A heavyweight thick sock especially designed for keeping feet warm in extreme conditions. Fine merino wool has been used to create a very soft thick inner wool cushion sole, foot and leg to keep feet warm while a nylon outer layer keeps that warmth locked in and ensures long life. Non-slip elastic sections around the foot reduce friction between the sock and the boot.
