Warm, protective, and optimally climate-regulated. Specially designed padding zones make this merino sock the right choice for stiffer mountain and trekking shoes. With the special X-SOCKS® refinement, the unique comfort of merino wool is preserved, while significantly reducing the main disadvantage of wool (moisture absorption) – the perfect combination of "nature plus function." The patented Suppronation XX-Cross® bandage provides maximum stability, while ventilation systems ensure dry feet, and insulation chambers on the instep prevent cooling. Perfect for cooler days and tours in slightly higher altitudes.
