But this pair is also made to celebrate your love of sport. Bright colors are borrowed from soccer team colors — a celebration that you can wear on the sidelines or out in the city. BOOST cushioning keeps your feet comfortable, whether you're cheering your heart out or going about your day.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.
