Warm wool socks for men in gray with elegant block pattern. They are made of pure sheep’s wool. Great gift for birthday or holidays! These wool socks are thick, soft and super warm! Wool is an ideal fabric in socks because of its naturally wicking and warming properties. These thick wool socks are ideal for rubber boots or large work boots. Ideal if you work outside or in cold storage a lot. Very popular with people with rheumatism and arthritis complaints or winter toes. Wool fibers trap air so that a microclimate forms around your foot. This provides ideal combination of insulation and ventilation!
