the future of sneaker innovation, and this is 2021’s version. It’s got all the features that make the runner an icon, but dialled up a level. The knit upper contains Primeblue — a yarn derived from plastic ocean waste — while the wedged boost™ cushioning pairs with all-new Torsion tech for energy return like never before.
