  • Patent number: 4192086
    Abstract: A laminar insole for footwear has a top, porous, non-woven, non-absorbent layer or mat of plastics material fibers, an intermediate moisture absorbing paper or other non-woven layer impregnated with deodorizing material, such as activated charcoal, coated on the paper fibers, and a bottom open-cell plastics foam cushion layer cured in-situ on the intermediate paper layer. The top and intermediate layers are stitch bonded together by pushing fibers from the top layer into and through the intermediate layer which also form anchors for the bottom layer. No added adhesives are needed to unite the layers. A myriad of holes are punched through all of the layers exposing the deodorizing chemical in the paper layer to air that is pumped through the insole as the foam layer is compressed and expanded upon application and release of foot load on the insole as in walking.
