Monochrome sock-like fit trainers made from recycled materials from adidas by Stella McCartney.

This ultra-leighweight, all-black pair of trainers from Adidas by Stella McCartney are classic, but anything but boring: the ultra cushioned Ultraboost soles are designed to keep you running more comfortably and feature a white logo tab for a little monochrome contrast, making these the perfect gym-to-street crossover sneakers. 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.

The Ultraboost 20 trainers are designed with a unique boost technology for ultra cushioning, with superior 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 a casual streetstyle look.
