When the Ultraboost first dropped in 2015, no one had seen anything like it. Responsive Boost cushioning and adidas Primeknit changed the game in running comfort. That's why we made this pair to pay tribute to the OG construction in a version served up for your daily moves. Busy days and nights out dancing have never felt so comfortable. This product is made with Primeblue, a high-performance recycled material made in part with Parley Ocean Plastic. 50% of the upper is textile, 75% of the textile is Primeblue yarn. No virgin polyester. It is also made with Continental™ Better Rubber, an innovative, sustainable compound made from 70% natural rubber, 20% virgin rubber and 10% conventional rubber.
