Lightweight (Cold-Dry) Insulated Footwear

Abstract

An upper boot foam and outsole foam are developed for a non- discoloring, cold-dry, off-white combat boot. The urethane foam used is flexible down to -45 F, closed-cell, and lighweight. Computerized studies are conducted to evaluate materials (polyols, isocyanates, and chain extenders) and formulations. To fabricate the boot parts, liquid-injection molding type equipment is used. Four pair of prototype footwear are fabricated.
