An update on our most iconic running silhouette.

The adidas by Stella McCartney Ultraboost 20 Shoe might boast a retro style, but they're actually a high-performance update on our most famous running silhouette. In great news for feet everywhere, they were designed and tested to be comfortably worn on your next 10km run. The 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 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. Easily incorporate the shoes into your everyday wardrobe thanks to their on-trend colour palette. Vintage jeans and an oversize button-up white shirt make for a nonchalant yet fun streetwear look. Not that you need any help in the style department, of course.
