Run to feel good. Feel good about your run. These adidas Ultraboost running shoes are made with recycled materials as a part of adidas’ commitment to help end plastic waste. Lace in and hit the pavement knowing that every step is a part of that meaningful journey. And if your daily miles are met with sunkissed pavement and blue skies? Their energy-returning Boost midsole pops more than ever, thanks to a UV reactive effect that changes hue on sunny days. 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.
