The below design then is intended to better insulate the feet during inclement weather. The socks may be embedded with electric resistors between the inner cotton sock and the outer wool liners to then heat the socks to prevent frostbite.The flexible waterproof coating encapsulates the sock then mated to the outer lining.The air pump,one way valve and flow tubes are then placed between the two socks. The air pump has a plastic memory to then expanded position ( air intake ) and ventilates the toes.
