Shoe with Heel Cutout

Abstract

A shoe comprising an inner lining, upper portion, and optionally a heel counter in between the inner lining and upper portion. A cutout is positioned at the heel of the shoe, that cuts out the inner lining, upper portion, and heel counter where the shoe's heel comes into contact with the top of the calcaneus bone and above. The empty space from the cutout is replaced with a heel cutout filler that has some degree of stretchiness. The inner lining, upper portion, and heel cutout filler are stitched together to form the heel of the shoe.

[0015] FIG. 7 is a side perspective view of a shoe with a heel cutout from FIG. 6.

DETAILED DESCRIPTION

[0016] As shown in FIG. 2, a conventional shoe has a heel counter 100 that is designed to thoroughly cover the heel area around the calcaneus bone. The heel counter 100 is generally tall enough to cover most, or all, of the posterior heel portion of a person's foot. The calcaneus bone contains the starting point of the Achilles tendon, which attaches the calf and its muscles to the heel. As such, the heel counter 100 generally covers the lower portion of the Achilles tendon.

[0017] FIG. 3 shows an embodiment of a shoe with a heel cutout. The heel cutout is comprised of having a cutout on the inner lining 330, heel counter 320, and upper 310. The heel cutout is positioned such that it removes the heel counter 320 from the top of the calcaneus bone, and above. This is where the start of the Achilles tendon resides, and this is often where discomfort can arise from the stiffness and rigidity of the heel counter. In this embodiment, the cutout is similar to a U shape.

[0018] Creating a shoe with a heel counter cutout can be performed by either, taking a conventional shoe and retroactively generating the cutout, or by manufacturing the shoe with the heel counter cutout already having the cutout. When retrofitting a conventional shoe with a heel cutout, the stitching at the top edge of the shoe, which holds the inner lining 330 and upper 310 is unstitched at the rear of the shoe. This allows for the heel counter 320 to be exposed. The heel counter 320 may be removed from the shoe, to perform the cut out, or the heel counter 320 may be cut out while in the shoe. The inner lining 330 and upper 310 are also cut with a corresponding cutout.

[0019] After all the materials have the necessary cutout, then the heel counter 320 is reassembled back into the shoe. An elastic, soft material in the same shape as the cutout is used to fill the void generated from the cutout. This heel cutout filler 410 is stitched into the shoe. The stitching seals the inner lining 330 to the upper 310 together, while also stitching the heel cutout filler 410 to the shoe. This stitching also helps to hold and lock in the heel counter 320 within the shoe. An embodiment of a shoe with a heel counter cutout can be seen in FIG. 4 and FIG. 5. The heel cutout filler 410 provides significantly improved comfort for the wearer's heel, and can also serve to provide elasticity for limited expansion of the shoe's heel portion. The heel cutout filler 410 can be a single layer of material, or can be multiple layers. The heel cutout filler 410 can be made from various materials that are stretchable, such as elastics, stretchable fabric, stretchable PU (polyurethane), and stretchable leather. A material with at least 10% stretch is preferred, and other embodiments may have varying degrees of stretch.

[0020] In other embodiments, the heel cutout may vary in shape other than the U shape from FIG. 4 and FIG. 5. FIG. 6 and FIG. 7 show another embodiment with a different heel cutout shape. Though the heel cutout shape is different, the heel cutout is still positioned such that it removes the heel counter from the top of the calcaneus bone, and above. The heel cutout filler 610 is catered to the heel cutout shape, as seen in FIG. 6 and FIG. 7. The heel cutout filler 610 covers the void from the heel cutout, and more in the case of the embodiment in FIG. 6 and FIG. 7. A larger than necessary heel cutout filler 610 may be done for various reasons, such as aesthetics, manufacturing convenience, or increased comfort.

[0021] In another embodiment, a shoe may not have an internal heel counter. The inner liner and upper portion may be made of materials that are sufficiently rigid enough to provide heel support. In this embodiment, a heel cutout may still be desired, and can be created by having an inner liner cutout and upper portion cutout. The heel counter cutout would not be necessary as there is no heel counter. A heel cutout filler may be stitched to the inner liner cutout and upper portion cutout as in other embodiments.

[0022] Although the present invention has been described in detail with respect to certain embodiments and examples, variations and modifications exist which are within the scope of the present invention as defined in the following claims.
