Definitions

  • a mold and cooperating form which define, by means of projections, regions from which the injected plastic material will be excluded. Such regions may, for example, define where the cuts are to be made to form the tongue.
  • a flexible sheet of material 20 is positioned between socks l3 and 14 in the region de fined by the projections 18.
  • Sheet 20 will be selected so as to be comprised of a material to which the foam will not adhere.
  • sheet 20 will typically be comprised of polyvinyl chloride. Even if the mold and form meet perfectly, there is a residual possibility that a small amount of the foam will penetrate into the region between socks Band 14 within the area defined by projections 18.
  • the layer 20 insures that the socks 13 and 14 will not be joined together by the foam in these regions and thus insures that there will be a void for the purposes to be described below.
  • the purchaser will put on socks, such as the socks of FIG. 7, and fit them into the boots. Thereafter, the wearers malleoli are provided with protection by injecting foam material through tip 19; the material injected at this time spreading into the cavity formed between socks 13 and 14 by means of mold projections 18 and sheet 20 during the initial molding step.
