One of the Warmest Military Boots Available! Made of Rugged Rubber Thick Felt Liners Seal Out Moisture & Cold Air Rated to -20 Fahrenheit! Genuine US Government Surplus Brand New Side Valve Allows for Inflation or Deflation Depending Upon Requirements Also Known as VB (Vapor Barrier) Boots These boots, used by the U.S. Military in cold weather operations, are almost legendary for their ability to keep feet warm in extreme cold environments. Outside the military, these boots are popular with oil field workers, construction workers and others who work in cold environments. The boots should be worn with one pair of nylon/cotton/wool socks. The boots can cause trenchfoot and it is recommended that socks be changed up to three times a day as the socks will get wet from perspiration. (Socks can be dried by placing inside clothing next to the body.) Also, the inside of the boots should be wiped dry at least once a day.
