Ventilating shoe pad

Abstract

A ventilating shoe pad includes a pad body made of plenty of elastic fiber that is loosely and separately interwound together, with numerous gaps formed among the interwound fiber. The pad body is formed by thermal compression with a protective edge slightly extending upward obliquely at the peripheral edge corresponding to the recessed portion and the heel of a user's foot. The ventilating shoe pad of this invention has good permeability and good elasticity, safe and comfortable in using.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates to a ventilating shoe pad, particularly to one having good elastic buffering effect and good permeability. [0003] 2. Description of the Prior Art [0004] Formerly, shoes, such straw sandals and clogs, are simple in structure, but their insoles that contact with a user's feet are comparatively hard without good elasticity. Later, shoe pads have been designed and used for improving the above-mentioned drawback. A conventional shoe pad, as shown in FIG. 1, is made of foam plastic or leather or synthetic leather to be fitted on the insole of a shoe for thickening the sole of the shoe or reinforcing treading elasticity so as to prevent a user's feet from being hurt.

AI Technical Summary

Benefits of technology

[0006] The objective of the invention is to offer a ventilating shoe pad including a pad body made of plenty of elastic fiber that is loosely and separately interwound together, with numerous gaps formed among the interwound silk. The pad body is thermal-compression formed with a protective edge slightly extending upward obliquely at the peripheral edge corresponding to the recessed portion and the heel of a foot. The ventilating shoe pad of the present invention has good elastic buffering effect and good permeability, safe and comfortable in using and able to keep feet dry to avoid causing skin diseases.

Problems solved by technology

Formerly, shoes, such straw sandals and clogs, are simple in structure, but their insoles that contact with a user's feet are comparatively hard without good elasticity.

However, most of the conventional shoe pads can hardly have both good permeability and elastic buffering effect.

For instance, a shoe pad 1 shown in FIG. 1 made of foam plastic has good elasticity but lacks good permeability, while a shoe pad made of leather or synthetic leather with a close structure has not good elasticity and is worse than the foam-plastic shoe pad 1 in permeability.

Such shoe pads with poor permeability cannot produce air convection between the sole of a user's feet and the insole; therefore, it is likely to produce stinking smell inside the shoe and make the user sweat on the sole of the foot to wet the interior of the shoes and gather mold therein, liable to cause skin diseases on a user's feet.
