The design features of the M-Tac high sock include special thermal zones and shock absorption zones in the forefoot and heel with a transition to the instep, protecting the ankle from sprains and mechanical stress. To improve performance during intense walking, a lateral arch clamp has been added to prevent the sock from creasing at the bottom. The wide cuff evenly distributes the load to keep the sock on your shin. The entire surface of the foot is lined with an internal terry weave that evenly distributes the load over the entire foot. Trekking socks with textured thermal zones absorb most of the moisture and through the existing ventilation channels, capillary remove the moisture through the upper of the shoe. In addition, they combine perfectly with membrane boots, as the process of transporting moisture to the outside is even faster. Material:75% COTTON20% POLYAMIDE5% ELASTANE
