The SockGuy SGX6 Three Amigos Socks feature Sockguy's Elite Performance Formula fabric, which is a soft and moisture wicking blend of polypropylene, nylon, and spandex meant to keep your feet dry and chafe-free on even the warmest of days. The six-inch cuff incorporates compression ribbing for a bit of extra support while remaining within current sock height trends while a fitted arch provides midfoot support and eliminates uncomfortable bunching and mesh paneling across the top of the foot increases ventilation. As an added bonus, SockGuy adds reinforcement at the heel and toes to increase durability.
