Abstract
Operational characteristics of currently created materials and products of aviation equipment. Such conditions, especially in the winter period, largely correspond to the quality of clothes and shoes. The paper presents the results of experimental studies of the thermal conductivity of different types of insoles for shoes. Physical and mathematical models of heat transfer are proposed when a person moves from a warm room to the street. The thermal insulation ability of three types of insoles for shoes was studied and time is shown.
