Abstract
Abstract The present invention relates to a footwear insole with an integral sock lining embedded therein; and to a method of making a sample comprising: preparing a board of a material selected from the group of porous and foamed cross-linked synthetic polymers; preheating the board to at least the softening point of said material; pressing the board and stamping into it a footprint shaped cavity while cooling by a stamping device having a stamping die and a stamping die bearing pressing plate; attaching a sock lining to said footprint shaped cavity; and suitably cutting the board. The sock lining may be fastened to the stamping die bearing pressing plate. Alternatively, said plate may carry an integral stamping die and the sock lining inserted after storing.
