Performance running shoes made in part with Parley Ocean Plastic. With sock-like adidas Primeknit upper that is even more breathable than before, these adidas Ultraboost running shoes are the new stars of the track and treadmill. A moulded heel counter supports the back of your foot, while adidas BOOST feels responsive and comfortable over long distances. The Stretchweb outsole is made with Continental™ Rubber for impressive traction and a smooth ride. 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.
