Foot shape determination data generation method, shoemaking method, finished shoe search method, customized shoe manufacturing support system, and finished shoe search system

A foot shape determination data generation method includes: acquiring foot shape 3D data (FS3D) by measuring a three-dimensional shape of a barefoot (BF) of a subject (P); generating a virtual midsole (VIS) for measurement on the basis of the acquired foot shape 3D data (FS3D); generating corrected foot shape 3D data (CFSD) by adding data of the virtual midsole (VIS) to a sole portion of the acquired foot shape 3D data; and acquiring foot shape determination data (FSSD) by measuring a predetermined size of the corrected foot shape 3D data (CFSD) in order to determine the shape of the foot. 脚形状确定数据生成方法具备：通过测量被测量者(P)的赤脚(BF)的立体形状，从而取得脚形状3D数据(FS3D)；基于取得的所述脚形状3D数据(FS3D)生成测量用的虚拟中底(VIS)；通过对取得的所述脚形状3D数据的脚底部分附加所述虚拟中底(VIS)的数据，从而生成校正脚形状3D数据(CFSD)；以及为了确定脚的形状而测量所述校正脚形状3D数据(CFSD)的预先规定的尺寸，从而取得脚形状确定数据(FSSD)。
