LIGHTWEIGHT INSULATED FOOTWEAR
Abstract
A number of candidate materials were compounded, tested, and evaluated with an aim toward the development of a lightweight (15 oz. per boot), impermeable, (water absorption maximum weight 5%), insulated, (for service down to -20 deg.) boot for periods of up to 2 hours of inactivity. These materials included expanded elastomers and plastics, solid plastics, metals, fabrics, adhesives, and coating materials. Design and fabrication studies were conducted to incorporate the most promising materials into a prototype boot, and to determine the insulating properties of the materials used singly and in combination with each other. Based on the data obtained, prototype boots were assembled. An experimental pull-on type boot weighing 15 1/2 ounces was worn by the Project Officer in the Climatic Test Chambers at the U. S. Natick Laboratories at -30F. for a period of 2 hours. These studies indicate the feasibility of producing lightweight insulated boots through materials research.
