Insole with independent supporting of inner and outer foot arches and preparation method thereof

Abstract

The invention provides an insole with independent supporting of inner and outer foot arches and a preparation method thereof. The insole comprises a body (1), wherein an integrated shock-absorbing andcushioning supporting pad (5) is arranged at the heel crown center part and the outer longitudinal arch part of the lower surface of the body (1); a semi-rigid supporting pad (3) is arranged at the inner longitudinal arch part; a calcaneus outwards-rotating limiting module (4) is arranged at one side of the inner longitudinal arch part of the heel part and around the shock-absorbing and cushioning supporting pad (5); a rebounding pad (2) is arranged at the sole part. The insole provided by the invention is combined with the walk gait of a human body and provides corresponding protection settings for the feet to relieve the acting forces of the ground and the human body on the feet according to differences of the acting forces of the ground and the human body on the feet at different periods.

Description

technical field [0001] The invention relates to garment processing, in particular to an insole with independent support for inner and outer arches and a preparation method thereof. Background technique [0002] The main function of the insole is to provide good arch support while providing shock absorption and cushioning for the wearer. [0003] According to the analysis of the gait characteristics of people walking, it is the outside of the heel that first touches the ground during the landing period of the foot. Therefore, under normal circumstances, the wear on the outside of the heel is more severe than that on the inside. When the foot initially touches the ground, under the action of gravity, the ground will form a large impact force against the reaction force of the human foot during this period. If this impact force cannot be well buffered, it will directly act on the ankle. Long-term accumulation is likely to cause ankle joint injuries. [0004] After the outer si...

AI Technical Summary

Problems solved by technology

While providing walking comfort, the insole should be able to combine with the walking gait of the human body, and provide corresponding protection for the foot according to the different force of the ground and the human body on the foot in different periods. Most of the existing insoles on the market cannot Combined with different periods of walking gait, it can reasonably alleviate the different forces on the foot. For example, although most support insoles can provide overall support for the foot, they cannot solve the problems of the heel and heel core in the early stage of landing. The problem of cushioning and shock absorption on the outside of the heel; although most cushioning insoles can provide cushioning and shock absorption for the foot, they cannot provide effective foot support; at the same time, most of the existing insoles on the market cannot effectively limit the ground The torsional force of the heel rotating from the outside to the inside in the later period cannot provide sufficient anti-thrust during the propulsion period, thereby reducing the safety of walking and the comfort of wearing
