The present invention relates to a shoe having an air circulation function. The shoe has a receiving groove in a central portion of a top surface thereof. The shoe includes a sole having an air chamber, a vent passage, and a passage through which air is discharged toward the receiving groove of the sole, an inner cushion inserted into the receiving groove of the sole to provide a cushioning force for restoring the cushion during walking, an inclined adhesion protrusion disposed along an outer circumference of the receiving groove of the sole, the inclined adhesion protrusion being gradually inclined downward from the outside to the inside, a porous valve plate stacked on a top surface of the inner cushion, the porous valve plate having a lower end circumference surface contacting a top surface of the inclined adhesion protrusion to define a contraction space above the inclined adhesion protrusion, a plurality of valves protruding from a bottom surface of the porous valve plate, the plurality of valves being selectively opened or closed according to the contraction and expansion of the porous valve plate in a state where the valves are inserted into holes defined in the inner cushion to discharge contaminated air within the shoe into the air chamber of the sole, and an intermediate sole and insole which are successively stacked on a top surface of the porous valve plate. The intermediate sole and the porous valve plate may be frequently contracted or expanded through the contraction and restoring space by a load transferred during the walking when compared to shoes according to a related art. Thus, air within the shoes may be physically discharged.
