Study on Characteristic of Temperature and Humidity in Sport Shoes

The purpose of this study is to find the comfort of sports shoes by measuring the temperature and relative humidity of three parts of sports footwear through the jogging process for 25 athletes using real-time measurement system.After running each subject answered the subjective comfort questionnaire.Results:with the running time,the curves of temperature on three parts inside shoes increase and the curves of relative humidity on three parts inside shoes dropped.The faster athlete run,the higher was the temperature of front foot.The temperature of arch and the humidity of three parts of foot increased rapidly after running.By measurement and comparison of temperature variation and relative humidity variation in the forefoot,arch and heel inside shoes,we can know the air flow characteristic by temperature of sport shoes,and the vapor permeability characteristic by humidity of sport shoes.The lower temperature and humidity in good sport shoes can provide comfort for athlete during running.
