The reinforced terry-padded sole prevents pressure marks and blisters, absorbs shocks and helps increase endurance during extreme exertion and stress in everyday use. The elastic zone on the instep of the sock keeps it in place. Cotton socks are pleasant to the touch and absorb moisture well. The added FILACTIVE® functional material is a yarn composed of cotton and Meraklon polypropylene fibres, which is wear-resistant, has good thermal insulation properties and wicks moisture away excellently. The higher cuff is soft and does not constrict or tighten. VoXX® breathable socks in temperature class B can be worn in colder weather at temperatures from -5°C to +20°C.
