Long-distance running sock - Endurance Racing Knee

This sock is designed to improve the feel and performance of long-distance runners. Progressive calf compression stabilizes the muscle and promotes recovery. The sock's construction around the foot is very thin and solid to maximize the foot's sensation with the soles and the ground. The 3 grip strips ensure high contact of the socks with the shoe soles. Synergy Fit socks are developed from our database of over 400,000 feet to enhance sole benefits, stability and feel.
