Shoe insert and method for using same

1. A shoe insert comprising:

a base layer having a top and a bottom surface, wherein the base layer is comprised of a thermoplastic polymer,

a middle layer having a top and a bottom surface, wherein a first portion of the bottom surface of the middle layer is adhered to the top surface of the base layer,

a top layer having a top and a bottom surface, wherein the bottom surface of the top layer is adhered to the top surface of the middle layer,

a bottom layer having a top and a bottom surface, wherein the bottom surface of the base layer is adhered to the top surface of the bottom layer, wherein a second portion of the bottom surface of the middle layer is adhered to the top surface of the bottom layer,

wherein the base layer, middle layer and top layer cooperate to define a main body portion,

wherein the main body portion includes a heel cup, an arch portion and a forefoot portion, wherein the forefoot portion comprises a front part of the middle layer, a front part of the top layer, a front part of the bottom layer and no part of the base layer,

wherein the main body portion includes a border portion that extends at least partially around the base layer, wherein the border portion comprises a border part of the bottom layer, a border part of the middle layer, a border part of the top layer, and no part of the base layer, wherein the border part of the bottom layer is adhered to the border part of the middle layer, and wherein the border part of the middle layer is adhered to the border part of the top layer, and

wherein the border portion has an outside edge, wherein the main body portion includes a flare portion that extends outwardly from the outside edge of the border portion in a transverse direction and is adjacent the arch portion, wherein the flare portion comprises a flare part of the bottom layer, a flare part of the middle layer, a flare part of the top layer, and no part of the base layer, wherein the flare portion includes a top surface and a bottom surface, wherein the top surface of the top layer is coplanar with the top surface of the flare portion, and wherein the bottom surface of the bottom layer is coplanar with the bottom surface of the flare portion.

2. The shoe insert of claim 1 wherein the base layer is comprised of polypropylene.

3. The shoe insert of claim 2 wherein the middle layer is made of ethylene-vinyl acetate foam.

4. The shoe insert of claim 3 wherein the top layer is made of ethylene-vinyl acetate foam.

5. The shoe insert of claim 4 wherein the bottom layer is made of suede.

6. The shoe insert of claim 1 wherein the shape of the arch portion is molded into the base layer prior to adhering the bottom and middle layers thereto.

7. The shoe insert of claim 1 wherein the main body portion comprises a soft portion that surrounds the base layer.

8. The shoe insert of claim 1 wherein the base layer includes a front edge, a rear edge and a length, wherein a raised portion is defined in the base layer, wherein the raised portion begins at the front edge and extends rearwardly toward the rear edge, wherein the raised portion extends less than half the length of the base layer and is adapted to be positioned adjacent a wearer's 2-4 metatarsal bones when the insert is positioned in a properly fitted shoe.

9. The shoe insert of claim 8 wherein the forefoot portion includes a front edge, and wherein the front edge is adapted to only extend to adjacent a wearer's sulcus when the insert is positioned in a properly fitted shoe.

10. The shoe insert of claim 1 wherein the base layer is adapted to be actively molded to the shape of a wearer's foot during use.

11. The shoe insert of claim 10 wherein the base layer is adapted to be actively molded to the shape of a wearer's foot during use as a result of the wearer's body heat and weight changing the shape of the base layer.

12. The shoe insert of claim 11 wherein the base layer is adapted to be actively molded to the shape of a wearer's foot due to both ground reactive force pushing on the shoe insert and the wearer's body heat, whereby the shoe insert is formed into a neutral appliance.

13. The shoe insert of claim 1 wherein the base layer is a single layer.

14. A shoe insert comprising:

a base layer having a top and a bottom surface, wherein the base layer is a single layer comprised of polypropylene,

a middle layer having a top and a bottom surface, wherein a first portion of the bottom surface of the middle layer is adhered to the top surface of the base layer,

a top layer having a top and a bottom surface, wherein the bottom surface of the top layer is adhered to the top surface of the middle layer,

a bottom layer having a top and a bottom surface, wherein the bottom surface of the base layer is adhered to the top surface of the bottom layer, wherein a second portion of the bottom surface of the middle layer is adhered to the top surface of the bottom layer,

wherein the base layer, middle layer, bottom layer and top layer cooperate to define a main body portion,

wherein the main body portion includes a heel cup, an arch portion and a forefoot portion, wherein the forefoot portion comprises a front part of the middle layer, a front part of the top layer, a front part of the bottom layer and no part of the base layer, wherein the shape of the arch portion is molded into the base layer prior to adhering the bottom and middle layers thereto,

wherein the main body portion includes a border portion that extends at least partially around the base layer, wherein the border portion comprises a border part of the bottom layer, a border part of the middle layer, a border part of the top layer, and no part of the base layer, wherein the border part of the bottom layer is adhered to the border part of the middle layer, and wherein the border part of the middle layer is adhered to the border part of the top layer,

wherein the border portion has an outside edge, wherein the main body portion includes a flare portion that extends outwardly from the outside edge of the border portion in a transverse direction and is adjacent the arch portion, wherein the flare portion comprises a flare part of the bottom layer, a flare part of the middle layer, a flare part of the top layer, and no part of the base layer, wherein the flare portion includes a top surface and a bottom surface, wherein the top surface of the top layer is coplanar with the top surface of the flare portion, and wherein the bottom surface of the bottom layer is coplanar with the bottom surface of the flare portion, and

wherein the base layer is adapted to be actively molded to the shape of a wearer's foot during use.
