ABSTRACT:
An insulated insole construction comprising a layer of plastic mesh material shaped such that when inserted in a shoe, it will have a portion extending over the inner sole of the shoe. A portion of the insole may be bent to form a toe cap to encircle the inner toe area of the shoe and the insole may have an additional portion engaging the inner sides of the shoe in the heel and arch area. The plastic mesh material comprises two spaced mesh-like plastic fabrics separated by a plastic separating material, all of which are encased within plastic films to form a non-collapsible chamber between the plastic films.
