The Ultraboost was born as a high-performance running shoe, but this pair was created as an everyday shoe. Because comfort and style this good? It shouldn't be confined to the track. Head out and enjoy the responsive feel of Boost cushioning and the soft hug of adidas Primeknit. The corduroy overlays are all about the style points. This product is made with Primeblue, a high-performance recycled material made in part with Parley Ocean Plastic.
