adidas x Parley for the Oceans team up to drive awareness with these running shoes. The precisely positioned adidas 4D FWD midsole guides your feet forward and reduces impacts for a smooth ride. The Stretchweb outsole expands with each stride for confidence-building traction.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.
