No matter how far your run is taking you, these adidas by Stella McCartney shoes support every step along the way. With their ultra-light and adaptable design, another block or another mile (maybe make it two) doesn't feel impossible. In fact, with the plush BOOST cushioning matching the energy you're throwing down, it's almost effortless. This shoe's upper is made with a high-performance yarn which contains at least 50% Parley Ocean Plastic — reimagined plastic waste, intercepted on remote islands, beaches, coastal communities and shorelines, preventing it from polluting our ocean. The other 50% of the yarn is recycled polyester.
