Anatomical shaping for the left and right foot keeps your feet comfortable even during strenuous and prolonged movement. Filactive® material combines the advantages of cotton with the durability of Meraklon polypropylene, has excellent thermal insulation properties, wicks away moisture well and resists wear and tear. The foot is reinforced, the hem is soft and non-constricting, and the construction wicks sweat away from the skin. The socks are in temperature class B from -5°C to +20°C and are also available in oversized sizes.
