Lightweight Insulated Footwear for Cold-Wet Conditions
Abstract
Four hundred and fifty pairs of lightweight, insulated polyurethane footwear are fabricated. Construction is based on a design developed under recently completed contracts and optimized during the present work. It is demonstrated that they can be produced in a repetitive manner utilizing skills and techniques not unlike factory operations except on a reduced scale. The outerskin is applied by an electro-coating system which permits a fine control of spray deposition. Significant improvements in closure, surface bloom, adhesion of outer- skin and larger socklinings for easer fitting are noted. A ski shelf and groove in heel design is developed, but not applied to the product at this time.
