ARTICLE ANNOTATION

quote
Since each type of footwear is designed for operation at certain intervals of meteorological conditions indicators, the article analyzes the influence of foot temperature topography on the justified choice of footwear design and materials for operation in the winter period of footwear wear. Human heat perception depends to a greater extent on the temperature of the foot. The analysis of the temperature topography of the foot has shown that, despite the relatively small size of the foot, its temperature field is heterogeneous, that the lowest temperature of the foot is observed on the toes, and the range of foot temperature fluctuations is 6-8°C. The results of studies confirm that the maximum permissible critical foot temperature should be 27-29°C. At this temperature, the approximate temperatures of the skin of the big toe were 18-20°C, the midsole 21-22°C and the back of the foot 28-30°C. Each type of footwear is designed to operate at certain intervals of indicators of meteorological conditions and have certain heat-protective properties. This principle is the basis for calculating the assortment of footwear for the cold period of wear. When developing new models of military boots used in snow-covered mountainous areas of Uzbekistan, the II cold period of footwear wear with the temperature interval of minus 20.0°C ÷ 34.9°C and the required total thermal resistance of sets of materials not less than 0.24 m2·°C/W is justified.
