These women's running shoes are built for all-day wear. The upper is made of foot-hugging adidas Primeknit with a translucent cage and faded backside print. Boost gives you energy return for total comfort and a Stretchweb rubber outsole flexes naturally for an energised ride. 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 the ocean. The other 50% of the yarn is recycled polyester.
