Benefits of technology

[0005] It is another object of the present invention to provide a shoe having soles and / or straps that are photoreactive themselves, without a need to apply additional designs or materials to achieve a photoreactive effect.

Problems solved by technology

However, these previous attempts essentially consist of attaching photoreactive designs to existing shoes.
There is not, however, a shoe that has components, such as soles and / or straps, that are photoreactive themselves, instead of having photoreactive designs applied thereto.

Embodiment Construction

[0012] The present invention is directed to an article of footwear, which may be any type of shoe, sneaker, sandal, boot, or other article worn on a foot. By way of example, FIG. 1 shows a men's sneaker 1 in accordance with the present invention, and FIG. 3 shows a women's casual shoe 101 in accordance with the present invention.

[0013] As shown in FIG. 1, a sneaker 1 may be composed of a sole 10, an upper portion 20, laces 30, and one or more optional straps 40. Sole 10 may be made of a base material such as plastic, rubber, polymer, or any other suitable material, which has been mixed with a photoreactive composition as discussed below. Upper portion 20 may be attached to sole 10 to complete the sneaker's shape, as shown, and may be made of leather, canvas, or any other suitable sneaker material. Laces 30 may be threaded through a series of eyelets 35 so that they may be tied to secure sneaker 1 on a wearer's foot.

[0014] Optional strap 40 may be attached to sneaker 1 over or abov...

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.

Description

BACKGROUND OF THE INVENTION [0001] This invention relates to shoes having photoreactive components. More particularly, this invention relates to shoe soles and straps which have photoreactive compositions mixed into the components themselves, so that the components change color when exposed to ultraviolet light. [0002] There have been previous attempts at creating shoes having designs which change from colorless to a particular color, or from one color to another, upon exposure to ultraviolet light. However, these previous attempts essentially consist of attaching photoreactive designs to existing shoes. For example, one such shoe utilizes screen-printing to apply a photoreactive design. Another relies upon the application of a separate photoreactive panel by stitching or an adhesive. There is not, however, a shoe that has components, such as soles and / or straps, that are photoreactive themselves, instead of having photoreactive designs applied thereto. [0003] It therefore would be ...
