Résumé : |
Leather is the traditional material for the fabrication of boot and shoe, the reasons being probably (a) its aesthetic value, and (b) the comfort it can impart in wear. The comfort in shoe wear depends on the physical and physicochemical properties of the shoe material and on the physiological and psychological aspects of the wearer. The physiological feeling of comfort depends, as is well known, on the ambient relative humidity and temperature. Hence it is important to determine the temperature and relative humidity over the feet enclosed in shoes and to correlate the resultant values with the feeling of comfort or other wise so as to understand how far the properties of shoe materials influence these values and in order to know which materials impart greater physiological comfort.
Studies have been made to determine the increase in the weight of the shoes due to accumulation of perspiration.”2The properties of shoe materials have been investigated.3—’Attempts have also been made to determine the shoe climate.
Gran8used leather pieces, conditioned to equilibrium, to determine the relative humidity inside shoes. Kennedy2et a!. improved the method of determination of relative humidity using woollen pieces conditioned at O°/ r.h. However, the data for the relative humidity and temperature inside shoes was not available (a) for different hours of wear and (b) when the shoes would become comfortable or uncomfortable in wear. Hence, in the present study, the relative humidity and temperature at several regions of the foot were determined after various periods of wear. In addition, the shoes were made deliberately uncomfortable in wear, by covering the nylon socks, usually worn, by plastic socks which acted as an impermeable barrier. The relative humidity and temperature were determined when the subjects expressed discomfort. Using these values, an attempt is made to arrive at an index, the maximum and minimum values of which might give an idea as to under what conditions of temperature and relative humidity persons might feel comfortable in shoes. |
