The Great Canadian Sox Company Ladies Wool Thermal

The J.B. Field's 40 Below Arctic Trail is one of the warmest thermal winter socks we make, containing 85% preshrunk wool! This style was designed for people who require a sock to keep their feet dry and warm in the most extreme conditions—as low as 40ºC! 

Pair these winter socks with a liner sock to help wick away moisture and keep your feet smelling fresher, feeling warmer, and blister-free.  

Pre-shrunk Wool: We use only the finest quality of easy-care wool in our socks because it is such a versatile fiber. It is breathable and moisture-wicking and helps regulate body temperature by keeping feet dry, preventing blisters, and controlling odor. 

PLEASE NOTE: These socks run large. We recommend wearing a liner or sizing down, if possible.
