TRUSOX Crew Length Sock - Thin. As seen on some of the best players in the Premier League, TRUSOX offer more control and in-shoe stability. Thanks to grippers on the inside and outside of the sock, feet are locked into the shoe and make for easier change of direction and shot control.If you want to wear TRUSOX with your actual team sock, use the Crew Length. For match play when a team sock is required, players at all levels can simply cut the foot out of their team sock. Then wear the team sock as a leg sleeve over their TRUSOX Crew Sock. Some use tape as a final step, but it's not required.60/38/1 nylon/cotton/spandex.
