  • the second compressibility is approximately 10-40% greater than the first compressibility, with at least 10% greater or at least 20% greater than the first compressibility being preferred. So constructed, if portions of the insert having the second compressibility are exposed along the sides of the article of footwear, a customer, pressing the exposed portions will readily appreciate the insert's cushioning effect.
  • the internal compressible element may comprise a single unitary member having either a plurality of holes, ridges or none at all to best suit the effect on the foot of the user and to minimize weight where necessary.
  • the internal compressible element may comprise a plurality of circular/oval/ formations/patterns positioned along the outer edges. Each of the plurality of formations/patterns may still further be enhanced with color for visual impact.
  • the insert may comprise a variety of shapes to optimally flex with the bend lines of the foot. As shown in the drawings however, one insert is preferably of trapezoidal shape and a second insert is preferably of kidney-like shape.
  • the material for the casing may be selected from the following exemplary materials bearing in mind that other suitable materials are also contemplated: thermoplastic polyurethane (TPU), polyester-TPU, polyether-TPU, polyester-polyether TPU, polyvinylchloride, polyester, thermo plastic ethyl vinyl acetate, styrene butadiene styrene, TPU blends including natural and synthetic rubbers.

  • standard blow molding equipment may be used in which a tube of resin is dropped from a die and mandrel. The compressible element or foam is placed on one end of a pin. The other end of the pin is inserted into the blow nozzle of the blow molding equipment. A tube of parasin is dropped over the foam/pin. Mold plates close around foam and parasin. Air is blown up and around foam and pin, pushing the parsin into the cavities of the mold. Component is pulled from the mold. Pin is removed. Components are die cut from flashing. Blow holes in blow molded plastic are high frequency welded shut.
  • the casing is created with two pieces.
  • the first piece is vacuum formed into a shell.
  • the foam is placed in the shell (centered on locator pins to ensure there is an air gap, e.g., a 1-3 mm air gap).
  • a second piece of casing (un-molded film) is placed on top of the first piece and is welded to the first piece of molded casing using a high frequency weld. Two vacuum formed pieces can also be welded together with the insert inside.
  • an extruded tube is formed.
  • the insert is placed inside the tube and the edges of the tube are high frequency welded.
  • the casing is created with two pieces.
  • the first piece is injection molded into a shell.
  • the foam is placed in the shell (centered on locator pins to ensure there's a 1-3 mm air gap).
  • a second piece of casing (un-molded film) is placed on top of the first piece and is welded to the first piece of molded casing using a high frequency weld.
  • Two injection molded pieces can also be welded together with the insert inside.
  • the insert is formed so that it is smaller than the casing (creating a gap, e.g., 1-3 mm air gap).
