Description

BRIEF DESCRIPTION OF THE FIGURES

[0024] The accompanying drawings illustrate several embodiments and, together with the description, serve to explain the principles of the invention according to the embodiments. It will be appreciated by one skilled in the art that the particular arrangements illustrated in the drawings are merely exemplary and are not to be considered as limiting of the scope of the invention or the claims herein in any way.

[0025] FIGS. 1-6 illustrate an embodiment of the inventive apparatus of the present invention in accordance with an embodiment of the invention.

[0026] FIGS. 7A-7D illustrate one or more embodiments of the inventive apparatus in various views.

DETAILED DESCRIPTION

[0027] FIGS. 1, 2 and 3 illustrate various elements of the contoured insole apparatus in accordance with one exemplary embodiment of the invention. The elements of the contoured insole apparatus include a heel cup providing a valgus tilt to the user's foot, a medial arch support member, and a midfoot lateral support member.

[0028] The apparatus as a whole supports a user's foot by minimizing pronation and heel inversion. Moreover, each element of the apparatus independently provides sufficient tilt and contour support to ensure that the user's foot pronates and/or supinates minimally. For example, the heel cup member may be contoured minimize heel inversion. The medial arch support member is contoured to minimize heel inversion and pronation. The midfoot lateral support member is similarly designed and contoured to reduce pronation and supination.

[0029] The inventive apparatus generally conforms to the user's foot and the length and size of the inventive apparatus may be determined by the user's shoe size and/or foot measurements. In one embodiment of the invention, the inventive apparatus may be manufactured in a few different sizes (such as small, medium, large, extra-large, etc,), which may fit users with a range of shoe and/or feet sizes. As such, the inventive apparatus may ensure a universal fit, which may be used by a variety of users.

[0030] The inventive apparatus may be comprised of hard, molded plastic. However, in other embodiments, it may be comprised of semi-flexible molded plastic that minimally flexes when weight is applied to it. Other possible embodiments of the composition of the inventive apparatus include a moisture absorbing covering or bacteria repelling covering. Other material may be used, as would be readily apparent to a person of ordinary skill in the art, without departing from the scope of the invention.

[0031] Although the inventive apparatus is generally described herein as an insole. It may nevertheless be a part of an article of footwear. For example, shoes, boots, sandals, etc., may be comprised of the inventive apparatus described herein without departing from the scope of the invention.

Heel Cup

[0032] FIGS. 4, 5 and 6 illustrate exemplary embodiments of the contoured insole apparatus' heel cup

[0033] In one exemplary embodiment of the invention, the heel cup applies a valgus tilt to the user's foot. The valgus tilt re-distributes the user's weight throughout the inventive apparatus. In other words, the vulgus tilt essentially prevents heel inversion. In accordance with currently available data about growing average height and weight of human users in a variety of countries and regions, it is believed that a three degree vulgus tilt would adequately addressand prevent heel inversion in most users. As such, the shape of the heel cup may provide a three-degree vulgus tilt to the user's foot. As would be readily understood by a person of ordinary skill in the art, the present invention is not limited to a three-degree vulgus tilt. Other degrees of tilt may be used, as would be readily understood by a person of ordinary skill in the art, without departing from the scope of the invention.

[0034] The heel cup may he comprised of semi-flexible molded plastic that minimally flexes and which provides a four degree valgus tilt to the user's foot. The valgus tilt, tilts the user's foot and maintains the tilt with some deviation. The heel cup may also be molded to fit within a specific size of footwear and is placed in the foot bed of the footwear. The valgus tilt, tilts the user's foot and maintains the tilt with little deviation.

[0035] In one embodiment of the invention, the heel cup is comprised of a depression. In one exemplary embodiment the depression extends three inches within the insole apparatus. This depression or heel cup cradles the user's heel in order to provide stability and minimize heel inversion.

[0036] As would be understood from the entirety of the disclosure, the invention disclosed herein is not limited to a three or four degree valgus tilt or to hard or semi-flexible plastic. It should be noted that the valgus tilt may be configured to accommodate the specific needs of a user and varying the degree of the valgus tilt will not depart from the scope of the invention.

Medial Arch Support Element

[0037] FIGS. 4 and 5 illustrate exemplary embodiments of the contoured insole apparatus's medial arch support member. In one exemplary embodiment of the invention, the contoured insole apparatus' medial arch support member may include a medial arch support that conforms to the user's foot. In one instance, the medial arch support member may he comprised of a raised portion that adequately contours to, and supports the arch on the user's foot.

[0038] The medial arch support member prevents or minimizes pronation of the user's foot. This function may be performed by preventing a user's arch from collapsing and causing pronation when adequate weight is applied to the user's foot. This minimizes pronation that may be experienced by a user's foot or leg as the user walks, runs, or otherwise moves.

[0039] The medial arch support member may be comprised of the same material as described above with respect to the heel cup. For example, the material may he comprised of hard, molded plastic which is molded in a way to cup and form to the user's foot. The medial arch support may be comprised of semi-flexible molded plastic.

[0040] The medial arch support member, as illustrated in FIGS. 4 and 5, are exemplary and the heel cup depictions are not intended to be limited to any particular depression size, length or material. It should be noted that the medial arch support member may be varied in size, shape, length, curvature, incline and composition as would be readily apparent to a person of ordinary skill in the art, without departing from the scope of the invention.

Midfoot Lateral Support

[0041] FIGS. 5 and 6 illustrate exemplary embodiments of the midfoot lateral support member. The midfoot lateral support member provides lateral support to the midfoot to minimize pronation or supination.

[0042] In another exemplary embodiment of the midfoot lateral support member provides lateral support to the midfoot to prevent the user's foot from pronating more than a few degrees in either lateral direction. This exemplary lateral support member may be comprised of semi-flexible molded plastic to minimally flex when weight is applied.

[0043] In one exemplary embodiment, the midfoot lateral support member may be comprised of hard, molded plastic ensuring that the user's foot remains in a neutral position.

[0044] The midfoot lateral support member embodiments, as illustrated in FIGS. 5 and 6, are exemplary and not intended to be limited to any particular composition or size. It should be noted that the midfoot lateral support member may be varied in shape, length, curvature, and incline as would be readily apparent to a person of ordinary skill in the art, without departing from the scope of the invention.

[0045] Additionally, the midfoot lateral support member is not limited to any particular method of midfoot lateral support. Any number of alternative ways of providing lateral support may be used as would be readily apparent to a person of ordinary skill in the art, without departing from the scope of the invention.
