The X-Bionic Precuperation socks use Partialkompression to help athletes prepare for upcoming physical activity. After exertion, the socks stimulate circulation, accelerate the removal of lactate and optimise nutrient supplies. The ridges on the inside apply Partialkompression without impeding the blood circulation of the skin, while the black surfaces on the shaft simultaneously massage the athlete’s ligaments. Optimal placement of the sock is indicated by the PositioningLine on the shin.
