PROBLEM TO BE SOLVED: To solve the problem that when shoes are worn for a long time, feet get sweaty and get athlete's foot.SOLUTION: There are many people who are troubled by sweaty feet caused by humidity in shoes as there is no vent port from which humid air can exit. To solve this problem so as for humid air to go out, the top and bottom of a flexible material serving as a pipe-shaped air vent and is not crushed when being pressed a little is covered with air-permeable material, which is an air flow and attached from the top of right and left feet to the ankles for preventing humidity in shoes. The more the wearer walks, the more the point between toes and the top of the feet serves as a pump. Thus, humid air goes out and new air goes in, so the feet do not get sweaty and athlete's foot and rash are prevented, and the wear can walk comfortably without minding feet. |
