Abstract: A shoe pad or insole with areas of adjustable thickness for fitting various shapes of feet in a shoe, boot or the like. The insole comprises superimposed pad layers made of a flexible material, such as leather, for the top layer and cork for the remaining pad layers. A pressure adhesive, such as hot-melt glue, is used to releasably interconnect the superimposed pad layers, so as to allow repeated peel-off removal and reconnection thereof, for specific adjustment of the thickness of various insole areas of the insole for best fit of the foot inside the shoe. This includes discrete thickness adjustment of the arch-support portion of the insole and of the front and rear portions thereof.
