The Type A-6A was a high altitude flying boot typically issued to American bomber crews at the very end of World War II. Standardized by the Army Air Forces on August 5, 1945 the boot was a slight modification to the Type A-6 by providing a leather strap at the top to help keep it secure. The lower section of the boot was molded rubber with a waterproof leather upper with a shearling lining. The boot was typically worn over an electrically heated insert or standard issue low-quarter shoe.
