Abstract
A shoe insert includes: a housing insertable in a shoe interior and having perforations formed through the housing for directing moisture-laden air from the shoe interior into the housing, a gas-permeable filter cloth lined on an inside surface of the housing and containing activated carbon in the filter cloth for deodorizing the dirty air, a heating device secured in the housing, a moisture-absorbable dehydrating agent including silica gel filled in the housing for absorbing moisture as laden in the air entering the housing from the shoe interior for dehumidification or dehydration, and a deodorant also filled in the housing for further deodorizing the dirty air entering the housing from the shoe interior, thereby dehumidifying and deodorizing the shoe interior for a comfortable wearing of the shoe; and upon saturation of moisture by the dehydrating agent and odor gas (or vapor) by the deodorant, the heating device is actuated to heat the saturated dehydrating agent and deodorant for regeneration and re-use of the dehydrating agent and deodorant.
