The Interval running compression socks are mid-calf socks made of high-tech polyester fabric that makes them light, malleable, tear-resistant, and quick-drying. These running socks with arch support are designed to protect your feet even on the most arduous runs. They feature anti-twist support bands, Achilles tendon shock absorber, and proprioceptive compression that gradually exerts compression on the foot. The shock absorber helps prevent pain from foot strike, while the graduated compression exerted on the foot helps with proprioceptive control of the ankle joint.
