The method of stiffening a selected area of a shoe component of flexible sheet material in which a layer of molten synthetic polymeric material is coated on the area to be stiffened, rigid, preferably heat-softenable, granules are applied to the coating layer while the coating material is soft to cause the granules to adhere, and the shoe component is pressed against a second flexible shoe component with the coating and granules between the parts and with the coating in heat softened condition to force the coating material through openings between the granules and into wetting engagement with the second shoe component. The assembled shoe components may then be shaped and the polymeric material cooled to form a layer of hardened polymeric material with the granules locked in it as reinforcing stiffening bodies.
