Abstract

A method of manufacturing a shoe insole, comprising including an upper cover layer and a lower cover layer conforming in shape to the inner bottom of the shoe, and an insole body retained between the upper cover layer and the lower cover layer, taking a foot sole form to which pads are applied to selected regions of a sole; taking a foot sole form; manufacturing an insole frame having a shape conforming to a three-dimensional shape of the foot sole form; and applying insole pads to an upper surface of the insole frame, based on positions of marks of the test pads of the foot sole form to which the pads are applied, wherein the insole body includes the insole frame to which the insole pads are applied.

Claims

1. A method of manufacturing a shoe insole including an upper cover layer conforming in shape to an inner bottom of a shoe, a lower cover layer conforming in shape to the inner bottom of the shoe, and an insole body retained between the upper cover layer and the lower cover layer, the method comprising:

taking a foot sole form to which pads are applied, the foot sole form being a foot sole form to which test pads are applied to selected regions of a sole of a bare foot of a user which uses the shoe insole;

applying insole pads having the same shapes as shapes of the test pads, to an upper surface of the insole frame having a shape conforming to the bare foot of the user, based on positions of marks of the test pads of the foot sole form to which the pads are applied,

wherein the insole body includes the insole frame to which the insole pads are applied.

2. The method of manufacturing the shoe insole according to claim 1,

the method further comprising:

taking a foot sole form of the bare foot of the user; and

manufacturing the insole frame such that the insole frame has a shape conforming to a three-dimensional shape of the foot sole form of the bare foot.

3. The method of manufacturing the shoe insole according to claim 1,

wherein each of the foot sole form of the bare foot and the foot sole form to which the pads are applied is taken by causing the user to push a foot sole form sponge with the sole of the foot and move over out of the foot sole form sponge.

4. The method of manufacturing the shoe insole according to claim 1,

wherein the insole frame is manufactured to have a shape in which a specified region being close to tiptoes and including a region corresponding to toes is missing,

the method further comprising:

providing a buffering layer on the upper surface of the insole frame to which the insole pads are applied, the buffering layer conforming in shape to the inner bottom of the shoe,

wherein the insole body includes the insole frame to which the insole pads are applied, and the buffering layer.

5. The method of manufacturing the shoe insole according to claim 1,

wherein the test pads applied to the sole of the bare foot of the user are selected from a test pad set including a plurality of test pads which are different from each other in shape and correspond to a plurality of specified regions of the sole of the foot to which the test pads are applied, respectively, and

wherein the insole pads applied to the upper surface of the insole frame are selected from an insole pad set including a plurality of insole pads having the same shapes as shapes of the plurality of test pads included in the test pad set, respectively.
