The operating principle of gradual compression is simple, yet highly effective: these high-tech, knee-length socks accelerate the transport of venous blood back to the heart. Not only does their gentle compression stabilize the tendons and muscles, it also optimizes the supply of nutrients to the muscles. The wearers movements become more precise and the exhausting muscle quivering produced by muscle fatigue is contained. Trekkers can use the X-Socks® Trekking Energizer to enhance their performance and reduce the risk of injuries. These socks help counteract muscle pain, thrombosis and performance loss.
