<p>PROBLEM TO BE SOLVED: To remove humidness around a foot due to bad ventilation inside a boot to cause a sanitary trouble such as bad smell and accelerate propagation of miscellaneous germs. SOLUTION: Ventilation holes 4 are formed between an outer layer 2 and an inner layer 3 in this boot 1 to be opened in an upper part 5 of the boot 1 and extended to a lower part 6. A lower part of the ventilation hole 4 is formed through an opening part 14 in the inner layer 3 to be communicated with the inside 7 of the boot 1. By means of the ventilation hole 4, outer air is introduced when temperature inside the boot is higher than that of outer air, and inner air is discharged when temperature of inside of the boot 1 is lower than that of outer air, so air is circulated. Air inside the boot 1 is thus effectively circulated with outer air by temperature difference between the inside and the outside of the boot 1, thereby favorable feel to wear can be constantly achieved.</p> |
