||Thermal effects of steel toe caps in footgear
||Mar. 1999, Vol.23, No.5-6, p.431-438. Illus. 11 ref.
||The possible thermal effects of steel toe caps in footwear were investigated. Two models of boots were used, each manufactured in two variants - with and without steel toe caps. Boot insulation was measured with an artificial, heated foot (AHF). Cold exposure consisted of sitting for 60min at -10°C. There were no differences between insulation levels of boots with and without steel cap for one boot model, but the differences were statistically significant for the second model, showing slightly higher insulation values for the boot without steel cap. Significant differences were found for both models regarding the rate of change of heat loss from AHF when its location was changed from warm to cold and back to warm. The rise and decrease of heat loss from AHF depended on the rate of temperature change of the boots. The results showed that a faster change in heat loss from AHF occurred for boots without steel toe caps. The effect may be attributed to the higher mass and heat contents of the boots with steel toe cap.
