CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority of U.S. Provisional Patent Application No. 60/963,350 filed 3 Aug. 2007, the entire contents of which is hereby incorporated by reference.

FIELD OF THE INVENTION

The present invention relates generally to a shoe insert, and in particular to a malleable form-fitting shoe insert that can adjust to fit various sizes and styles of shoes.

BACKGROUND

Shoetrees and shoe inserts have been used to maintain the shape of footwear for many years. When shoes sit idle without a firm foot substitute in place, they will naturally begin to fall out of shape and often become ruffled and wrinkled. Generally, a shoe insert solves this problem by occupying the front tip of the shoe to support the structure of the shoe. As such, a shoe insert is important for the long term care of the shoe, as it serves to reduce the amount of creases in the fabric of the shoe and helps to maintain the shoe's overall shape after continued wear.
As footwear designs have become more plentiful, so has the range of designs of shoetrees and shoe inserts available to support them. The market contains an assortment of shoetrees and shoe inserts of various shapes and materials, each typically designed for use with a specific shoe type. Among those materials are plastic, recycled formed paperboard, wood and/or plastic with spacer bar compositions, and molded tissue paper. Each of these materials have some disadvantages.
A shortfall of many currently used shoe inserts is that they are not capable of supporting a variety of shoe shapes and sizes. For example, recycled formed paperboard and plastic inserts are rigid and offer no compression that would allow them to form to the shape of a shoe. Pre-formed shoe inserts are custom molded and thus generally only fit the style of shoe they were packaged with. Wood and spacer bar shoe inserts are capable of achieving varying lengths, however the toe member they use for engaging the front portion of the shoe is fixed and has no compression to accommodate different toe boxes. Additionally wood and spacer bar shoe inserts require mechanical embodiments that are not easily engaged in the shoe and generally only accommodate loafer-style shoes and cannot be used with heels, flats, boots or sandals.
Another shortfall of many currently used shoe inserts is that they are not durable. For example, molded tissue paper inserts are made from thin tissue paper that decomposes rapidly after repeated insertion into a shoe. Recycled formed paperboard inserts are rigid and break easily. Likewise, hollow plastic inserts offer some compression but are prone to breakage after repeated use.
What is needed therefore is a shoe insert capable of use with a wide variety of shoe types.

SUMMARY OF INVENTION

It is the objective of the present invention to provide a shoe insert that will accommodate shoes of a variety of shapes and sizes. It is a further objective of the present invention to provide a shoe insert that is both durable and reusable.
In one embodiment a shoe insert in accordance with the present invention includes a moldable, malleable, compressible, form-fitting material that allows the shoe insert to take on the shape of interior portions of a variety of shoes of different shapes and sizes.
In one embodiment the shoe insert includes a toe portion, a vamp portion and a rear portion that can be inserted into the toe portion of a shoe.
In another embodiment, the shoe insert includes a toe portion, a vamp portion and a heel portion, that create a malleable foot shape.
In a further embodiment, the shoe insert includes a toe portion, a vamp portion, a heel portion and a vertical portion in the shape of a foot and lower leg. The toe portion, vamp portion, and heel portion are made of a malleable material.

DETAILED DESCRIPTION

The following exemplary embodiments disclose shoe inserts that feature the use of a compressible, malleable, moldable form-fitting material. Polyurethane, polyurethane foam, ethylene vinyl acetate (EVA), thermo moldable foam, memory foam, rubber, a fabric sack filled with beads, PVC foam (polyvinyl chloride), EPE foam (polyethylene), latex foam, silicon gel, an antimicrobial material such as polyolefin, or some combination of these materials may be used to constitute the compressible, moldable material. The aforementioned list is merely illustrative, as other compressible, moldable materials are known and would be obvious to one of ordinary skill in the art. Likewise, the present invention is directed towards a shoe insert, and the word “shoe” is understood to refer to all footwear, including, but not limited to, dress shoes, casual shoes, pumps, flats, high heels, sneaker boots, sandals, wedge sandals, platform shoes, loafers, boat shoes, boots, slippers, sneakers, golf shoes, ballet shoes, and ballroom shoes.
Referring now in detail to the figures, wherein like reference numerals represent like parts throughout the several views, one exemplary embodiment is shown in FIGS. 1A and 1B, which illustrates a shoe insert 100. The shoe insert 100 includes a vamp portion 104 that is connected to both a toe portion 102 and a rear portion 106. The shoe insert 100 is made of a unitary construction of a compressible, malleable, moldable form-fitting material, which allows the shoe insert 100 to occupy a toe portion of a range of shapes and sizes of shoes by forming to the contours it encounters. As shown in FIG. 1C, once the shoe insert 100 is inserted into the toe portion of a shoe, the toe portion 102 engages the toe portion of the shoe, and the vamp portion 104 engages the vamp portion of the shoe, allowing the shoe insert 100 to exert pressure on the walls of the shoe, maintaining the shape of the shoe. The rear portion 106 may have either a planar or an indented face. In exemplary embodiments, the shoe insert 100 may contain either a fragrance and/or an antibacterial.
Turning now to FIGS. 2A and 2B, which also illustrate that the shoe insert's 100 moldable, form-fitting material allow the shoe insert 100 to take on a variety of shapes. FIG. 2C further illustrates that the shoe insert 100 can accommodate a shoe of different shapes and sizes. FIG. 1C and FIG. 2C show that the shoe insert 100 is useful for, although not limited to, shoes with heels, as it can form to pointed toe shoes such as that shown in FIG. 1C, or rounded toe shoe, such as that shown in FIG. 2C, and is in neither case obstructed by the rising heel of the shoe.
Another exemplary embodiment is depicted in FIG. 3, which shows a shoe insert 300 that includes a vamp portion 304 that is connected to a toe portion 302 and a rear portion 306.

The extension member 808 may be made of any rigid material, including, but not limited to metal, wood, plastic, cardboard, or stone. The toe member 802 is directly connected to the vamp member 804 which form a front member 803. The front member 803 is connected to the heel member 806 through the extension member 808. When inserted into a shoe, the front member 803 of the shoe insert 800 will engage the toe portion of a shoe, while the heel member 806 of the shoe insert 800 will engage the heel portion of a shoe. Since the front member 803 and heel member 806 are both made from a form-fitting material, the shoe insert 800 is useful for, but not limited to, a variety of shoes with heels.
In another exemplary embodiment, the extension member 808 is movably affixed to the front member 803. The connection between the front member and the extension member may be a ball and socket joint, a hinge, or any other joint that allows for movement, such connections would be known to those skilled in the art. When the extension member 808 is free to move relative to the front member 803, it allows the heel member 806 to take adopt different vertical and horizontal positions as depicted by FIGS. 8B and 8C. This allows shoe insert 800 to accommodate a greater range of shoes, from flat-bottomed to heeled shoes.
Another exemplary embodiment is depicted in FIG. 9, which shows a shoe insert 900 that includes a vamp member 904 that is connected to a toe member 902 and a heel member 906.
