Hybrid insole with multi-shock absorbing pad and method for fabricating thereof

Abstract

Provided are a hybrid insole with a multi-shock absorbing pad and a method for fabricating the hybrid insole. The hybrid insole includes an insole body including at least one sheet layer that is formed of an elastic material and has a shape of a human sole; a first absorbing pad means including first to fourth absorbing pad portions attached to the insole body corresponding to a metatarsal region, a tarsal bone region, and a calcaneus region of the human foot, and first to third connecting portions selectively connecting the first to fourth absorbing pad portions; and a second absorbing pad means including a fifth absorbing pad portion attached to the insole body corresponding to the metatarsal region and a phalange region of the human foot.The hybrid insole is configured such that absorbing pads of different structures are disposed to correspond to the bone structure for each region of the foot and the shape of an arch, thus distributing and absorbing the weight load of the human body.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the priority of the Korean Patent Applications NO 10-2020-0097598 filed on Aug. 4, 2020, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.BACKGROUND OF THE DISCLOSUREField of the Disclosure[0002]The present disclosure relates to a functional insole and, more particularly, to a hybrid insole with a multi-shock absorbing pad and a method for fabricating the hybrid insole, in which an absorbing pad corresponding to a bone structure for each region of a human foot is disposed to distribute and absorb the weight load of a human body.Related Art[0003]Generally, an insole may be provided not in a sole of a shoe but in a shoe, a sports shoe, etc., and may function to absorb shock transmitted from the ground while being in direct contact with the entire sole of the foot and to smoothly cope with a change in terrain.[0004]The shoe sole is non-replaceably fixed under an u...

AI Technical Summary

Benefits of technology

The present invention provides a hybrid insole with a multi-shock absorbing pad and a method for fabricating the hybrid insole. The insole has a phalange region that uses a solid absorbing pad, a metatarsal region, a tarsal bone region, and a calcaneus region that use a plurality of absorbing pads having a fluid liquid gel. This invention effectively reduces the weight load applied to the human foot and prevents deformation of the foot.

Problems solved by technology

However, modern people continuously apply shocks to the feet due to weight gain caused by obesity, living on hard concrete floors or asphalt, or poor postures.

The deformation of the dome-shaped arches breaks the balance of the articular cartilages of the body, thus causing a problem in which the weight load is not properly absorbed or distributed.

As such, if the foot does not properly support the weight load of the human body, this causes foot diseases such as plantar fasciitis, and continuously accumulates fatigue in the cartilage of the knee joint, thus causing knee arthritis due to cartilage wear.

However, this is insignificant in the effect of protecting the entire sole.

Furthermore, the above-described invention is problematic in that this does not take into account the fact that the weight load applied to each region of the foot contacting the ground over time when a person is walking or jogging is different, so that this cannot completely prevent the deformation of the dome-shaped arch of the foot.
