X-Socks Run Performance Socks Twin Pack

Run Performance has little energy boosters for your feet. All anatomically vulnerable zones are padded, reducing the chances of blisters and pressure sores, even during long periods or intense activity.
Air-Dens™HD padding system, cushions impact and reduces pressure on the balls of the feet, toes and heels. The AFP™ system protects the foot in the shoe, stabilizes the ankle and provides an optimum interface for the transmission of impulses from the shoe to the foot - without constricting movement.
The heel-to-toe motion is gentler and smoother. The temperature-regulating Air-Conditioning Channel® and composite yarns quickly absorb moisture from the skin and carry it to the surface, thus, reducing the risk of blisters. To ensure that the padding is in just the right place and the socks fit perfectly, they are marked "L" for the left foot, and "R" for the right.
