FIELD OF THE INVENTION

The field of the present invention generally relates to footwear and, more particularly, to footwear having a heel counter.

BACKGROUND OF THE INVENTION

Shoes and boots often have a heel counter that used to stiffen the material around the heel and to give support to the foot. The heel counter can be a piece of leather forming the back of the shoe or boot but more often the heel counter is placed on the inside of the shoe or boot between the lining and the leather outsole. The heel counter is typically shaped to extend around the heel to hold the heel in place and provide stability so that it does not shift or slip. A high counter sometimes aids in keeping the foot from rolling over the side of the shoe or boot.

While heel counters are intended to provide rigidity, they often are too rigid which can irritate or injure the wearer's heel. Accordingly, there is a need for improved footwear with heel counters.

For example, the present invention is suitable for other types of footwear such as, for example, western boots, outdoor boots, duty or military boots, shoes, and the like.

Referring now to the drawings, FIGS. 1 to 4 show footwear in the form of a work boot 10 having an external heel counter 12 according to the present invention. The illustrated boot 10 is adapted for use on a right foot but it is noted that a similar but mirror image boot adapted for the left foot is used in conjunction with the illustrated boot 10 for form a pair of the boots 10. The illustrated boot 10 includes a sole 14 forming the bottom of the boot 10 and extending below the boot wearer's foot and an upper 16 extending upward from the sole 14 to cover the boot wearer's foot and a small portion of their lower leg.

The illustrated upper 16 is secured to the sole 14 with a welted construction where the upper 16 is stitched to the sole 14 using a welt 18. The welt 18 is a strip of leather or synthetic material which extends about the periphery of the upper 16 at the interface between the upper 16 and the heel counter 12 with the sole 14. The upper 16 and the heel counter 12 are stitched to the welt 18 with thread and the welt 18 is in turn stitched to the sole 14 with thread to secure the upper 16 and the heel counter 12 to the sole 14. It is noted that upper 16 and/or the heel counter 12 can alternatively be secured to the sole 14 using any other suitable construction such as, for example, a cemented construction where the upper 16 and/or heel counter is glued to the sole 14 with adhesive, or the like.

The illustrated outsole 14 includes an outsole 20 forming an exterior bottom surface for the sole 14 and an insole (not visible) located above the outsole 20 and forming an upper interior surface of the sole 14 upon which the boot wearer's foot rests within the upper 16. It is noted that the sole 14 can also include a midsole located between the outsole 20 and the insole and/or a shank forming an arch support within the sole 14. The outsole 20 is the outermost portion of the sole 14 of the boot 10 and forms the bottom surface of which is exposed to wear. The illustrated bottom surface of the outsole 20 is provided with tread. The illustrated outsole 20 is molded of synthetic polymer material but can alternatively can comprise any other suitable material such as, for example, rubber, leather or the like. The insole can be attached to the outsole 20, the midsole, the upper 16, and/or welt 18 or the insole can be removable and/or replaceable. The insole can form the upper most surface on the inside of the bottom of the boot or it can be covered with a sock lining of suitable material. The midsole can be located between the outsole 20 and the insole. The midsole can be molded of synthetic polymer material but can alternatively can comprise any other suitable material. The midsole is designed to provide the boot 10 with desired characteristics of cushioning, support, and flexibility. The shank can form the arch support which supports the arch of the boot wearer's food and can comprise steel, fiber, wood, and/or plastic. It is noted that the sole 14 can alternatively have any other suitable construction within the scope of the present invention.

The illustrated upper 16 includes a vamp 22 which covers the top and front portion of the boot wearer's foot, a counter or quarter 24 that encloses the heel or rear portion of the boot wearer's foot and is secured to the rear of the vamp 22, and a shaft 26 which fits around the lower leg of the boot wearer's leg and is secured to the top of the vamp 22 and the quarter 24. The shaft 26 has an upper edge which forms an upper opening through which the wearer's foot enters the boot 10. The illustrated vamp 22 and the shaft 26 cooperate to form an opening 28 at the forward end of the boot 10 that is closed by a lace 30 so that the opening 28 can be tightened to secure the boot 10 to the wearer's foot and loosened to ease entry and exit of the wearer's foot. The illustrated vamp 22 and the shaft 26 are provided with a plurality of eyelets 32 and hooks 34 for the lace 30 as is known in the art. A tongue 36 is also provided at the laced opening as is also known in the art. It is noted that the upper 16 can also comprise a lining within its interior. The lining typically comprises pigskin, glove leathers, a heavy twilled cotton or linen fabric, and the like. Additionally, the lining can comprise synthetics such as, for example, Gortex, Sympatex, and the like to provide waterproof and/or sweat dissipating characteristics to the boot 10. It is noted that the upper 16 can alternatively have any other suitable configuration.

The illustrated components of the upper 18 comprise leather such as, for example, cowhide, pigskin, horsehide, kangaroo skin, and the like but any other suitable material can alternatively be utilized such as, for example exotic leathers or skins, synthetic leather or other synthetic materials, cloth, and the like. The illustrated components of the upper 18 are secured together by stitching but any other suitable means can alternatively be utilized.

The illustrated heel counter 12 is an external heel counter. That is, the heel counter 12 forms a portion of the exterior surface of the boot 10. The illustrated heel counter 12 is located at a rear of the upper 16 and is configured to be located behind a heel of the boot wearer's foot and to not extend along lateral sides of the heel of the boot wearer's foot.

As best shown in FIGS. 5 and 6, the illustrated heel counter 12 is generally hour class shape. The illustrated heel counter 12 has a substantially straight bottom edge 38, an arcuate and convex top edge 40 opposite the bottom edge 38, and opposed arcuate and concave lateral side edges 42 connecting the bottom and top edges 38, 40. The concave lateral sides 42 provide some flexibility to the rigid heel counter 12. It is noted that the illustrated top edge 40 has a lateral width larger than the later width of the illustrated bottom edge 38 so that the heel counter 12 does not extend along lateral sides of the heel of the boot wearer's foot but partially extends along lateral sides of the boot 10 above heel of the boot wearer's foot. Configured in this manner, an upper portion of the illustrated heel counter 12 extends forwardly above the heel of boot wearer's foot (best shown in FIGS. 2 and 3) to lock the heel of boot wearer's foot in place. The illustrated hour glass shape is effective to lock the top of the ball of the boot wearer's heel and the bottom but allows the center to be more flexible. It is noted that the heel counter 12 can alternatively have any other suitable shape.

The illustrated heel counter 12 is formed of a material more rigid than the material forming the portions of the upper 16 adjacent the heel counter 12. The heel counter 12 preferably comprises a polymeric material, more preferably comprises rubber, and even more preferably comprises molded rubber. It is noted that rubber has great abrasion resistant properties, holds its shape well without being too rigid or hard on the boot wearer's heel. It is noted however, that the heel counter 12 can alternatively comprise any other suitable material and/or can be formed in any other suitable manner. The illustrated heel counter 12 is molded such that an external surface 44 of the heel counter 12 is provided with a plurality raised ridges 46. The illustrated ridges 46 laterally extend and are vertically spaced-apart one above the other. The illustrated ridges 46 are triangular shaped in a vertical cross-section to form a sharp rear outer edge (best shown in FIG. 6). The illustrated ridges 46 are also triangular shaped in a horizontal cross-section to form a sharp rear outer edge (best shown in FIG. 8). Configured in this manner, the ridges 46 operate to reduce scuffing of the external rear surface 44 of the heel counter 12 which often occurs when removing boots.

The illustrated external heel counter 12 is located at the rear of the upper 16 with the bottom edge 38 secured to the sole 14 via the welt 18 via stitching with threads and the top and lateral side edges 40, 42 are secured to adjacent portions of the upper 16 via stitching with threads. The illustrated top edge 40 is secured to an adjacent portion of the shaft 26 while the illustrated side edges 42 are secured to adjacent portions of the quarter 24. In the illustrated embodiment, some of the portions of the upper 16 adjacent the heel counter 12 are stitched over the heel counter 12 and some of the portions of the upper 16 adjacent the heel counter 12 are stitched under the heel counter 12. The illustrated top edge 40 is secured over the adjacent portion of the shaft 26 (best shown in FIG. 7) while the illustrated side edges 42 are secured under the adjacent portions of the quarter 24 (best shown in FIG. 8). That is, the illustrated the adjacent portion of the shaft 26 is secured under the top edge 40 (best shown in FIG. 7) while the illustrated the adjacent portions of the quarter 24 are secured over side edges 42 (best shown in FIG. 8). It is noted that the configuration of the upper 16 and/or the configuration of the connections between the upper 16 and the heel counter 12 can be in any other suitable manner.

Any of the features or attributes of the above the above described embodiments and variations can be used in combination with any of the other features and attributes of the above described embodiments and variations as desired.
