Patent Application
20210112920
The present invention relates generally to orthotic insoles and footwear and, more particularly, to orthotic sole and insole devices, systems, methods, and computer readable media for use with high heel footwear.
It may be desirable to make high heel shoes and other footwear more comfortable, by redistributing weight and/or improving foot posture within the footwear, using an orthotic sole or insole device.
In the prior art, there may have been a number of gimmicks which may have promised but afforded little or no functionality in this respect. Many such gimmicks, including off-the-shelf ones offered at drug stores and elsewhere, may have failed to consider or incorporate a medical assessment component relating, for example, to particular individual users' biomechanics, foot type, unique foot anatomy, and/or medical histories.
Some prior art shoe inserts may have afforded some help but, notwithstanding claims to the contrary, may have failed to effectively help stop the user's foot from sliding forward. Such inserts may have been provided with a toe crest that did not work with certain types of shoes, such as those with front straps and those with insufficient room in toe box portions thereof. Such inserts also may have failed to shift the user's weight to the back of their heel and away from their forefoot.
Similarly, other prior art insoles may have been formed from a clear resin material. While such insoles were designed in an effort to slow the user's foot from falling forward in their shoe, they may have failed to splay the user's toes, lift their metatarsal heads, adequately and accurately support their arches (e.g., the medial longitudinal arch, transverse arch, and lateral longitudinal arch), unload high pressure areas of their foot, and/or redistribute the user's weight.
These and other inserts and insoles may have also suffered from a further limitation in that their intended design was for permanent placement into the user's shoes, without affording the user with any ability to move them over to their other shoes.
Reinforced heel orthotic inserts may have been known in the prior art. They may have been designed to reduce impact at the heel, referencing the calcaneus or heel bone. In this respect, they may have substantially nothing to do with, and/or may be completely different than, the present invention.
Other high heel shoe devices of limited comfort may have been known in the prior art. While they may have been designed for use as (or with) high heels, they may have failed to afford sufficient comfort and/or a ready ability to conform to the shape of the user's shoe pitch and/or slope line, for example, to accommodate minor nuances. The shape of such devices may not have been designed and/or matched to the user's heel pitch and/or slope line. Heel pitch refers to the angle of the midsole from the heel to the flexpoint of the shoe, typically measured in degrees. Slope line refers to the curvature observed of the midsole from heel to flexpoint of the shoe. They also may have failed to afford sufficient space for the user's first metatarsal joint, which typically may be enlarged; and/or they may have failed to provide a cutout for the user's first metatarsal-phalangeal joint that effectively assists in mechanical loading through the forefoot.
What may be needed are orthotic sole and/or insole devices, systems, methods, and/or computer readable media for use with high heel footwear. (For example, computer readable media may be needed or desired to record—and/or, operatively, to encode one or more computer processors to help implement or perform—one or more features, inter-workings, and/or steps that are depicted or discussed herein in the context of the devices, systems, and/or methods according to the invention.)

As best seen in
According to preferred embodiments of the invention, the devices, systems, methods, and/or computer readable media are preferably adapted for use in combination with assessment of related medical factors and the user's weight and height. The systems, methods, and/or computer readable media according to preferred embodiments of the invention involve and/or provide for precise measurement (e.g., sub-millimeter dimensions and measurements) of the user's feet and high heel footwear which are preferably taken by 3D scan or photogrammetry. The orthotic insoles according to the invention are preferably medically designed to change biomechanical weight distribution and position, and total body alignment.
Substantially precise and/or exact dimensions, measurements, specs, and/or other information—including 3D scans of the user's feet in weight-bearing and/or neutrally corrected (calcaneal vertical, sub-talar neutral, with rearfoot and forefoot neutrally positioned to the user's anatomical alignment) non-weight bearing configurations—are preferably transferred digitally for manufacture of the insoles according to the invention. In manufacturing methods, according to the invention, this information is preferably imported to CAD/CAM software on computer readable media to prepare it for output to a CNC milling machine, additive manufacturing/3D printing, and/or other system.
The insole base portion is preferably milled, from an EVA block, using a CNC milling machine, or from a renewable source used in additive manufacturing, and/or other system according to the invention. According to the invention, the EVA blocks may preferably have standard dimensions of about 5.5 inches, by about 1.25 inches, by about 13.25 inches. The EVA blocks preferably have a Shore Type A or Type OO durometer hardness in the range of between about 30 and about 50. (The scope of the present invention extends to encompass, instead or in addition, 3D printing of the base portion from EVA or another material.)
After milling, the blocks are preferably shaped as insoles and/or hand-finished with a top-cover portion that is preferably applied and secured thereto by a manual gluing process. (The scope of the present invention extends to encompass, instead or in addition, applying the top-cover to the base portion by an automated gluing process.)
The top-cover portion for each insole is preferably formed from pre-cut pieces and/or a roll of top-cover material. One or more logos may be pre-printed (e.g., in a zinc-coloured ink) on the top-cover material. The top-cover material preferably has antibacterial properties. It is preferably embedded with silver ions, and is preferably breathable, with an absorption capacity of preferably about 8 times its weight in water. The top-cover material preferably affords comfort and dryness properties with its thermo-regulating effect as aforesaid. It is preferably substantially abrasion, tear, and/or rip resistant under both dry and humid (or wet) conditions. The top-cover material may preferably be embedded with a natural Eucalyptus aroma, and preferably keeps its aroma when washed in temperatures of up to about 30° C. It is preferably anti-allergic and does not generate odors. The top-cover material preferably has a thickness of about 0.75 millimeters. It is preferably relatively light, flexible, and comfortable (as compared, for example, with pigskin). The top-cover material is grindable and can be readily worked with. It is similar to real leather but with increased strength.
The top cover portion preferably, in addition to helping the foot breathe, provides a high grip surface that may help keep the foot from sliding forward inside the user's high heel footwear.
After manufacture, finished orthotic insole devices according to the invention may preferably be fit on the user's foot and in specific footwear, and minor adjustments may be performed if necessary.
Accordingly, some features, elements, parts and/or steps that preferably work together according to (or in association with) the invention may include a medical assessment of the user's needs, 3D scans, correct and/or appropriate footwear, digital design and manufacture of an orthotic insole device, and a professional fitting. Some of the invention's features, elements, parts, steps, and/or sub-combinations thereof may be altogether new, including the built-in heel stopper, the sunken heel cup, and one or more combinations of features, including the EVA base portion and the top cover portion, along with a medical assessment, digital design and manufacture, and dispensing.
In use, some advantages of the invention, over the prior art, may include one or more of the following: (a) its utility in obviating or mitigating one or more disadvantages or shortcomings associated with the prior art, in meeting or providing for one or more desires, benefits, needs or advantages, or in achieving one or more objects of the invention; (b) its customization and tailoring to each particular user, preferably being moulded to the unique shape of their foot; (c) its custom fit to specific footwear; (d) its compliance and adherence to medically sound principles of design and use; (e) its coverage of the entire foot; and/or (f) its ability for transfer to other (similar structure) high heel footwear.
The EVA and Poron™ materials, according to the invention, preferably afford significant comfort advantages for the user's foot and substantially/readily conform to the shape of the user's shoe pitch and slope line, with an ability to accommodate minor nuances.
The 3D scans, according to the invention, are preferably highly accurate.
One or more features and functionalities of the invention are preferably offered under or in association with the applicant's distinctive PITCH PERFECT trademark.
The invention is contemplated for use by or in association with insoles, soles, and footwear. The invention, however, is not so limited. Other embodiments, which fall within the scope of the invention, may be provided. For example, the invention encompasses full 3D prints of high heel footwear (or any portions thereof) complete with one or more of the aforementioned features of the invention
