X-Socks Winter Run 4.0 Socks, zwart

Warm feet even in bone-chilling cold. That's what the X-SOCKS 4.0 WINTER RUN with highly insulating high-quality Apani Merino wool makes possible. Equipped with the patented Lambertz-Nicholson Achilles Tendon Protector 4.0 your archilles tendon is protected from pressure and friction, decreasing the risk of injury. The X-SOCKS 4.0 WINTER RUN socks keep you pleasantly warm, but they also protect a distance runner's foot from blisters and chafing because dry skin is more resistant to friction pressure.

Lambertz-Nicholson Achilles tendon protector
With its highly abrasion-resistant and shock-absorbing material, it protects the Achilles tendon from pressure points and friction caused by the edge of the shoe. The sensitive Achilles tendon is not stressed as it lies embedded in the opening of the pad.
