Problems solved by technology

[0002] Most of the traditionally used insoles are made of one material, which cannot be adjusted to different hardnesses according to the different pressures on the toes, soles and heels when walking, running or jumping, which will not only cause discomfort when wearing , will also cause damage to the feet. This is the problem and shortcoming that currently exists in commonly used insoles and has yet to be overcome.

Abstract

The invention provides an insole compositely molded from multiple materials. Three fourth of the bottom of the insole is made of an EVA (polyethylene foam) material; a heel is made of an elliptoid PUGEL (polyurethane elastomer) material; the inside of a half sole is made of a PORON (shock absorbing pad) foam material; a middle layer and half of the half sole are made of a PU (polyurenthane foam) material; an upper layer is cloth or a sheet attached with a TPU (rubber) film; the PUGEL (polyurethane elastomer) material is made into an ellipse shape; the EVA (polyethylene) foam material is a hardmaterial and can fix positions of bones of a foot to prevent the bones from being distorted and avoid an ankle being sprained; the PORON (shock absorbing pad) foam material inside the half sole can relieve stress of bones of toes; and the elliptoid PUGEL (polyurethane elastomer) material on the heel can buffer in jumping and avoid influencing central nerve due to cervical vertebra injury.

Description

technical field [0001] The invention relates to an insole which is compositely formed by various materials, and mainly relates to the composite molding technology of various materials applied to the insole. Background technique [0002] Most of the traditionally used insoles are made of one material, which cannot be adjusted to different hardnesses according to the different pressures on the toes, soles and heels when walking, running or jumping, which will not only cause discomfort when wearing , also can cause the injury to foot, and this is the problem and the shortcoming that are still to be overcome and solved in the shoe-pad commonly used at present. Contents of the invention [0003] Aiming at the problems and shortcomings in the conventional insole manufacturing technology, the present invention proposes an insole made of multiple materials. [0004] The technical means that the present invention solves the problem and the effect that compared with prior art has i...
