The brand new Grippear Sock is a Crew length, heel & toe constructed sock with grip-enhancing Silicone added to the interior and exterior of the foot bed. The addition of Silicone grippers are intended to minimize movement of the foot in the wearers shoe and reduce friction at points of contact. These grippers will also increase the efficiency of your energy transfer when engaged in accelerated motion, making the Grippear sock great to use in any sport with frequent stop and go movement, repetitive planting and pivoting.
