Lightweight Insulated Footwear

Abstract

Compound formulations having good low temperature flexibility were developed for the outsole, upper and outer skin of the lightweight, insulated boot. The proper insulation thickness for the entire boot was determined from foot insulation test data to produce a boot having sufficient overall insulation. In an attempt to improve traction, a Vibram type outsole design was used. Susceptibility to puncture from ground objects was reduced by redesign of the outsole, and by spraying a thicker outer skin at the base of the boot. The ankle portion of the last was redesigned to provide a snugger fit and eliminate slippage at the heel while walking. A nylon sock lining to permit ease of donning and doffing was developed.
