In 1988, the U.S. Army began a program to develop a new combat boot for dismounted soldiers and marines operating in cold and wet environments where the mean monthly temperature ranges between - 10 deg and 20 deg C. The new Intermediate Cold Wet Boot ICWB was designed to fill the protective void between the uninsulated U.S. Army Standard Combat Boot and the highly-insulated U.S. Army Extreme Cold Weather Vapor Barrier Boot. The development of the ICWB has been managed under a unique U.S. Army Pre-planned Product Improvement Psup 3I program that is designed to continuously improve the protective performance of the boot through the rapid integration of proven technological advances in design, fabrication, and materials. Since 1991, numerous changes have been made to the ICWB under this dynamic Psup 3I process. These include improvements to the boots outer leather, insulation, waterproofbreathable membrane, insole, and midsole as well as other enhancements to the structure of the basic boot. Since the boots inception, the Biophysics and Biomedical Modeling Division of the U.S. Army Research Institute of Environmental Medicine has been responsible for extensive biophysical and physiological evaluations of current and prototype versions assessing the potential impact of new technologies on the environmental protective capabilities of the ICWB. The continuous adaptation of improved features to the ICWB has resulted in a boot with a high degree of wearer acceptance within the U.S. military and could serve as a model for future protective clothing procurement by other NATO countries.
