Since 2005, British fashion designer Stella McCartney has collaborated with adidas to bring her design sense to the world of running. These adidas by Stella McCartney UltraBOOST X Shoes feature a sock-like adidas Primeknit upper for adaptive, strategic support. A free-floating arch hugs your foot, allowing it to move and flex naturally. The upper is built with recycled yarn and features a mlange knit that's pure Stella.
