These sneakers celebrate the "can-do" in all of us, with a nod to the 50th anniversary of Title IX, which gave women equal opportunity in sports. Rooted in running but flush with street-ready style, they're built for whatever your day brings. adidas PRIMEKNIT wraps the foot for a supportive fit that enhances movement. The BOOST midsole provides instant comfort and energy return with every step you take. 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.
