The adidas Ultraboost shoes debuted in 2015, and they became a go-to far beyond the realm of running. For good reason. The adidas Primeknit upper wraps the foot in support, adapting to the changing shape of your foot with each take-off and landing. Plush Boost cushioning returns energy with each stride. 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.
