Abstract

The present application discloses footwear comprising a body structure in which at least upper is made of one continuous folded composite material comprised of layered sheets of material.

Claims (25)

1. An athletic shoe comprising:

a unibody shoe upper comprising a pre-cut assembly including:

a plurality of elements pre-cut, layered on top of one another and adhered together to form a continuous composite structure having a stacked arrangement, the continuous composite structure being disposed in a folded configuration having the shape of a footwear with edge portions of the continuous composite structure joined together at a seam to form a permanent shape, the continuous composite structure including:

1) a first layer comprising a first partial layer element;

2) a second layer comprising a first full layer element positioned next to the first partial layer element, the first full layer element including a fabric or mesh material and being larger in overall dimension than the first partial layer element;

3) a third layer comprising an array of individual cushioning pod elements forming a cushioning padding element, the cushioning padding element being stacked onto the first full layer element and being constructed from a different material than the fabric or mesh material of the first full layer element; and

4) a fourth layer comprising an insole element stacked onto the cushioning padding element; and

wherein the first full layer element includes at least one pod fitting aperture sized and positioned to engage a corresponding cushioning pod element.

2. The shoe of claim 1 , wherein the unibody shoe upper has non-uniformity such that a first region of the unibody shoe upper is different than a second region of the unibody shoe upper.

3. The shoe of claim 2 , wherein the non-uniformity is in thickness, texture, stiffness, hardness, color, breathability, shock absorption, resistance to abrasion and/or flexibility.

4. The shoe of claim 1 , further comprising a fifth layer comprising a second full layer element.

5. The shoe of claim 4 , wherein the second full layer element is made of fabric or mesh.

6. The shoe of claim 4 , wherein the second full layer element is made of ethylene vinyl acetate (VA) foam, olefin or polyolefin foam, polyurethane (PU) foam, urethane based foam, thermoplastic foam, or elastomer.

7. The shoe of claim 1 , further comprising an outsole assembly constructed separately from the unibody shoe upper and configured to be attached to the continuous composite structure having the permanent shape.

8. The shoe of claim 7 , wherein the outsole assembly comprises:

sole pod elements;

an outsole layer that is in contact with the bottom of the upper;

a midsole; and/or

an outsole.

9. The shoe of claim 1 , wherein the cushioning padding element comprises a foam material.

10. The shoe of claim 1 , wherein the plurality of elements is adhered together with a hot-melt adhesive.

11. The shoe of claim 1 , wherein the plurality of elements comprising the continuous composite structure have different thicknesses and/or performance characteristics.

12. The shoe of claim 1 , wherein the first full layer element comprises a locking pod aperture ( 25 ) configured to engage a locking pod element ( 22 ) positioned on the cushioning padding element ( 20 ).

13. The shoe of claim 1 , wherein the insole element has at least one aperture formed in a bottom surface thereof, said aperture being sized and positioned to engage a corresponding cushioning pod element.

14. The shoe of claim 1 , wherein the first partial layer element has an extension forming a side element that covers the seam when folded.
