Abstract

A method of manufacturing a shoe insole includes 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 comprising:

providing an upper cover sheet conforming in shape to an inner bottom of a shoe, providing a lower cover sheet conforming in shape to the inner bottom of the shoe, and providing an insole body, wherein the shoe insole comprises the insole body being retained between the upper cover sheet and the lower cover sheet, the method further comprising;

taking a padded foot sole form in a first form member by applying test pads to selected regions of a sole of a bare foot of a user which uses the shoe insole and applying the bare foot of the user with the test pads applied thereto to the first form member to thereby obtain test pad marks in the padded foot sole form;

obtaining insole pads having same respective shapes as respective shapes of the test pads, the insole pads being distinct from the test pads, applying the insole pads to an upper surface of an insole frame having a shape with a surface contour that matches the bare foot of the user using the test pad marks of the padded foot sole form as a guide to place the insole pads respectively in the same locations as corresponding ones of the test pad marks,

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 bare foot sole form in a second form member 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 bare foot sole form.

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

wherein the first and second form members each comprise a respective foot sole form sponge, and each of the bare foot sole form and the padded foot sole form is taken by causing the user to push the respective foot sole form sponge with the sole of the foot and move over and out of the respective foot sole form sponge in a walking motion.

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

wherein the insole frame is manufactured to exclude a toe region,

the method further comprising:

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

wherein the insole body further includes 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.

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

wherein the shoe insole includes the upper cover sheet, the lower cover sheet, the insole frame, and the insole pads, the insole frame and the insole pads being disposed between the upper cover sheet and the lower cover sheet, and

wherein, in a transverse cross-sectional view of the shoe insole, an outer peripheral surface of the insole frame is located inward of the upper cover sheet and the lower cover sheet.
