Abstract

An ultra-lightweight sole plate assembly can include a ground engaging outer shell, a structural component, and one or more cleat members. A method of making the outer shell includes thermoforming a foil material such as polyamide. Thermoforming the foil includes applying vacuum to the foil material. Excess foil material can be trimmed from the outer shell. The structural component can be made by injecting a molding material onto the outer shell. The cleat members can be co-molded with the shell during forming of the structural component. The resulting sole plate assembly has a reduced weight with the desired traction, strength and durability.

Claims (33)

1. A method of forming an article of footwear having a sole structure, the method comprising:

forming an outer shell having a first protruding portion extending from a first ground-contacting surface of the outer shell and a second protruding portion extending from the first ground-contacting surface of the outer shell, the outer shell extending continuously from a forefoot end of the sole structure to a heel end of the sole structure and being a unitary component having the first protruding portion, the second protruding portion, and the first ground-contacting surface formed as a single piece;

positioning a structural component within the outer shell, the structural component extending into the first protruding portion and the second protruding portion; providing a first cleat member including a top surface in direct contact with the structural component and a bottom surface disposed on an opposite side of the first cleat member than the top surface and forming a second ground-contacting surface, the first cleat member in contact with the first protruding portion and contained within a wall defined by the first protruding portion such that a distal end of the first protruding portion is flush with the second ground-contacting surface of the first cleat member; and

providing a second cleat member forming a third ground-contacting surface, the second cleat member in contact with the structural component at the second protruding portion and spaced apart from the second protruding portion.

2. The method of claim 1 , further comprising at least partially surrounding the first cleat member with the first protruding portion.

3. The method of claim 1 , further comprising spacing a distal end of the second protruding portion from the second cleat member by the structural component.

4. The method of claim 1 , further comprising providing a third protruding portion extending from the first ground-contacting surface of the outer shell and a third cleat member associated with the third protruding portion, the third cleat member forming a fourth ground-contacting surface.

5. The method of claim 4 , further comprising extending the structural component into the third protruding portion.

6. The method of claim 4 , further comprising contacting the structural component with the third protruding portion and the third cleat member.

7. A method of forming an article of footwear having a sole structure, the method comprising:

forming an outer shell having a first protruding portion extending from a first ground-contacting surface of the outer shell and including a first aperture at a distal end of the first protruding portion; and a second protruding portion extending from the first ground-contacting surface of the outer shell and including a second aperture at a distal end of the second protruding portion, the outer shell extending continuously from a forefoot end of the sole structure to a heel end of the sole structure and being formed as a unitary component having the first protruding portion, the second protruding portion, and the first ground-contacting surface formed as a single piece;

positioning a structural component within the outer shell, the structural component extending into the first protruding portion, extending into the second protruding portion, spaced apart from the first aperture, and extending through the second aperture;

providing a first cleat member including a top surface in direct contact with the structural component and a bottom surface disposed on an opposite side of the first cleat member than the top surface, the first cleat member being received within the first aperture and forming a second ground-contacting surface that is flush with the distal end of the first protruding portion; and

providing a second cleat member attached to the second protruding portion by the structural component, the second cleat member forming a third ground-contacting surface.

8. The method of claim 7 , further comprising spacing the second cleat member apart from the distal end of the second protruding portion by the structural component.

9. The method of claim 7 , further comprising placing the first cleat member in contact with the first protruding portion.

10. The method of claim 7 , further comprising at least partially surrounding the first cleat member with the first protruding portion.

11. The method of claim 7 , further comprising providing a third protruding portion extending from the first ground-contacting surface of the outer shell and a third cleat member associated with the third protruding portion, the third cleat member forming a fourth ground-contacting surface.

12. The method of claim 11 , further comprising extending the structural component into the third protruding portion.

13. The method of claim 12 , further comprising contacting the third cleat member with at least one of the third protruding portion or the structural component.

14. A method of forming an article of footwear having a sole structure, the method comprising:

forming an outer shell having a first protruding portion extending from a first ground-contacting surface of the outer shell, a second protruding portion extending from the first ground-contacting surface of the outer shell, and a third protruding portion extending from the first ground-contacting surface of the outer shell, the outer shell extending from a forefoot end of the sole structure to a heel end of the sole structure and being a unitary component having the first protruding portion, the second protruding portion, the third protruding portion, and the first ground-contacting surface formed as a single piece;

positioning a structural component within the outer shell, the structural component extending into the first protruding portion, the second protruding portion, and the third protruding portion;

providing a first cleat member including a top surface in direct contact with the structural component and a bottom surface disposed on an opposite side of the first cleat member than the top surface and forming a second ground-contacting surface that is flush with a distal end of the first protruding portion, the first cleat member in contact with the first protruding portion and received within and surrounded by the first protruding portion;

providing a second cleat member that is spaced apart from and is attached to the second protruding portion by the structural component, the second cleat member forming a third ground-contacting surface; and

providing a third cleat member that is in contact with the structural component and a distal end of the third protruding portion, the third cleat member forming a fourth ground-contacting surface.

15. The method of claim 14 , further comprising positioning an outer surface of the second cleat member flush with an outer surface of the second protruding portion and an outer surface of the structural component.

16. The method of claim 14 , further comprising providing the first protruding portion with a first aperture, providing the second protruding portion with a second aperture, and providing the third protruding portion with a third aperture.

17. The method of claim 16 , wherein providing the first aperture, the second aperture, and the third aperture includes providing the first aperture at a distal end of the first protruding portion, the second aperture at a distal end of the second protruding portion, and the third aperture at a distal end of the third protruding portion.

18. The method of claim 17 , further comprising extending the structural component through the second aperture.

19. The method of claim 17 , further comprising at least partially surrounding the first cleat member with the first protruding portion at the first aperture.

20. The method of claim 17 , further comprising extending the structural component into the second aperture.

21. The method of claim 20 , further comprising positioning the structural component flush with the distal end of the second protruding portion at the second aperture, the structural component in contact with the second cleat member at the distal end of the second protruding portion.
