ABSTRACT:
A process enabling original primary models to be prepared for fabricating shoes. The process begins with forming a longitudinal profile of a last relative, to a theoretical ground line. The ground line length of said last corresponds to the actual length of the longitudinal profile. Then the profile is divided into three equal parts, thus forming two posterior thirds and one anterior third. A basic longitudinal support is established for the part of the foot which in the two posterior thirds, the support especially affecting the tarsus and metatarsus zone. A basic support is provided for the plantar or flexion part of the foot in the front third. Templates are formed and assemble corresponding to the supports established by the process. Then any voids are filled between the templates in order to form the assembly into a solid basic primary model.
