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 our ocean. The other 50% of the yarn is recycled polyester.
