Designed with the iconic English fashion designer, Stella McCartney, the adidas Stella McCartney x UltraBoost Parley ‘Stone’ sneaker blends fashion with performance. Created in collaboration with Parley for the Oceans, the sneaker features a yarn upper—some of which is made with Parley Ocean Plastic, a material made from recycled waste that was captured before it could reach the ocean. The stylish runner is finished with a responsive Boost sole.
