ABSTRACT:
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.
