Abstract
A process for manufacturing insoles from flexible, porous and stickable sheet plastic material by sheering the sheet to form a peripheral cut of the insole and an internal cut in the heel area to form an open area surrounded by a land area. The insole is then placed in a mold die and plastic is injected to fill in the open area and surround the land area to conform to a predetermined contour. The insole is stabilized in the die by a plurality of rods positioned within the die.
