RUN PERFORMANCE 4.0 OPAL BLACK/ARCTIC WHITE

The RUN PERFORMANCE 4.0 from X-Socks is a high-performance trail sock for men.

Lightweight and soft, this technical model features targeted reinforcement zones that reduce the risk of heating and injury during prolonged efforts. A heel tab prevents the sock from slipping inside the shoe. In addition to Air-Conditioning Channel 4.0 technology for ventilation, an Achilles tendon protector enhances comfort. Another differentiating feature is the Pull-On Non-Slip Flap at the heel, which prevents the sock from slipping inside the shoe.

Finally, a 360-degree Albedo reflector enhances visibility and safety in the dark.
