Why should runners get all the best shoes? We asked the same question and came up with an answer — the Ultraboost DNA. It has all the features of one of our most popular performance runners, but it's made for wearing every day, everywhere. Lightweight adidas PRIMEKNIT hugs your foot for ultimate comfort, and midsole BOOST returns energy with every step wherever your two feet take you. 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.
