Abstract

A footwear article includes an upper defining apertures spaced apart from one another in a first arrangement. A heel structure has a deformable element attached to a base. The deformable element has pegs spaced apart from one another in the first arrangement and extending through the apertures in the upper. A method of manufacturing a footwear article includes placing a deformable element between an inner layer and an outer layer of an upper and attaching the deformable element to a rigid base. The deformable element includes at least one peg extending outward toward the outer layer. The method includes inserting the peg through the outer layer so that the peg extends through the outer layer and is exposed at an exterior surface of the outer layer. After inserting the peg of the footwear element through the outer layer of the upper, the peg is secured at the exterior surface of the outer layer.

Claims

1. An article of footwear comprising:

an upper including an inner layer and an outer layer, and defining a foot-receiving cavity inward of the inner layer, wherein the outer layer defines at least one aperture;

a heel structure having a deformable element attached to a rigid base, wherein the deformable element is capable of movement between an uncollapsed configuration and a collapsed configuration with respect to the base, wherein the deformable element is disposed between the inner layer and the outer layer and the inner layer is disposed between the deformable element and the foot-receiving cavity; and

at least one peg extending outward from at least one of the deformable element, and the base, and extending through the aperture in the outer layer, wherein the peg is secured at a surface of the upper.

2. The article of footwear of claim 1, wherein:

the outer layer includes a plurality of apertures;

the deformable element includes a medial portion, a lateral portion, and a heel piece;

the at least one peg includes a first peg, a second peg, and a third peg;

the first peg extends outward from the heel piece and is positioned in a respective aperture in the outer layer;

the second peg extends outward from the medial portion and is positioned in a respective aperture in the outer layer;

the third peg extends outward from the lateral portion and is positioned in a respective aperture in the outer layer; and

each of the first peg, the second peg, and the third peg is secured at a surface of the upper.

3. The article of footwear of claim 2, wherein:

each of the first peg, the second peg, and the third peg includes a shaft portion and a head portion of unitary, integral construction with the shaft portion;

the shaft portion extends through one of the apertures of the upper; and

the head portion is bonded at the surface of the upper.

4. The article of footwear of claim 3, wherein the head portion depicts at least one of a number, a letter, a symbol, a logo, an object, or a design.

5. The article of footwear of claim 1, wherein a peg extends outward from a peripheral portion of the rigid base.

6. The article of footwear of claim 1, wherein the deformable element is disposed between the outer layer and the inner layer prior to the attachment of the deformable element to the base.

7. The article of footwear of claim 6, wherein the outer layer incldues a plurality of tabs extending from a lower edge of the outer layer and wherein the tabs are used to secure the upper to the rigid base. The article of footwear of any of claim 6, wherein the outer layer includes a plurality of tabs extending from a lower edge of the outer layer and wherein the tabs are used to secure the upper to the rigid base.

8. The article of footwear of claim 1, wherein:

the base includes an anchor receptacle located on the medial side of the base and another anchor receptacle located on the lateral side of the base;

each of the anchor receptacles includes at least one pin;

the deformable element includes an anchor located on the medial side of the element and an anchor located on the lateral side of the element; and

each of the anchors includes at least one aperture for receiving a respective pin of the anchor receptacle.

9. The article of footwear of claim 1, wherein the deformable element is disposed between the outer layer and the inner layer after the attachment of the deformable element to the base.
