Manufacturing method of insole and insole manufactured by the method

Abstract

A new manufacturing method produces an insole that fits a user's foot properly and that is manufactured in a shorter time at a lower cost. The manufacturing method includes steps of: acquiring information on a user's foot by a foot printer; selecting a basic part 2 based on the acquired information; attaching various modification parts 3 to the selected basic part 2 arranged in a trial shoe 1; determining whether the trial insole including a combination of the basic part 2 and modification parts 3 is properly fitted to the user's foot in walking and standing statuses; repeating the steps from selecting to determining until the most fitting combination of the basic part and modification parts is determined; reproducing the determined trial insole in a three-dimensional CAD based on the most fitting combination; and manufacturing an insole by cutting out material based on the reproduced trial insole in the three-dimensional CAD.

What is claimed is: 
     
         1 . A manufacturing method of an insole comprising steps of:
 acquiring information on a user's foot by a foot printer, wherein the information comprising a pressure pattern of a sole and contour of the foot;   selecting a basic part among a group of basic parts based on the acquired information;   attaching various modification parts to the selected basic part so as to form a trial insole;   determining whether the trial insole comprising a combination of the basic part and modification parts is properly fitted to the user's foot or not in a walking and in a standing status;   repeating steps from the selecting step to the determining step until the most fitting combination of the basic part and modification parts is determined;   writing the determined most fitting combination in the foot print;   reproducing the determined trial insole in a three dimensional CAD based on the most fitting combination; and   manufacturing an insole by cutting out a material based on the reproduced trial insole in the three dimensional CAD.   
     
     
         2 . The insole manufactured by the method described in  claim 1 .
