ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to a shoe insert, and more particularly to an insert that is used inside a shoe to support the surface of the shoe in a straight and upright manner.
BACKGROUND OF THE INVENTION
A shoe insert is usually inserted so as to reside at the front tip of the shoe to support upwardly inner portion of the shoe. This causes the shoe's surface to be straight and upright. The shoe insert is which is a very important part to use inside the shoe. This will cause manufacturers to give more efforts in improving the shoe lining whether on the shapes or on the materials.
Nowadays, various shapes and materials of the shoe lining can be found on the market. Among those materials are plastics, bubbles, and papers. However, the structure of them can be divided into a paper ball-shape and a plastic or bubble plate-shape. Such structure is defective in design as described hereinafter.
1. The paper ball-shape of the shoe lining is taken from a waste paper. This structure does not adequately support the shoe material in an upright manner.
2. The plastic plate-shape of the shoe lining is tough and not biodegradable, but it can not be decomposed naturally and that will cause an environmental problem.
3. The bubble plate-shape of the shoe lining is light, but it also cannot adequately support the material of the shoe and does not remove the environmental problem.
SUMMARY OF THE INVENTION
The primary objective of the present invention to provide a shoe insert which is free from the shortcomings of the conventional shoe insert described above.
The structure of the present invention shoe insert is of a hollow construction at the bottom. This will correspond to the area on the inner sole of the shoe. The shoe insert is formed with a seat which is provided with a through hole on a top surface thereof. Such design of the present invention is cost-effective because it is made from high fiber content recycled 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.
