Nike's Dri-FITŪ Channel Cushion Crew is a soccer-specific sock with a dynamic arch bridge. This area of compression provides a comfortable fit and muscle support to help reduce foot fatigue. Built with an anatomical left and right design, these socks also include Dri-FIT fabrics that pull moisture away from the skin. The toe and heel are reinforced for extra durability, game after game. Even better, these sock colors hook up with the key cleat and shinguard colors of the season. Size M fits men's shoe size 6-8 and women's shoe size 6-10. 75% nylon/20% polyester/5% spandex. Imported.
