FIELD OF INVENTION

This invention relates to orthopedic inserts for shoes, more particularly, to customizable orthopedic inserts for shoes and a method of manufacturing and activating the customizable insert for a particular user quickly and efficiently.

BACKGROUND

The human foot is a unique structure that can be very flexible or very rigid when a person walks. The human foot has twenty-six bones and thirty-three joints that are connected by a plethora of muscles, tendons, and ligaments. Thus the internal locking and unlocking of the bones and joints in the person's foot will not work properly if there is abnormal alignment. If such an abnormal alignment is present, the muscles in the lower extremities will be required to work harder to control the alignment of bones and joints. As a consequence, these muscles will fatigue quicker. And, once the muscles fatigue, the person will experience pain and discomfort because the muscles can no longer compensate for the abnormal alignment of the foot and ankle.

Many developments have been made in the prior art that address abnormal alignment of the foot and ankle. Besides invasive surgery, sole inserts for shoes have been developed for alignment issues. Often, these inserts are positioned between the bottom or plantar aspect of a person's foot and the shoe. The custom sole inserts are designed to support the bones and joints, maintain the normal alignment, and redistributes the pressure exerted by a person's body weight upon the plantar aspect of the foot so that the person can walk with greater stability and comfort.

A typical method known in the prior art for manufacturing customize sole inserts requires a plaster cast of the foot of the person or patient that is then used to customized the sole inserts along with any required modifications according to the specific needs of the patient as determined by the attending podiatrist. This type of procedure is expensive, and requires a substantial amount of time between the initial plaster cast and the final product, sometimes on the order of weeks. Therefore, a patient must endure the pain of improper alignment until the insert is made to the satisfaction of the attending podiatrist. Also, due to the expense, a patient normally cannot afford additional inserts and will typically use the same insert when wearing different shoes, which may be unhygienic and may create new alignment issues.

More recent prior art has attempted to address the problems associated with the expense and time for making a custom inserts. U.S. Pat. No. 7,017,218 illustrates a method for making a custom insert using water injected through a syringe to react with a woven polyurethane casting material. A disadvantage of the disclosure provided in U.S. Pat. No. 7,017,218 issued to Nguyen is that the water injection system requires additional tools, i.e., the injector, to be inserted into and through the layers, which may hurt and damage the user or the custom insert if the injector is improperly used or handled.

There is a need for customizable shoe inserts that can be formed and cured faster based on the user's needs and current shoes. There is also a need for a ready to use insert that requires less tools to form the shoe inserts.

OBJECTIVES

To provide a method for making and customizing a sole insert for a shoe quickly using a layer of moldable material which can be permanently hardened once a customized shape is obtained. To provide a sole-insert specific to the needs and requirements of a patient. To provide an insert which is not expensive to manufacture, and, as a consequence, a user may be able to afford to purchase multiple inserts for other shoes worn by the user. To reduce the need for a supervising podiatrist. And, to allow the user to customize the sole insert at a time and place of the user's choosing.

In some embodiments, the top and bottom layers 20, 40 may be a flexible plastic that may be perforated to produce the first and second sets of the plurality of holes 22, 42, which may allow passage for the fluid 5.

In most embodiments, referring to FIG. 2, the top and bottom layers 20, 40 along with the first and second sets of the plurality of holes 22, 42 may be covered with cloth material layers 24, 44. In most embodiments, the cloth material layers 24, 44 may be made from any type of fabric known in the art that may be permeable, so as to allow for the transfer of the fluid 5 or moisture to the top, middle, and bottom layers 20, 30, 40. In most embodiments, the cloth material layers 24, 44 may be made from cotton, denim, felt, linen, nylon, polyester, silk, satin, twill, wool, yarn, etc., or a combination thereof.

In most embodiments, the top layer 20 may be a cushioning material to support the foot 1. In most embodiments, the top layer 20 may be various thicknesses and may be varied in thickness through the top layer 20. In a non-limiting example, the top layer 20 may have a heel portion that may be thicker than a ball portion to better support the heel of the foot 1, as seen in FIG. 2. In most embodiment, the top layer 20 may be made with materials such as cloth, fabric, leather, foam, or any synthetic materials used in footwear industries, or a combination thereof. In most embodiments, the cushioning material of the top layer 20 may be compressible for improved comfort for the user. In some embodiments, the cushioning material may compress under the force or weight of the foot 1 when applied to the sole insert 10 and may partly decompress when removing the foot 1 from the sole insert 10.

In a preferred embodiments, the top layer 20 may be perforated with the plurality of holes 22 by hand or machine, including but not limited to a sewing machine, a mechanical press, a thermal press, a punch, a laser, or a combination thereof, to produce the first set of the plurality of holes 22. In a preferred embodiment, the first set of the plurality of holes 22 may be 1-3 mm in diameter. In some embodiments, the top layer 20 may use an alternative to plastic materials that may be an absorbent material with micro perforations. In most embodiments, the plurality of holes 22 may be space equally apart, in rows, at random, or in a designed pattern, or a combination thereof. In another embodiments, the top layer 20 may not be a perforated material as long as the bottom layer 40 may be sufficiently perforated.

In most embodiments, the moldable middle layer 30 may have a minimum thickness so that the moldable middle layer 30 may contour to an adjacent plantar aspect area 2, i.e., sole, of a user's foot 1. In most embodiments, the moldable middle layer 30 may come in contact with the fluid 5, which may be an accelerant, such as water or moisture within the shoe 3. In most embodiments, the fluid 5 may be applied by a sponge, a paper towel, a cloth towel, a spray bottle, and/or a combination thereof, which may be applied at least one of the top layer 20 or the bottom layer 40. In other embodiments, the fluid 5 or moisture may be the user's perspiration or sweat from the foot 1. In another embodiment, the fluid 5 may be a fast acting chemical accelerant. In most embodiments, after the moldable middle layer 30 contacts the fluid 5, the moldable middle layer 40 may permanently harden to conform to the adjacent plantar aspect area 2 of the foot 1. In most embodiments, the moldable middle layer 30 may be constructed from a hardening compound that may be made from various types of chemical or materials, such as potting compounds, epoxy, resins, fiberglass, fiberglass resin, etc., or a combination thereof.

In the preferred embodiment, the hardening compound may be fiberglass for desired fiberglass properties, such as strength, durability, activation speed, and ease of activation by water or ambient moisture. In most embodiments, the moldable middle layer 30, which may be constructed from the fiberglass material, may be imprinted with the adjacent plantar aspect area 2 by pressing with the foot 1 against the sole insert 10. In most embodiments, a custom foot shape 15, as illustrated in FIG. 3 as a shaded region, may permanently form in the sole insert 10 after the hardening compound, i.e., fiberglass resin, cures after contact with the fluid 5, such as moisture from an accelerant, produced by the wearer's foot 1, and/or ambient condition in the shoe 3. In most embodiments, the custom sole insert 10 may be placed in an airtight, moisture-free package to maintain freshness and to prevent unnecessary hardening.

In most embodiments, since the middle layer 30 may be constructed of various materials, a hardening agent or an accelerant used may depend on the material of the middle layer 30. In another preferred embodiment, a preferred material may be a polyurethane casting material such as that disclosed in U.S. Pat. No. 4,433,680 issued to Yoon and improved upon in U.S. Pat. No. 6,007,505 issued to Grim et al. The improvement under Grim et al. may be the addition of hydroxypropyl methyl-cellulose (HPMC), which may prevent urethane from becoming sticky when contacted with water. The preferred material according to Grim et al. may be sealed in a package and may be pliable if kept within the package or shortly after being removed. In most embodiments, the preferred material contact with the fluid 5, i.e., water, may accelerate the hardening process, but the preferred material may harden at ambient conditions without the addition of water, although at a slower rate.

In other embodiments, an alternative material that may be used as the middle layer 30 may be at least one constructed from fiberglass fabric impregnated with a water hardenable material as disclosed in U.S. Pat. No. 5,334,442 issued to Okamoto et al. The middle layer 30 may be construct of materials known in the art and not limited to the materials disclosed in the present invention. In most embodiments, other suitable materials may be used so long as said materials may be adapted to be formed to the plantar aspect area 2 of a user's foot 1 and harden to formed the custom foot shape 15 in a short period of time. In some embodiments, the middle layer 30 may be comprised of a material that may not harden at ambient conditions without first coming into contact with an activation agent, the accelerant, or the fluid 5.

In most embodiments, a required thickness of the middle material layer 30 may vary and may depend upon shoe size, width, arch height, and material considerations. In some embodiments, the required thickness may be one or more thickness sizes, as seen in FIG. 2, where a heel region may have a greater thickness than a ball region of the foot 1. In most embodiments, the required thickness may be prepackaged according to shoe size, width, arch height, and material considerations. In a non-limiting example, the wearer may be able to purchase a pair of sole inserts 12 at a drug store based on a shoe size of 8-10 and a low arched foot profile with increased heel support, i.e., the required thickness for the heel region may be 10-15 mm while the low arched foot profile may have the required thickness of about 3-5 mm. In the preferred embodiment, the preferred material may be the polyurethane casting material and hydroxypropyl methyl-cellulose material that may have a thickness range of 1-15 mm, but most preferably between 3-4 mm. In some embodiments, the insert may be limited to a general area adjacent to and about the arch of the foot 1 or may extend entire length of the foot 1, including the adjacent plantar aspect area 2, as seen in FIGS. 1-3. In another preferred embodiment, the middle moldable layer 30 may extend from under the foot 1 from the heel to a metatarsal or toe areas.

In most embodiments, the bottom layer 40 may be constructed from various types of materials such as plastics, leather, foams, etc., or a combination thereof. In most embodiments, the bottom layer 40 may have a second set of the plurality of holes 42. In a preferred embodiment, the second set of the plurality of holes 42 may be 1-3 mm in diameter. In another embodiment, the second set of plurality of holes 42 may be spaced in rows of larger holes that may be 10-15 mm in diameter expanding outwards from a center of the moldable bottom layer 40. In other embodiments, the second set of the plurality of holes 42 may be comprised of both the 1-3 mm and the 10-15 mm diameter holes in any type of pattern or at random on the bottom layer 40. In some embodiments, the bottom layer 40 may use an alternative to plastic materials that may be an absorbent material with micro perforations. In most embodiments, the second set of the plurality of holes 42 may be constructed in a similar manner as the first set of the plurality of holes 22.

In most embodiments, the plantar aspect area of the wearer's foot 1 may be imprinted on to the molding middle layer 30 as the wearer walks. In most embodiments, once the middle layer 30 may have hardened, the bottom layer 40 may retain or conform to the shape of the wearer's foot 1 permanently in conformity with the molding middle layer 30. In these embodiments, the bottom layer 40 may be a moldable bottom layer.

In most embodiments, the shape of the sole insert 10 may be personalized to fit certain types of foot deformities or foot shapes by adding a padding support 50, as seen in FIG. 2, to certain areas on the foot 1 that may realign the foot 1 in a certain direction during the molding phase or provide additional support to the sole insert 10 for a sufficient period of time. In some embodiments, the padding support 50 may have a third plurality of holes 52, not shown, that may allow for the fluid to pass through. The third plurality of holes may have properties similar to the first and second plurality of holes 22, 42. In most embodiments, the padding support 50 may be any size, shape, thickness, and/or malleable property that may conform with the size, shape, and thickness of the sole insert 10. In a non-limiting example referring to FIG. 2, the padding support 50 may be placed near the heel portion of the bottom layer 40 to improve shock absorbance for the user when the sole insert 10 is used with athletic shoes. In this example, the user may be purchasing the sole insert 10 in conjunction with a sports activity like basketball or soccer. The prepackaged sole insert 10 may be specialized for a sport category of use and may be advertised as such.

In most embodiments, the bottom layer 40 may provide an upward normal force so that the moldable middle layer 30 may be sandwiched between the upward normal force of the bottom layer 40 and a downward force the foot 1 that may be applied to the top layer 20. In most embodiments, the bottom layer 40 may be constructed from various types of materials, such as foam, elastic bandages, vacuum suction cups, plastics, etc., or a combination thereof. In the preferred embodiment, the bottom layer 40 may be constructed from plastic materials because the plastic materials may be flexible and occupy much less volume in the shoe 3. In most embodiments, as seen in FIG. 2, the bottom layer 40 may sufficiently perforated to allow the fluid 5 or moisture to be absorbed into the moldable middle layer 30.

In most embodiments, the bottom layer 40 may cover the foot 1 from the heel region to an area under the ball region of the foot 1. In most embodiments, an inside surface of the bottom layer 40 may have a cavity 46 that may be fitted to the moldable middle layer 30. In most embodiments, the bottom layer 40 may have a narrow rim 48 around the cavity 46 for attachment to the top layer 20. In some embodiments, the narrow rim 48 may have an adhesive that may adhere to at least one side 38 of the moldable middle layer 30 and/or to a perimeter 28 of the top layer 20 as shown in FIG. 2. In some embodiments, the rim 48 of the bottom layer may be formed to be a soft and flexible material to avoid wrinkles that may form along a medial and lateral area of the sole insert 10. In other embodiments, the rim 48 may have a plurality of cuts that may absorb the wrinkles along the medial and lateral area of the sole insert 10.

In some embodiments, the sole insert 10 may include the additional padding 50 as a heel seat that may cover an area around the heel. In some embodiments, the heel seat may be positioned below the middle layer 20 and above the bottom layer 40. In some embodiments, a top surface of the heel seat may be constructed as a rounded surface or or a flat surface about a central area of the heal seat to provide more stability to the user while he or she may be standing and applying a downward force with the foot 1.

Assembly

The method for construction and activating the insert sole 10 will now be described. In most embodiments, the top, middle, and bottom layers may be preconstructed or preformed, where the rim 48 of the bottom layer 40 and the perimeter 28 of the top layer 20 may be attached about their respective periphery or perimeter, preferably with an adhesive, a glue, and/or epoxy. In most embodiments, before the top and bottom layers 20, 30 are sealed, the middle layer 30 may be inserted between the top layer 20 and the bottom layer 40. In other embodiments, the top and bottom layers 20, 40 may be sealed on at least one side before the the middle layer 30 may be inserted. In some embodiments, the padding support 50 may be positioned on the inside surfaces of the top layer 20 and the bottom layer 30, as seen in FIG. 2. In a preferred embodiments, the adhesive, the glue, and/or the epoxy may be applied to the top, middle, and bottom layers 20, 30, 40 to maintain all three layers 20, 30, 40 as a single sole insert 10.
