An agreeably long, warm woolen sock, ideal for people wearing boots. Through the combination of virgin wool and pro-cool, the feet remain warm and dry in all conditions. The Thermo ML has many supportive and protective zones, plus an extra-long band to prevent sagging. The antibacterial fibres keep unpleasant smells at bay. The special zones on the sock provide extra protection for the heel and toes as well as comfort for the legs.
