Abstract: In the shoe drying apparatus according to the present invention, the ozone-containing air or the mixed air generated and heated by the sanitizing assembly is taken in through intake duct and moves through the main conduit and the auxiliary conduit into the shoe-holding member to sanitize inside of a shoe. After sanitizing, the mixed air moves from inside of the shoe to the interior of the housing, and comes back through return air duct to the anion generator where it is purified and deodorized. The purified air is subsequently sent to a motorized fan contained within the sanitizing assembly. During such circulation, shoes can be sanitized. Moreover, an ultraviolet lamp is installed on the shoe-holding member to sanitize inside of the shoe.
