bata boots size 7r fits 10 white open to offers This listing is for a rare, collectible pair of vintage 1977 US Military Issue Extreme Cold Weather Vapor Barrier Boots affectionately known as "Bunny Boots". Manufactured by Bata. * These are genuine U.S. government-issue boots, specifically dated to March 22, 1977, as evidenced by internal markings (see photograph). * Originally developed for the Korean War, the "bunny" (white) version of these boots is rated for use in extreme cold, down to approximately -60°F (-51°C), providing unparalleled insulation. * The boots feature a unique construction of multiple seamless rubber layers sandwiching thick wool felt insulation, creating a vacuum barrier that locks in heat and keeps moisture out. * Air Pressure Valve: A distinctive feature is the air pressure valve located on the side of each boot, used to equalize pressure during high-altitude activities to prevent the boots from rupturing.
