The present disclosure relates generally to orthotic devices. More particularly, the present disclosure relates to orthotic footwear and insoles.
Foot and toe deformities, such as hallux valgus (commonly known as bunions), hammertoe, and/or overlapping toes, are frequently encountered problems caused by wearing poorly fitting shoes. These conditions can lead to significant discomfort, pain, limitations in mobility, and permanent disfigurations that cause uneven distribution of strain on muscles and tendons that may affect the entire leg and hip. Individuals suffering from such deformities often resort to corrective devices, specialized footwear, or even surgical interventions to address these issues.
Conventional solutions for toe deformities typically involve the use of external toe separators or spacers. These are typically separate accessories or devices that are placed between the toes to encourage proper alignment. While these external devices can offer relief, they often come with notable drawbacks. External toe separators can be cumbersome and inconvenient to use daily, especially within regular shoes. Additionally, some individuals find these external accessories uncomfortable to wear for extended periods, as they may cause pressure points, friction, or irritation between the toes. Some users may also feel self-conscious about wearing devices that are visible when worn with open-toe shoes. Since the effectiveness of external separators varies depending on the user's willingness and adherence to wearing them consistently, these drawbacks may render such devices ineffective.
What is needed is a discreet orthotic positioning apparatus that integrates an insole with built-in toe separators, thereby eliminating the need for external accessories. Additionally, what is needed is an orthotic positioning apparatus that maintains proper toe alignment, effectively preventing the progression of foot deformities. Beneficially, the orthotic positioning apparatus would enable easy access to the shoe's interior while providing a clear view of the toe separators to enhance convenience. Finally, what is needed is an orthotic positioning apparatus that facilitates progressively increasing the spacing between toe separators to accommodate users' evolving needs and comfort levels.
According to one aspect of the present disclosure, an orthotic positioning apparatus includes a shoe extending along a longitudinal axis. The shoe includes an interior, an exterior upper, a foot opening, and a toe box. The exterior upper includes a perimeter edge defining an elongate opening extending between the toe box and the foot opening. An insole is removably disposed within the interior and includes a top surface, a bottom surface, a toe area to receive a user's toes, and multiple resilient toe separator elements projecting from the top surface along an arc. When the insole is disposed within the interior of the shoe, the resilient toe separator elements are positioned within the toe box. Each of the resilient toe separator elements has a width configured to separate adjacent ones of the user's toes by a predetermined distance.
A cover is configured to cover the elongate opening. The cover includes a top edge pivotally coupled to the toe box, and a bottom edge. The cover is configured to selectively pivot upwardly in an open configuration such that the elongate opening exposes the resilient toe separator elements in the open configuration.
In some embodiments, the perimeter edge includes a pair of lateral edges disposed parallel to the longitudinal axis and separated by a distance substantially corresponding to a width of the toe area. The orthotic positioning apparatus may further include one or more stabilization elements extending substantially perpendicularly between the pair of lateral edges. In some embodiments, the stabilization element obstructs at least a portion of the elongate opening. The stabilization element may be adjustable and/or removable.
In some embodiments, the shoe and/or the insole includes a heel configured to provide zero-drop. In some embodiments, the cover includes an attachment portion disposed adjacent to the bottom edge. In certain embodiments, the exterior upper includes an engagement element configured to selectively engage the attachment portion.
In some embodiments, the insole includes a predetermined space between adjacent resilient toe separator elements such that the predetermined space is configured to accommodate one of the user's toes. In certain embodiments, the predetermined space is between about 1.0 cm and about 1.8 cm. In some embodiments, each of the resilient toe separator elements includes an oblong shape extending along an axis parallel to the longitudinal axis. In certain embodiments, each of the plurality of resilient toe separator elements includes a height greater than or equal to the predetermined space. In some embodiments, the height ranges between about 1.0 cm and about 2.2 cm. In some embodiments, the width of each of the plurality of resilient toe separator elements is less than the predetermined space.
In some embodiments, each of the resilient toe separator elements extends through the insole between the bottom surface and the top surface. In some embodiments, the insole further includes a connector strip coupled to the resilient toe separator elements. The connector strip may be substantially planar and each of the plurality of resilient toe separator elements may project upwardly from the connector strip. In certain embodiments, the connector is substantially rigid such that the connector strip provides support and stability to the plurality of resilient toe separator elements. In some embodiments, the bottom surface of the insole comprises a recess configured to accommodate the connector strip.
According to another aspect of the present disclosure, an orthotic positioning system includes a shoe, a first stage insole, a second stage insole, and a cover. The shoe extends along a longitudinal axis and includes an interior, an exterior upper, a foot opening, and a toe box. The exterior upper includes a perimeter edge defining an elongate opening extending between the toe box and the foot opening.
The first stage insole is removably disposed within the interior and includes a first top surface, a first bottom surface, a first toe area configured to receive a user's toes, and first resilient toe separator elements projecting upwardly from the first top surface along a first arc. When the first stage insole is disposed within the interior of the shoe, the first resilient toe separator elements are positioned within the toe box. Each of the first resilient toe separator elements includes a first width configured to separate adjacent ones of the user's toes by a first predetermined distance.
The second stage insole is configured to selectively replace the first stage insole. The second stage insole includes a second top surface, a second bottom surface, a second toe area configured to receive the user's toes, and second resilient toe separator elements projecting upwardly from the second top surface along a second arc. When the second stage insole is disposed within the interior of the shoe, the second resilient toe separator elements are positioned within the toe box. Each of the second resilient toe separator elements includes a second width configured to separate adjacent ones of the user's toes by a second predetermined distance. The second predetermined distance is greater than the first predetermined distance.
The cover is configured to selectively cover the elongate opening and includes a top edge pivotally coupled to the toe box, a bottom edge, and a pair of side edges extending between the top edge and the bottom edge. The cover is configured to selectively pivot upwardly to an open configuration such that the elongate opening exposes the first plurality of resilient toe separator elements or the second resilient toe separator elements in the open configuration.
In some embodiments, the first stage insole and the second stage insole each include a connector strip coupled to the first resilient toe separator elements and the second resilient toe separator elements, respectively. The connector strip may be substantially planar. The first resilient toe separator elements and the second resilient toe separator elements, respectively, may project upwardly from the connector strip such that the connector strip provides support and stability to the first resilient toe separator elements and the second resilient toe separator elements, respectively.
In the drawings, like elements are depicted by like reference numerals. The drawings are briefly described as follows.
The present disclosure now will be described more fully hereinafter with reference to the accompanying drawings, which show various example embodiments. However, the present disclosure may be embodied in many different forms and should not be construed as limited to the example embodiments set forth herein. Rather, these example embodiments are provided so that the present disclosure is thorough, complete and fully conveys the scope of the present disclosure to those skilled in the art.
As discussed above, foot and toe deformities are frequently caused by wearing poorly fitting shoes. These conditions can lead to significant discomfort and permanent disfigurations that cause uneven distribution of strain on muscles and tendons that may affect the entire leg and hip. Currently available devices to treat such deformities tend to be cumbersome, inconvenient, and uncomfortable. Users may thus be unwilling to use such devices consistently, rendering them largely ineffective. The present disclosure addresses these and other issues.
As used herein, the term “toes” refers to the metatarsals and/or phalanges of a user's foot. The term “insole” refers to a removable inner sole of a shoe.

The insole 36 may be configured to position the toes 32 of a user within the interior 16 of the shoe 12 as needed to relieve and/or treat common foot and toe deformities, such as hallux valgus or overlapping toes. The shoe insole 36 may include a resilient cushion material including, for example, latex foam rubber, silicone, and/or a polymer material such as polyurethane (“PU”) or ethylene-vinyl acetate copolymer (“EVA”). In some embodiments, the insole 36 may include any combination of ridges, recesses, grooves, bumps, and/or any other suitable textures or features to improve user comfort, fit, breathability, aesthetics, or the like.
In some embodiments, the insole 36 includes a top surface 68, a bottom surface 70, and a toe area 72 to receive the user's toes 32. Multiple resilient toe separator elements 76a-76d may project from the top surface 68 of the insole 36. Each of the resilient toe separator elements 76a-76d may be separated from each other of the resilient toe separator elements 76a-76d in an arc 82 or staggered configuration. Each of the resilient toe separator element 76a-76d may be configured to be disposed between adjacent toes 32 of the user. In some embodiments, each of the resilient toe separator elements 76a-76d includes a dome-shape having a height 88 between the top surface 68 of the insole 36 and an upper surface 77 of the resilient toe separator element 76a-76d. In some embodiments, the height 88 may be in a range between about 1.0 cm and about 2.6 cm.
In some embodiments, the top surface 77 of one or more of the resilient toe separator elements 76a-76d includes an oval or other suitable oblong shape. In certain embodiments, the shape of the resilient toe separator elements 76a-76d may include curved edges to promote user comfort between adjacent toes 32. In some embodiments, one or more of the resilient toe separator elements 76a-76d extends along an axis 86 substantially parallel to the longitudinal axis 14.
In some embodiments, the resilient toe separator elements 76a-76d are monolithically formed as a single unit. In other embodiments, each of the resilient toe separator elements 76a-76d is individually molded. In some embodiments, the multiple resilient toe separator elements 76a-76d are integrated with the insole 36 such that the multiple resilient toe separator elements 76a-76d and the insole 36 are monolithically formed as a single unit. In other embodiments, the multiple resilient toe separator elements 76a-76d are coupled to the toe area 72 of the insole 36 individually or as a unit such that the each of the multiple resilient toe separator elements 76a-76d projects from the top surface 68.
The toe area 72 may span a width 74 sufficient to enable the multiple resilient toe separator elements 76a-76d to position a user's toes 32 where they should naturally fall with respect to the top surface 68. In some embodiments, the width 74 may range between about 5 cm and about 13 cm. In some embodiments, the multiple resilient toe separator elements 76a-76d are oriented along an arc 82 such that each of the multiple resilient toe separator elements 76a-76d substantially aligns with a desired orientation of a space between adjacent ones of the user's toes 32.
In some embodiments, each of the resilient toe separator elements 76a-76d includes a width 78 configured to separate adjacent ones of the user's toes 32 by a predetermined distance 80, thereby positioning the user's toes 32 where they should naturally fall. For example, in some embodiments, the width 78 may range between about 7 mm and about 20 mm to achieve a predetermined distance 80 of approximately an equivalent distance between adjacent ones of the user's toes 32. In this manner, the multiple resilient toe separator elements 76a-76d may thereby relieve and/or treat a foot or toe malady such as hallux valgus and/or overlapping toes resulting from long-term wearing of improperly-fitting shoes.
In some embodiments, the insole 36 includes a predetermined space 84 between adjacent resilient toe separator elements 76a, 76b such that the predetermined space 84 is configured to accommodate a specific one of the user's toes 32. For example, in certain embodiments, the predetermined space 84 is between about 1.0 cm and about 1.8 cm. In some embodiments, the predetermined space 84 may be greater than the width 78 of a resilient toe separator element 76a-76d. In these and other embodiments, the predetermined space 84 may be less than or equal to the height 88 of a resilient toe separator element 76a-76d.
In some embodiments, the bottom surface 70 of the insole 36 may be completely flat such that the heel 106 provides zero-drop, or no height difference, between the toe area 72 and the heel 106. In other words, the top surface 68 of the heel 106 of the insole 36 may have the same elevation as the top surface 68 of the toe area 72 of the insole 36, thereby facilitating alignment of the user's spine and a natural heel strike.

In some embodiments, the shoe 12 includes an interior 16, an exterior upper 18, and a foot opening 20. The exterior upper 18 may include canvas, leather, nylon, mesh, rubber, foam, and/or any other suitable material. The exterior upper 18 may include any suitable coating, varnish, texture, and/or protectant. In some embodiments, the exterior upper 18 includes a perimeter edge 24 defining an elongate opening 30 extending between the toe box 22 and the foot opening 20.
In some embodiments, the perimeter edge 24 includes opposing lateral edges 26a, 26b disposed substantially parallel to the longitudinal axis 14 and terminating adjacent to the toe box 22. In some embodiments, the perimeter edge 24 extends substantially perpendicularly from each of the lateral edges 26a, 26b to form a connecting edge 27. The lateral edges 26a, 26b and/or the connecting edge 27 may be substantially straight, curved, scalloped, angled, and/or a combination thereof. The opposing lateral edges 26a, 26b may be separated by a space or distance 28 equal to a width of the elongate opening 30.
In some embodiments, the shoe 12 includes a wide toe box 22. In some embodiments, the toe box 22 includes a width 74 between about 5 cm and about 13 cm. In some embodiments, the width 74 of the toe box 22 substantially corresponds to a toe area 72 of the insole 36. Thus, when the insole 36 is disposed within the interior 16 of the shoe 12, the toe area 72 and/or the resilient toe separator elements 76a-76d may be positioned within the toe box 22 and visible through the elongate opening 30.
The shoe insole 36 may include a resilient cushion material including, for example, latex foam rubber, silicone, and/or a polymer material such as polyurethane (“PU”) or ethylene-vinyl acetate copolymer (“EVA”). In some embodiments, the insole 36 may include any combination of ridges, recesses, grooves, bumps, and/or any other suitable textures or features to improve user comfort, fit, breathability, aesthetics, and/or the like.
In some embodiments, the orthotic positioning system 50 includes more than one insole 36 configured to be disposed successively, one at a time, within the interior 16 of a shoe 12 as the user becomes accustomed to the resilient toe separator elements 76a-76d and a wider foot spread. In some embodiments, each insole 36 may include progressively wider resilient toe separator elements 76a-76d configured to spread adjacent toes progressively further apart. In other embodiments, the orthotic positioning system 50 includes a single insole 36 having more than one set 75a, 75b of resilient toe separator elements 76a-76d. Each set 75a, 75b may include progressively wider resilient toe separator elements 76a-76d, thereby creating progressively greater distances 80 between corresponding adjacent toes.
In one embodiment, the orthotic positioning system 50 includes a first stage insole 38 and a second stage insole 54. Referring now to
The first stage insole 38 may include a first top surface 40, a first bottom surface 42, a first toe area 44, and first resilient toe separator elements 46a-46d projecting upwardly from the first top surface 40 along a first arc 52. When the first stage insole 38 is disposed within the interior 16 of the shoe 12, the first resilient toe separator elements 46a-46d may be positioned within the toe box 22. Each of the first resilient toe separator elements 46a-46d may include a first width 53 configured to separate adjacent ones of the user's toes 32 by a first predetermined distance 80a.
The second stage insole 54 may be configured to selectively replace the first stage insole 38 after the user has become accustomed to the first predetermined distance 80a imposed by the first stage insole 38. The second stage insole 54 may include multiple second resilient toe separator elements 62a-62d having an increased predetermined space 64 disposed therebetween. In this manner, the user may achieve an increased distance between adjacent toes 32 while limiting associated user discomfort.
Like the first stage insole 38, the second stage insole 54 may include a second top surface 56, a second bottom surface 58, a second toe area 60 configured to receive the user's toes 32, and second resilient toe separator elements 62a-62d projecting upwardly from the second top surface 56 along a second arc 66. In certain embodiments, the shape of the second resilient toe separator elements 62a-62d is substantially identical to the shape of the first resilient toe separator elements 46a-46d. Similarly, the shape of the second arc 66 may be substantially identical to the shape of the first arc 52. When the second stage insole 54 is disposed within the interior 16 of the shoe 12, the second toe area 60 and second resilient toe separator elements 62a-62d may be positioned within the toe box 22 of the shoe 12.
In some embodiments, each of the second resilient toe separator elements 62a-62d includes a second width 67 that is greater than the first width 53. The second width 67 may be greater than the first width 53 and may be configured to separate adjacent toes 32 of the user by a second predetermined distance 80b which is greater than the first predetermined distance 80a.
In other embodiments, the first resilient toe separator elements 46a-46d may be replaceable by the second resilient toe separator elements 62a-62d independently of the first stage insole 38 and the second stage insole 54. Thus, in some embodiments, a single insole 36 may configured to successively receive and support each of the first resilient toe separator elements 46a-46d and the second resilient toe separator elements 62a-62d.

In one embodiment, the resilient toe separator elements 76a-76d are molded, welded, or otherwise coupled to the top side 89 of the connector strip 90. The toe area 72 of the insole 36 may include a recess 92 disposed in its bottom surface 70. The recess 92 may include a size and shape substantially corresponding to the size and shape of the connector strip 90.
In some embodiments, the insole 36 may include multiple apertures 93 extending between the top surface 68 and the bottom surface 70. In one embodiment the apertures 93 are disposed in the recess 92. Each of the apertures 93 may have a size and a shape sufficient to accommodate one of the resilient toe separator elements 76a-76d. Further, the apertures 93 may be oriented to correspond to a position of the resilient toe separator elements 76a-76d protruding from the connector strip 90. Thus, in some embodiments, the connector strip 90 is connected to the insole 36 by inserting the resilient toe separator elements 76a-76d through corresponding apertures 93 and mounting the connector strip 90 within the recess 92. In some embodiments, the connector strip 90 may be further coupled to the recess 92 via an adhesive and/or other suitable fastening mechanism.
In some embodiments, the top surface 89 of the connector strip 90 is disposed adjacent to the bottom surface 70 of the insole 36 within the recess 92 such that the resilient toe separator elements 76a-76d project upwardly through the corresponding apertures 93 and the top surface 68 of the insole 36. In this manner, the bottom side 91 of the connector strip 90 may be substantially flush with the bottom surface 70 of the insole 36. In certain embodiments, the connector strip 90 is substantially rigid to provide support and stability to the resilient toe separator elements 76a-76d.
In some embodiments, the dimensions of each aperture 93 may be at least slightly greater than the greatest desired width 78 of a corresponding resilient toe separator element 76a-76d. In other embodiments, the recess 92 and/or portion of the insole 36 surrounding each aperture 93 may include a substantially flexible or elastic material configured to conform to the dimensions of the corresponding resilient toe separator element 76a-76d.

In some embodiments, as shown in
In some embodiments, the top edge 96 is fixably, pivotally, and/or removably coupled to the toe box 22 and/or to the connecting edge 27 via stitching, a hinge, a rivet, a grommet, a snap, a button, a zipper, a press fit, and/or any other suitable mechanical connection. Similarly, in some embodiments, the side edge 104a, 104b is fixably, pivotally, and/or removably coupled to the corresponding lateral edge 26a, 26b of the exterior upper 18 or lateral edge 29a, 29b of the sole 19 via stitching, a hinge, a rivet, a grommet, a snap, a button, a zipper, a press fit, and/or any other suitable mechanical connection.
In some embodiments, the cover 94 is configured to selectively pivot upwardly or laterally between a closed configuration 102 and an open configuration 100. The open configuration 100 may expose the elongate opening 30, thereby revealing the resilient toe separator elements 76a-76d within the toe box 22. This feature thus facilitates proper placement of the foot and positioning of the toes with respect to the resilient toe separator elements 76a-76d inside the shoe 12.
Referring now to
In some embodiments, one or more of the resilient toe separator elements 76a-76d is removably coupled to the sole 19 or insole 36 to permit the user to selectively replace and/or reposition one or more of the resilient toe separator elements 76a-76d. In these and other embodiments, the user may replace one or an entire set 75a, 75b of resilient toe separator elements 76a-76d with another one or entire set 75a, 75b of resilient toe separator elements 76a-76d having identical or varying dimensions, placement, and/or orientation.

In one embodiment, the stabilization element 34 includes one or more elongate strips of a resilient fabric or elastic. In some embodiments, the orthotic positioning apparatus 10 includes a mechanical tightening device mechanism such as a buckle, a snap, a button, a tie, or any other device or mechanism to engage the stabilization element 34 and selectively fix its position relative to the shoe 12. For example, in some embodiments, the stabilization element 34 may be selectively shortened to thereby reduce a circumference of the foot opening 20 and/or to reduce a distance 28 between the lateral edges 26a, 26b.
In some embodiments, the stabilization element 34 obstructs at least a portion of the elongate opening 30 to stabilize the shoe 12 with respect to a foot of the user. In certain embodiments, the stabilization element 34 may be adjustable and/or removable to minimize interference with visibility of the resilient toe separator elements 76a-76d disposed within the shoe 12.
