  • Publication number: 20070261273
    Abstract: A shoe having photoreactive components, such as a sole, a heel, and/or a series of straps. Each photoreactive component is made from a mixture of a base material, such as rubber, plastic, or polymer, and a photoreactive composition, such as a spiropyran compound or a spirooxazine compound. When exposed to ultraviolet light, the photoreactive components of the shoe reversibly change color.
