Description
- This application claims the priority benefit of U.S. Provisional Application 61/927958 filed Jan. 15, 2014, which is herein incorporated by reference in its entirety.
- This disclosure is related to shoe insert devices. More particularly, the disclosure discusses a device and method to secure a person's heel within a shoe and prevent the heel from slipping out of the shoe.
- The statements in this section merely provide background information related to the present disclosure. Accordingly, such statements are not intended to constitute an admission of prior art.
- Many times when walking with shoes, a person's heel can slip out of one of the shoes. In some cases, the person's heel doesn't re-enter the shoe properly. This can be painful to the person and can also damage the shoe. This phenomenon occurs especially frequently with women's high heeled shoes. Since a different shoe design is not always preferable, there exists a need to better secure a person's heel to the shoe or at least properly guide the heel back into the shoe.
- In one embodiment, the device to secure a person's heel to a piece of footwear and properly guide the heel back into the footwear comprises: an elastic band that comprises a bottom section, a left-side section, a right-side section, and a heel section.
- In an alternate embodiment, the left-side section comprises a front left arm and a back left arm, and the right-side section comprises a front right arm and a back right arm.
- In an alternate embodiment, the heel section has a raised surface configured to increase a frictional resistance between the device and the footwear.
- In an alternate embodiment, the bottom section further comprises a top cloth cover on a top portion of the bottom section and a bottom cloth cover on a bottom portion of the bottom section.
- In an alternate embodiment, the bottom cloth cover is configured to attach to an insole of a shoe.
- In an alternate embodiment, the device further comprises a shoe.
- In an alternate embodiment, the band further comprises one or more nub(s) attached to a top of the heel section. The nub(s) can be a rhinestone, rubber stop, or the like.
- In an alternate embodiment, the device further comprises a thin layer of fabric on top of the bottom section, wherein the thin layer of fabric is configured to keep a foot comfortable. The thin layer of fabric can be a breathable material.
- In an alternate embodiment, the device further comprises a thin layer of foam beneath the front section, wherein the thin layer of foam is configured to distribute shear forces more evenly at the shoe insole. Alternately, the material of construction can be rigid plastic or the like instead of foam.
- In an alternate embodiment, the device further comprises a hook and loop fastener (e.g. Velcro®) which is configured to attach the device to the shoe insole.
- In an alternate embodiment, the shoe insole is not required and the elastic band is configured to attach directly to the interior of a shoe insole assembly.
- In an alternate embodiment, the elastic band further comprises a clasp which is configured to vary the length of the elastic band.
- The elastic band mid-section material of construction can be cloth or another material which has a higher frictional coefficient than cloth. This decreases slippage of the elastic band and helps the wearer keep their foot in the shoe. Note that the elastic band mid-section does not have to be elastic. Its purpose is to maintain contact with the heel, while the elastic portion provides force.
- The elastic band maintains force on the heel in a predominantly forward direction, with an increasing amount of force in the downward direction as the foot exits the shoe. This increasing downward force helps to guide the foot back into the shoe when necessary.
- The anchors that attach the device to the shoe may be clasps, ties, Velcro®, or any adhesive, or some combination thereof. The means to attach the elastic strap to the anchors can Velcro®, clasps, ties, or adhesives, or the like.
- A method to use an embodiment of the device described above comprises: affixing the bottom section to a shoe insole assembly; and inserting a person's foot into the device.
- The scope of the invention is defined by the claims, which are incorporated into this section by reference. A more complete understanding of embodiments on the present disclosure will be afforded to those skilled in the art, as well as the realization of additional advantages thereof, by consideration of the following detailed description of one or more embodiments. Reference will be made to the appended sheets of drawings that will first be described briefly.
- A clear understanding of the key features of the invention summarized above may be had by reference to the appended drawings, which illustrate the method and system of the invention, although it will be understood that such drawings depict preferred embodiments of the invention and, therefore, are not to be considered as limiting its scope with regard to other embodiments which the invention is capable of contemplating. Accordingly:

FIG. 2 is a perspective bottom view of a device according to one embodiment. -
FIG. 3 shows a device according to one embodiment integrated with a shoe. -
FIG. 4 is a device according to one embodiment with nubs and integrated with a shoe. -
FIG. 5 is an exploded view showing the device attached to a shoe insole. -
FIG. 6 is a cut-away view showing the device in a retracted position. -
FIG. 7 is a cut-away view showing the device in a stretched position while the shoe and device are being worn around the heel of a wearer. -
FIG. 8 is a perspective view of the device according to another embodiment. - As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.
- There are several examples of prior art related to this present application. The most common can be found in any shoe store, or pharmacy, and is generally referred to as a heel pad or heel grip. This product is unsatisfactory, while it makes the shoe tighter, it does not establish a connection between the foot and the shoe. These products oftentimes exacerbate the problem by causing blisters and rubbing on the constrained foot. Several inventors have tried to overcome the shortcomings of this design, and these are their patents.
- While prior art designs have tried to provide a way of retaining the wearer's heel in a shoe, these prior art designs are not functional for a majority of shoe designs. For example, there are several prior art designs that are required to loop around an anchor point, such as the “heel” of a high-heeled shoe in order for this design to function properly and effectively. One can only attach this invention to a shoe with a clearly defined high heel thereby limiting its scope of use to only one type of shoe. Another limiting factor for these prior art designs is that this strap is designed to be worn “around” the shoe and is consequently very visible and may distract from the original design of the shoe. Additionally, the straps that are worn outside the shoe only provides vertical tension between foot and heel, creating a downward force but not a forward force.
- Other prior art designs that are designed to be located inside of shoes and include an elastic strip designed to be attached only to the shoe counter. These designs provide minimal retention and do not provide downward force for retaining the wearer's heel within the shoe.
-
FIG. 1 is a perspective top view of theheel retention device 100 according to one embodiment of the present application. Theheel retention device 100 includes aheel section 101, a frontleft arm 102, a backleft arm 103, a frontright arm 104, a backright arm 105, atop cloth cover 106 on a top portion of the bottom section (hidden), abottom cloth cover 107 on a bottom portion of the bottom section (hidden), and a raisedsurface 108 on theheel section 101. The left and right sides are symmetrical and left and right sides have been identified based on the view of the drawings from the viewer's point of view, however when the device is worn the right and left sides may be reversed, however the left and right sides are symmetrical and can be interchanged depending on the point of view in relation to the device. - The
heel retention device 100 is an elastic retainer that can be made of stretchy rubber, elasticized cloth, or stretchy plastic, it may be a solid band or several smaller bands interwoven, or a net-like structure. In another embodiment, theheel retention device 100 can be constructed of a thermoplastic elastomer or like material with a Shore-A value between 10 and 30. In one embodiment, the Shore-A value is approximately 18. For the purposes of this disclosure, the Shore-A of a material is determined using the ASTM D2240 Type A standard; or of a like-performing cloth elastic, urethane, or rubber. The tensile strength at break is 600 psi and the tensile elongation at break is 600% as determined by the test method ASTM D412. Theheel retention device 100 may be formed to be transparent, opaque, or colored. - The
heel section 101, the frontleft arm 102, and the frontright arm 104 are joined together to form a firstU-shaped loop 120 defining an opening end for receiving the wearer's heel and foot. In an un-stretched or retracted position, loop may be have half-circle, half-diamond, half-ellipse, or any other suitable shape. The shape ofheel retention device 100 may increase the surface area which is in contact with the heel, increasing friction and decreasing slippage between theheel retention device 100 and the wearer's heel. - The
heel section 101 and the left backarm 103 and right backarm 105 are also joined to form a secondU-shaped loop 124. The backleft arm 103, and backright arm 105 function to exert a primarily downward force on the foot into the receiving shoe cavity. The twoback arms top cloth 106. In another embodiment, they do not form a continuous loop and separate ends attach to the sole assembly at various points forward of the shoe counter. - The
heel retention device 100 also includes a raisedsurface 108 formed along arearward surface 112 of theheel section 101. In one embodiment, the raisedsurface 108 is formed of a plurality of raised protrusions that extend from the rearward surface that is otherwise generally smooth. The raisedsurface 108 on theheel section 101 functions to exert a frictional resistance between therearward surface 112 of theheel section 101 and the inside of the shoe counter, making it less likely that the foot and/or theheel retention device 100 will come up and out of the back of the shoe cavity.
