The J.B. Field's 40 Below Arctic Trail is one of the warmest thermal 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. Pair these winter socks with a
liner sock to help wick away moisture and keep your feet feeling fresher, warmer, and blister-free.
Don't require the extra length and looking for a slipper version of these socks?
PLEASE NOTE: These socks run large. We recommend wearing a liner or sizing down, if possible. Due to the thickness of these socks we recommend having enough room in your boots
