Abstract

An article of footwear may have an upper and a sole structure secured to the upper. The upper includes an illuminable panel and a plurality of strands positioned to extend adjacent and parallel to the illuminable panel. The illuminable panel has a surface with a covered area and an exposed area. The covered area includes a substantially opaque covering, and the exposed area is at least partially visible from the exterior of the footwear. The strands are located to correspond with the exposed area of the illuminable panel. Light from the exposed area of the illuminable panel may enhance, highlight, or otherwise increase the visibility of the strands or areas of the upper that include the strands.

Claims

1. An article of footwear having an upper and a sole structure secured to the upper, the upper comprising:

an illuminating panel that emits light, the illuminating panel having a first surface and an opposite second surface, the first surface being oriented to face toward an exterior of the footwear, and the second surface being oriented to face toward an interior of the footwear, the first surface having a covered area and an exposed area, the covered area including a substantially opaque covering disposed on the first surface of the illuminating panel and blocking light emitted by the illuminating panel, and the exposed area being at least partially visible from the exterior of the footwear; and

a plurality of strands positioned to extend adjacent and parallel to the illuminating panel, the strands being located to correspond with the exposed area of the illuminating panel;

wherein at least a portion of the illuminating panel is removed from the covered area, forming one or more apertures extending through the illuminating panel, thereby reducing the covered area of the illuminating panel to be illuminated, thus saving energy.

2. The article of footwear recited in claim 1, wherein the one or more apertures are located separate from the exposed area.

3. The article of footwear recited in claim 1, wherein the exposed area includes a plurality of elongate linear portions.

4. The article of footwear recited in claim 3, wherein the plurality of elongate linear portions extend from a lace region of the upper to a region where the sole structure is joined to the upper.

5. The article of footwear recited in claim 4, wherein at least one of the one or more apertures is elongate and extends along the one or more elongate linear portions of the exposed area.

6. The article of footwear recited in claim 1, wherein the plurality of strands are disposed on a same side of the first surface as the substantially opaque covering.

7. The article of footwear recited in claim 1, wherein the plurality of strands are disposed on an opposite side of the first surface as the substantially opaque covering.

8. The article of footwear recited in claim 1, wherein the illuminating panel is an electroluminescent panel.

9. The article of footwear recited in claim 1, wherein the strands resist stretch of the upper.

10. An article of footwear having an upper and a sole structure secured to the upper, the upper comprising:

an illuminating panel that emits light, the illuminating panel having a surface with a covered area and an exposed area, the covered area including a substantially opaque covering on the surface of the illuminating panel and blocking light emitted by the illuminating panel, and the exposed area being at least partially visible from an exterior of the footwear;

a cover layer extending adjacent to the surface of the illuminating panel and forming at least a portion of an exterior surface of the upper, the cover layer being formed from an at least semi-transparent material; and

a plurality of strands located in the exposed area;

wherein at least a portion of the illuminating panel is removed from the covered area, forming one or more apertures extending through the illuminating panel, thereby reducing the covered area of the illuminating panel to be illuminated, thus saving energy.

11. The article of footwear recited in claim 10, wherein the one or more apertures are located separate from the exposed area.

12. The article of footwear recited in claim 10, wherein the exposed area includes a plurality of elongate linear portions.

13. The article of footwear recited in claim 12, wherein the plurality of elongate linear portions extend from a lace region of the upper to a region where the sole structure is joined to the upper.

14. The article of footwear recited in claim 13, wherein at least one of the one or more apertures are elongate and extend along the one or more elongate linear portions of the exposed area.

15. The article of footwear recited in claim 10, wherein the illuminating panel is an electroluminescent panel.
