GUC Supportive and cushioned, the adidas Ultraboost is great for daily wear. The foot-hugging adidas PRIMEKNIT upper offers a snug fit while BOOST cushioning delivers instant comfort with each step. These sneakers feature an innovative Torsion System for added stability, whether you're running around the park or just running errands. 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.
