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 lifestyle appeal, 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. 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.
