There is. The inside of the shoe is ventilated by exhausting the moisture inside the shoe to the outside of the shoe or inhaling the air outside the shoe into the inside of the shoe through the vent holes of the outer sole and the inner sole. Specifically, when the moisture inside the shoe is exhausted through the ventilation hole, the air outside the shoe enters through the opening on the upper side of the shoe. Conversely, when the air outside the shoe is sucked in through the ventilation hole, the opening on the upper side of the shoe is Moisture will come out from the part inside the shoe.

Further, as a second conventional technique, an air pump is disposed on the heel portion of the outer sole which is the ground side of at least a two-layered shoe sole, and the air pump is provided on the upper surface side of the outer sole. There is a configuration in which a ventilation groove is provided that communicates from the shoe to the toe portion, and further a ventilation hole is formed in the insole on the foot contact side of the shoe sole.
