The Ultraboost isn't our first performance running shoe to hold appeal in the realm of fashion. It's just one of the most beloved. That's why we made the Ultraboost DNA Shoes, a lifestyle trainer built off the bones of its more technical namesake. The simplicity of the design shines a spotlight on the pattern of the adidas PRIMEKNIT. And because comfort's a non-negotiable, run or no run, BOOST offers incredible energy return in every step.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.
