Abstract:
1. A shoe comprising: an upper part having a through hole formed adjacent to a front part of the upper part; a shoe sole mounted to a lower portion of the upper part, the shoe sole including an air channel at a front part of the shoe sole and an air passage extending from the air channel to a rear part of the shoe sole in fluid communication with the air channel; an elastic unit formed at a lower area of the shoe sole, at least a portion of the elastic unit defining an inner cavity corresponding to the air passage of the shoe sole, the elastic unit being deformable while reducing its inner cavity when a user wearing the shoe steps on the ground and being restorable while restoring its inner cavity when the user releases the shoe from the ground, the elastic unit having an elastic groove formed upward on a lower surface of the shoe sole along each lateral side of the elastic unit for facilitating said deformation and restoration of the elastic unit; and an air circulation unit disposed at a front part of the shoe sole, the air circulation unit defining an air inlet for passing air there-through, the air inlet being in fluid communication with the through hole of the upper part for ventilating inside of the shoe, the air circulation unit including an air circulation path extending through the air circulation unit, the air circulation path being in fluid communication with the air passage of the shoe sole via the air channel of the shoe sole such that, when the shoe is released from the ground, air is introduced from outside to the restored inner cavity of the elastic unit and air passage via the air circulation unit and also to an interior of the upper part through the through hole of the upper part due to said restoration of the inner cavity of the elastic unit inducing the air introduction for the ventilation of the shoe.
