There’s a Reason this Sock is called 40 Below
This fully cushioned thermal boot sock was designed to keep feet warm in the coldest temperatures. Appropriately named "40 Below", the sock is amazingly comfortable and warm. The nylon/wool blend is soft against your skin. Designed to trap air for heat retention and breathability even when wet. The smooth toe closure is an added benefit. A quality sock that is made for all day comfort at work or in the field.
Made of 50% Wool, 48% Nylon, 2% Spandex for stretch and resiliency. Large fits men’s shoe sizes 9-12, X-Large fits men’s shoe sizes 12-15.
