A ventilation sole for shoes is disclosed. The ventilation sole of the present invention has a vent hole (110), which is formed in a sidewall of the sole, an air supply hole, which is formed in the upper surface of the sole (100), and an air passage, which communicates the air supply hole with the vent hole, such that outside air is supplied into the shoe. Furthermore, the present invention is characterized in that a vent hole control device (200), which is opened or closed by a knocking operation, is installed in the vent hole (110) such that part thereof protrudes outside the sole (100), thus making it possible for a user to selectively open or close the vent hole (110), as necessary.
A ventilating sole for a shoe, including a vent hole formed in a sidewall of the sole of the shoe, at least one air supply hole formed in an upper surface of the sole of the shoe, and an air passage, through which the air supply hole communicates with the vent hole, such that an outside air is supplied into the shoe,

The present invention relates, in general, to ventilation soles for shoes and, more particularly, to a ventilation sole for a shoe which makes it possible for a user to control the opened or closed state of a vent hole, which is formed in the sole of the shoe to supply outside air into the shoe.
In the case of typical shoes, because they are made of leather or synthetic resin, which is poorly ventilated, when a user wears the shoes for a long time, the space inside the shoes is heated and the shoes absorb moisture resulting from sweat of the user. Thereby, mold accumulates in the shoes, thus raising problems of foot odors and athlete's foot.
To solve the above-mentioned problems, ventilation soles for shoes which can ventilate the space inside the shoes were proposed.
