These warmest thermal socks are designed specifically for extreme cold conditions. The double-layered winter thermal socks feature thick knit containing Australian Merino wool. Merino wool provides comfort, softness and an exceptional level of warmth without overheating the foot. The outer reinforced layer prevents an occurrence of callosities and ensures maximum endurance. The X-shaped zone ensures that the socks stay up on your feet. An ergonomic fit and flat knit toe seams prevent rubbing of sores and provide comfort.
