This lightweight sock improves circulatory function by forcing the blood from your feet back up to your heart, while flushing out lactic acid. Additionally, muscle containment offers relief to pulled calf muscles. Ideal for travel and the long drive home after a race. Features padding for the heels, toes and balls of foot with vented toe panels for maximum breathability.
