What do you get when you take a beloved running shoe and tweak it for everyday wear? The Ultraboost DNA. This iteration lives up to its namesake with BOOST for energy return and all-day comfort. The foot-hugging adidas PRIMEKNIT shows off contrasting weave details, making it a legend of its own. 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.
