Caring for the environment never looked (or felt) so good. Support your fitness goals while you support the planet with the Ultraboost 20, the latest incarnation of our most famous running silhouette that was designed and tested for 10 km runs. The urban running shoe's upper was created using Primeblue. This recycled high-performance material, made in part with Parley Ocean Plastic, is just part of our commitment to continue to innovate in the area of sustainability until we reach our goal of being completely off virgin polyester by 2024. Woven with Primeknit for breathable support and sock-like comfort and set on the uniquely responsive Boost midsole, your feet will feel as light as your conscience does when you slip them on. The all-black colorway means they'll go with all your workout gear too.
