Run, balance or pivot — every movement is effortless in these adidas running shoes. The adidas Ultraboost Shoes are engineered for excellence, from the adidas PRIMEKNIT upper that gently wraps your foot to responsive BOOST. A Stretchweb outsole made with Continental Rubber takes bumpy terrain in stride, while a supportive heel counter supports fragile areas just below the ankle. 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.
