Summary, in English

The study aimed to find out the influence of sweating on footwear insulation with a thermal foot model. Simultaneously, the influence of applied weight (35 kg), sock and steel toe cap were studied. Water to 3 sweat glands was supplied with a pump at the rate of 10 g/h in total. Four models of boots with steel toe caps were tested. The same models were manufactured also without steel toe. Sweating reduced footwear insulation 19-25 % (30-37 % in toes). During static conditions, only minimal amount of sweat evaporated from boots. Weight affected sole insulation: reduction depended on compressibility of sole material. The influence of steel toe varied with insulation. The method of thermal foot model appears to be a practical tool for footwear evaluation.
