ABSTRACT:

FIELD OF THE INVENTION
The present invention relates generally to a shoe insert, and more particularly to the shoe insert that is used inside a woman's shoe to support the surface of the shoe.
BACKGROUND OF THE INVENTION
A shoe insert is usually inserted at the front tip of the shoe to support the inner portion of the shoe, so as to make the shoe's surface straight and upright. Therefore, a shoe insert is a very important part to use inside the shoe, and that manufacturers would like more efforts in improving the shoe insert shapes or materials.
There are various shapes and materials of the shoe insert that can be found on the market. Among those materials are polymeric materials, bubble-wrap material and paperboard material. However, the structure of those materials can be divided into paper material and plastic or bubble plate-shaped. Such structure is defective in design as described hereinafter.
1. The paper ball-shaped shoe insert is taken from a waste paper. Such structure is defective because the support in the shoe is not strong.
2. The plastic plate-shaped shoe insert is rather tough, but it can not be decomposed naturally and that will cause an environmental problem.
3. The bubble plate-shaped shoe insert is light, but it also can not provide durable supports in the shoe and can not overcome the environmental problem.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an improved woman's shoe insert which is free from the shortcomings of the conventional shoe insert described above.
The structure of the present invention comprises an angled surface which is formed at a rear end of the shoe insert from the top and by extending to a seat extending outwardly of the angled surface at a bottom of the insert. The angled surface is approximately centrally located by using a trough locating extending from a top of the seat. The locating trough is broad on the top and narrow on the bottom and is engageable with a front end of a support rod. The rear end of the support rod supports the rear end of the shoe.
Such design of the present invention is cost-effective because it is made from high fiber content recycled waste paper.
The features, functions, and advantages of the present invention will be readily understood upon a thoughtful deliberation of the following detailed description of the embodiments of the present invention with reference to the accompanying drawings.
