Description

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is related to and claims priority from prior provisional application Ser. No. 62/211,695, filed Aug. 28, 2015, entitled “ADJUSTABLE ARCH SUPPORT SYSTEM”, the contents of all of which are incorporated herein by this reference and are not admitted to be prior art with respect to the present invention by the mention in this cross-reference section.

FIELD OF THE INVENTION

The present invention relates generally to an insole arch support system for use in female designer shoes, but can also be used in men's and children's shoes. More specifically, the present invention relates to a customizable arch support system allowing the wearer to personally tailor the arch support to their specific foot arch height by selecting a molded arch support insert that best conforms to the wearer's unique foot arch.

BACKGROUND OF THE INVENTION

Orthotic devices are typically contoured, plate-like structures which fit in a shoe so as to correct or control the position and function of the foot. These orthotic devices are of a fixed design once manufactured, and are no longer configurable once they are made. Since the most critical functions of the foot generally involve the heel and mid-foot portions, a degree of rigidity is required in these areas in order for the device to carry out its biomechanical purposes. Hence, many devices of this type have a rigid, inflexible plate or cap which extends from the heel of the foot through the mid-foot, and sometimes generally extending to the metatarsal heads, known as the ball of the foot. Thus, they are typically only useful in flat or mostly flat-soled shoes.
The construction of these devices often presents a problem from the standpoint that this makes the device too thick for use in many types of shoes. Particularly in the area of women's high-heeled shoes where the interior volume is extremely limited and the rigidity does not allow these devices to fit over the steeply contoured shape of women's high-heeled shoes. A custom, rigid orthotic device may become problematic when fitting into shoes having an elongated shaft or throat, such as boots. The additional thickness of the insole when using a custom orthotic device may limit the footwear designer's ability to maintain a sleek, thin, fashionable look.
Further, any additional thickness applied to the interior volume sole of the shoe may result in discomfort or injury. A custom device may be too wide or too narrow to fit the wearer's foot comfortably when inserted in the shoe. In particular, tightness of the vamp of the shoe may lead to nerve damage, injuring the wearer. To go without support of the arch of the foot can result in severe cramping of the abductor hallucis, which will draw in the adjacent flexor muscles, resulting in pain and inability to perambulate.
If the arch of the foot is not properly supported, a wearer may exhibit none of the traditional symptoms of over-pronation (foot posture) until presenting with pain, which may be in the knees or lower back. The source of discomfort may be hidden within the foot, leading to misdiagnosis and potential further injury. Of particular concern is a wearer with an existing injury that seems to resolve until using a high-heeled shoe, exacerbating the injury and prolonging length of treatment for relief.
A fixed design, un-configurable custom orthotic would be prescribed; however, the needs of a recovering injury can change minutely or drastically, rendering the cost of a custom orthotic prohibitive to resolution if frequent changes are needed by the wearer. Further, conditions such as pregnancy may change the size and shape of a woman's foot daily, making a fixed design, un-configurable custom orthotic impractical, and potentially harmful to the wearer.
Fashionable shoes may also be designed to have a narrow toe. If the load of the body weight is not distributed appropriately, with the aid of an appropriately sized arch, the toes may be compressed into the shoes by the weight of the body, which may lead to permanent deformation of the toes as they conform to their environment.
Accordingly, there exists the need for an orthotic insole having minimal thickness and still provides a solution for the variability of the arch in the foot among different wearers, or the changing need of a single wearer, while remaining fashionable in the field of heeled shoes.

BRIEF SUMMARY OF THE INVENTION

The present invention overcomes the problems cited above by providing an insole, which may be integral to the shoe or may be separate, and is configured to removably attach an arch support insert into a fastening system in the mid-foot arch portion of the insole. A plurality of arch support inserts are available such that the wearer may choose to use the insole without an arch support insert or fasten the appropriate sized and shaped arch support insert to the insole. Current additive manufacturing and 3D scanning technology makes it possible to provide affordable, completely customizable arch support inserts. An arch support insert cover is provided to protect the arch support insert from the wearer's bare feet. Because the insole and arch support contain a fastening means, the arch support insert remains correctly positioned on the mid-foot arch of the insole during use in any type of footwear, including women's high-heeled shoes. A properly fitted insole with the insert attached will disperse the weight equally upon the bones and ligaments of the foot, giving balance to the wearer along with improved spinal health; hence, an overall positive impact on the body as a whole.
The customizable arch support system comprises a shoe insole that is configured to allow the addition of a removably attached arch support insert. A plurality of differently sized and shaped arch supports are provided to fit the specific arch in the wearer's foot. A fastening means is used to attach said arch support inserts to said insole of the shoe. Covers are provided that will be positioned above the insole and arch support insert in the shoe. The arch support insert is removably attached to the insole via a fastening means, preferably a snap-type fastening system. However, other fastening means may be used, such as hook and loop fasteners, double-sided adhesive tape, or other fastening means. The arch support insert is available in a plurality of arch configurations ranging from a low arch to a high arch, or individually customized, so that it may accommodate the specific wearer's arch.
The insole is thin when compared to other arch support systems while remaining configurable and still applicable to the steeply down-curved platform found in women's fashionable high-heeled shoes. A shank conforms to the curve of the shoe under the heel and arch of the foot, and provides structural integrity to aid in supporting and distributing the wearer's body weight from ball of the foot, through the arch, to the heel of the foot. By selecting an appropriate insert, this arch support system will result in a shoe insole that inherently provides greater body stability and balance to the wearer by distributing body weight over the entire foot, thereby lessening the pressure on the metatarsal heads, the ball of the foot and the heel cup within the shoe.
The following preferred embodiment of the present invention describes the position and configuration and construction of the elements of the invention, which are an insole, a snap-type fastening system, an arch support insert and a cover. The insole is comprised of several layers of material and at least one female snap-type fastener to construct an insole that conforms to the curvature of a steeply down-curved arch typical in women's high-heeled shoes. A shank is located on a first layer of fiberboard and synthetic adhesive along the centerline of the mid-foot area. A preferably flexible cellulose board layer is then placed on top of the first insole layer with a synthetic adhesive layer, with at least one female snap-type fasteners set into the material. The layers are crimped and shaped to conform to the inside of the shoe. Then, a layer of the synthetic adhesive material is placed on the flexible cellulose board layer and a microcellular urethane cushioning layer(s) is placed on the synthetic adhesive layer that has been configured and adapted by cut-outs to reveal the female snap-type fasteners. The insole layers may be made of a variety of shock absorbing materials. U-shaped gel or polymer material pads are adhered in the heel portion of the insole and formed to cup the heel of the foot. The heel cup may extend upward into the shoe to reduce and customize the heel volume for narrower heel widths. Finally, after the shoe is constructed, a cover or sock liner of leather or synthetic material, with circular cut-outs to leave the at least one snap-type fastener exposed, is adhered to the top of the insole layers. This creates a cushioning insole that will accept attachment of the arch support insert while not taking up too much space within the tight confines of typical women's fashion high-heeled shoes.
The fastening means that attach the arch support insert to the insole is preferably comprised of a typical snap-type fastener system, further comprising an at least one male snap-type fastener fitting into an at least one female snap-type fastener. Alternately preferably, other types of fastening systems may be used such as hook and loop fastening system, among others.
The arch support insert is comprised of a compressible, cushioning material molded to conform to the arch of the mid-foot and at least one male snap-type fastener permanently attached to the bottom of the arch support insert. The compressible, cushioning material is preferably covered with a leather or lightweight synthetic fabric, possibly with a layer of gel or urethane foam between the cushioning material and the cover. Alternately preferably, a leather, or mesh material may be used to protect the compressible, cushioning material from body oils and other contaminants.
The arch support insert is preferably formed from ethylene-vinyl acetate (EVA). Alternately preferably, the arch support insert may be formed from polyurethane (PU) foams, silicone, nylon or Santoprene-brand thermoplastic vulcanizates (a thermoplastic elastomer), or similar materials. The arch support insert is molded to generally conform to a human being's foot arch in various arch heights and lengths. At least one male snap-type fastener corresponds to at least one female snap-type fastener located in the insole to removably attach the arch support insert to the insole of the shoe.
A cover is comprised of a durable material is structured and arranged to cover or envelope the arch support insert to protect the arch support insert from the wearer's foot. The material of the cover may be comprised of leather, canvas or other durable material on top of the arch support insert, and a flexible fabric, leather, or mesh-type material to wrap around the arch support insert and hold the cover in place. Alternatively, the cover may be multiple pieces of a durable material with the at least one male snap-type fastener located to correspond to the matching at least one female snap-type fastener. The arch support insert may be covered with a top layer of durable material with no cover on the underside or sandwiched between two layers of durable material with the cover preferably stitched around the perimeter.
The arch support insert is available in many different sizes to match a wearer's mid-foot arch size. Among the many different sizes available, the insert will function to support a low arch, medium arch, high-arch, or be customizable to the wearer's specific foot. A wearer will simply select the arch support insert size that best fits their individual foot, place the cover around the arch support insert, and fasten the covered arch support insert to the insole of the shoe. Alternatively, the wearer will select the appropriate arch support insert with the cover already attached and fasten it to the insole of the shoe.
In an alternate embodiment, the insole is further comprised of additional gel inserts, or similar-type cushioning materials, that are located at the ball of the foot and in the heel cup areas for further cushioning within the insole of the shoe. Due to the nature of women's high-heeled shoes, more pressure is placed on the ball of the foot because of the steeply-arched downward curvature of the shoe from heel to toe. This causes the ball of the foot to bear greater pressure because of the intimate contact of the ball of the foot and the heel within the shoe. By providing a gel insert in the area of the ball of the foot and the heel cup combined with the arch support insert, less pressure will be applied to these areas while wearing a high-heeled shoe, and such pressure that is applied will be dispersed by the gel inserts.
A method of providing customizable arch support in fashionable women's high-heeled shoes comprising the steps of: selecting an arch support insert based on wearer's particular arch in the mid-foot region, and attaching said arch support insert to an insole using a snap-type fastening system.
