Insole

Abstract

An insole inclusive of a hooked pad has an upper layer and a lower layer which meet and define a closed space for containing a gas flowing therein. The hooked pad is defined and divided into a bottom portion, long end portion, and short end portion. The bottom portion connects with the long end portion and the short end portion, with the bottom portion corresponding in position to a heel, the long end portion corresponding in position to the medial longitudinal arch, and the short end portion corresponding in position to the lateral longitudinal arch. Due to its special structure, the insole provides sufficient support, renders walking or running smooth, gives comfort to the foot, makes lengthy standing less tiring, has a long service life, and incurs low production costs.

Description

FIELD OF THE INVENTION[0001]The present invention relates to insoles and, more particularly, to an insole which provides sufficient support to not only enable a shoe wearer to stand comfortably and walk comfortably, but also provide a buffer for foot treading, thereby enhancing the practicability of the insole.BACKGROUND OF THE INVENTION[0002]A human being's feet bear her or his body weight, regardless of whether s / he is standing, walking, or running. With health awareness on the rise, an insole is often placed in a shoe to protect the human foot therein. In view of this, shoe manufacturers are keen to make insoles lighter, more comfortable, and tougher.[0003]A conventional insole typically comes with an airbag therein to absorb impacts exerted by the heel. However, the airbag is disposed only at the heel-corresponding portion of the insole and thus fails to soothe the human foot completely, because of non-uniform distribution of pressure on the human foot in the course of foot trea...

AI Technical Summary

Benefits of technology

The objective of the patent is to provide an insole with an airbag that can provide support, make walking or running smooth, and provide comfort to the foot while doing so. Additionally, the insole can make lengthy standing less tiring, have a long service life, and incurring low production costs. The insole's special structure achieves these goals.

Problems solved by technology

However, the airbag is disposed only at the heel-corresponding portion of the insole and thus fails to soothe the human foot completely, because of non-uniform distribution of pressure on the human foot in the course of foot treading.

In addition to non-uniform distribution of pressure on the human foot in the course of foot treading, the conventional airbag-equipped insole fails to give sufficient protection to the human foot because of variations in the shoe wearer's posture, center of gravity, and shape of the foot.

When designed to be full-foot sized, the conventional airbag-equipped insole bends to the detriment of its service life while the shoe wearer is walking or running.

Furthermore, the conventional full-foot, airbag-equipped insole has a larger surface area, thereby incurring high production costs.
