PROBLEM TO BE SOLVED: To produce a last by a method wherein an arbitrary pressure is applied on a part produced being smaller than the actual dimension of a foot to from a clamp part while a shoes-shaped foot part cubic contour body is softened more than several second under the conditions of the surface temperature below a fixed value at a melting point below a fixed value and under such a condition, the foot part cubic contour part is hardened to correct it into a proper shape. ;SOLUTION: A thermoplastic resin which is kept soft more than 5 second at the surface temperature of below 50°C with a melting point of below 100°C while being hardened at a room temperature is softened and it is extended along the contour of a toe, a heel, a sole and internal and external sides to from a foot part cubic contour body (steps 1 and 2). While the foot part cubic contour body is softened, an arbitrary pressure is applied on a part made smaller than the actual dimensions of the foot to form a clamp part while under such a condition, it is hardened to correct the foot part cubic contour body (step 3). A last is produced based on the foot part cubic contour body corrected (step 4). Thus, a proper footprint can be taken.;COPYRIGHT: (C)1997,JPO
