Show up in style in shoes made to adapt with you. This reimagined adidas classic reinvents the relationship between style and technology. A sock-like upper makes for sublime comfort while a BOOST midsole supplies energy with every step. This shoe's upper is made with a high-performance yarn which contains at least 50% Parley Ocean Plastic â 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.
