    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • The base or base layer of the embodiment in the invention can be made by thermoplastic material such as Ethylene Vinyl Acetate (EVA), Polyvinyl Chloride (PVC), or Polyethylene (PE).
  • Referring to FIG. 1, the method for making an insole of the present invention comprises a step (1): preparing a base 10 and attaching at least two reinforcement layers 20 on a top of the base 10, a top layer 30 attached on the base 10 and covering the at least two reinforcement layers 20, respective peripheries of the top layer 30 attached to the base 10 so as to form a combination unit, and
  • a step (2): pressing and cutting the combination unit to obtain insoles 100, the reinforcement layer 20 being enclosed between the base 10 and the top layer 30.
  • The reinforcement layer 20 can be latex sponge, rubber sponge or Polyurethane (PU). The top layer 30 can be a piece of fabric or leather.
  • By the method, the insoles 100 can be made in mass production. The number of reinforcement layer 20 and/or top layer 30 can be varied according needs.
  • FIGS. 2 to 4 show the insole 100 made by the method and includes a base layer 11, a reinforcement layer 20 and a top layer 30. The reinforcement layer 20 is attached on the base layer 11 and the top layer 30 is attached on the reinforcement layer 20. The periphery of the underside of the top layer 30 is directly attached on the base layer 11 so as to completely enclose the reinforcement layer 20 between the base layer 11 and the top layer 30. The reinforcement layer 20 does not protrude from the base layer 11 and the top layer 30 so that the reinforcement layer 20 is well protected.
  • The method of the present invention is suitable for mass production without much laboring and therefore is benefit by increasing the manufacturing efficiency and the competitiveness in the market. The reinforcement layer 20 of the insole made by the method of the present invention does not protrude from the base layer 11 and the top layer 30 so that the reinforcement layer 20 is well protected and does not wear out. The combination of the base layer 11 and the reinforcement layer 20 provides proper flexibility and does not deform. The structure of the insole is simple and strong.
  • FIGS. 5 to 7 show another embodiment of the insole wherein the top layer 30 includes a piece of fabric or leather 301 attached to a soft layer 302 which is attached to the reinforcement layer 20. The soft layer 302 is attached on the reinforcement layer 20 and the periphery 31 of the underside of the fabric or leather 301 is attached to the soft layer 302, and the periphery 32 of the underside of the soft layer 302 is attached to the base layer 11. By this arrangement, the reinforcement layer 20 is completely enclosed between the soft layer 302 of the top layer 30 and the base layer 11. The reinforcement layer 20 is well protected and is not damaged. The soft layer 302 provide comfortable wearing feature to the insole 100.
  • While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
