The Ultraboost 20 is as high performance as it is stylish, and will look as good in the gym as they would as part of your everyday wardrobe. The yellow base is contrasted with green and black knitted into the design. This shoe doesn't just look good, but does good too: these shoes are made with Primeblue, a high-performance recycled material made in part with Parley Ocean Plastic - 75% of the textile upper is Primeblue yarn, no virgin polyester is used.

Designed with a unique boost technology for ultra cushioning, with superior cushioned stability and energy: the more energy you give, the more you get. The knitted seamless upper is engineered to fit, expand and support as you move.

Perfect for running, the gym or teamed with your favourite jeans for the ultimate retro look.
