  • Method for forming soles
    Patent number: 5879605
    Abstract: The invention provides a method for preforming soles which includes compressing a foot so as to push soft fat tissue masses of the foot on its underside and inner and outer lateral arches inward toward a top of the leg; making an accurate molding of the foot thus compressed by using material for making the molding which is capable of flowing into cavities which result from the compression of the foot and which is capable of filling the cavities; removing the foot from the molding; and placing a sole blank on a bottom of the molding, the blank preferably having been treated so as to be capable of being shaped by pressure from a foot on it; and pressing the foot, which is still compressed, onto the blank so as to shape it between an inner face of the foot and the bottom of the molding.

  • Removable insoles
    Patent number: 4580356
    Abstract: The removable insole for shoes consists of a thin strip (1) of plastic foam, such as polyolefin foam, in the general shape of the foot.This strip (1) has grooves (6, 7, 8) which are located at the edge of the insole or delimiting zones (3, 4, 5) on the insole which are of different thicknesses, and thus of different densities. The edge of the insole is bevelled (9, 10).The insole (1) gradually becomes permanently deformed on contact with the foot and finally adopts the profile thereof. The grooves (6, 7, 8) allow the insole to change shape more easily.
