Abstract: Introducing ultraviolet (UV) light to interior portions of footwear alters the environment inside a shoe or other footwear to destroy microorganisms or inhibit their growth. Visible light can also be used to prevent further microorganism growth. Introducing forced air flow through the footwear removes dampness in and thereby deodorizes the footwear. A preferred embodiment comprises an adjustable shoe tree equipped with a UV germicidal light source and electronic safeguards that prevent appreciable leakage of UV radiation outside the shoe.

Abstract: Introducing ultraviolet (UV) light (102, 202) to alter the environment inside a shoe destroys microorganisms or inhibits their growth. Visible light can also be used to prevent further growth. A preferred embodiment comprises an adjustable shoe tree (200) equipped with a UV germicidal light source (202) and electronic safeguards (284, 370) that prevent appreciable leakage of UV radiation outside the shoe.
