Description

The present invention relates to a shoe, and more particularly to a shoe in which the inside of the shoe does not get stuffy.

If you continue to wear leather shoes, boots, boots, etc. for a long time, the moisture generated from your feet will fill the inside of the shoes, causing not only a bad odor due to stuffiness, but also the foot's skin will be soaked and athlete's foot will develop between your toes. Easier to do.

Therefore, it has been attempted to provide a ventilation hole on the shoe sole or the upper surface to eliminate stuffiness in the shoe (Patent Document 1).

In addition, an air bag is built into the rear part of the shoe heel, and the air is taken in through the check valve from the outside air intake on the side of the rear part of the shoe heel by suction as the air bag contracts and swells. A structure has been proposed in which the air in the air bag is released into the shoe by contraction from the inside so as to eliminate stuffiness in the shoe (Patent Document 2).
