The aim of study was to examine the effect of ventilation shoe which was made to improve thermal comfort of the foot. The ventilation shoe had the function to send off the air of the tip outside and to send the air of outside into the tip of a toe. The effect of the ventilation shoe was verified by the ventilation experiment by the tracer gas method. Moreover, it was verified by measuring the viable cell count after it had been put on continuously one week by subjective experiment. By water vapor transmission experiment of shoe in which a synthetic leather shoe was comparison with mesh type shoe, it was found that moisture transmission hardly occur for the synthetic leather shoe comparison with the mesh type shoe. By tracer gas method, the ventilation rate of ventilation shoe was compared with the dummy shoe and the mesh type shoe. It was clarified that the ventilation rate of ventilation shoe was about 40 percent improved comparison with the dummy shoe while the mesh type shoe was 60 percent improved with the ventilation shoe. By measuring the viable cell count after week by subjective experiment, it was clarified that in the dummy shoe remarkably a lot of viable cell counts become insanitary easily from other parts. It was suppressed at the level that the bacterium in the tiptoe is the same as other parts in the ventilation shoe. It was suggested that the enforced ventilation by paving be effective while ventilating it to maintain hygiene from the above-mentioned result.
