The disclosure relates generally to a strap to be worn on a foot, and more particularly, to a strap, which can be utilized to improve running form, as a recovery aid, and/or the like.
Many athletic sport shoes made for a sport that involves running have cushioned and slightly elevated heels. This shoe configuration makes it easy for the user to “heel strike,” when running. This benefit is intentional, allowing the shoe's technology to do the work of running for the user. As shown in
When running without shoes, as shown in
Aspects of the invention provide a foot positioning device, which includes a strap, with or without an article of footwear (e.g., a sock), which can be utilized to place the foot in a desired position. For example, the strap can be configured to place the foot in a position that facilitates running with a midfoot strike. The strap also can be placed on the foot in a position to aid a user with an injury to the foot.
A first aspect of the invention provides a strap comprising: a first portion configured for placement along a forward portion of a foot; and second and third portions adjacent to opposing sides of the first portion and laterally offset from the first portion.

A third aspect of the invention provides a foot positioning device comprising: a sock; and a strap attached to the sock, the strap including: a first portion; second and third portions adjacent to opposing sides of the first portion and laterally offset from the first portion by an offset distance; and means for temporarily securing a first end of the strap to a second end of the strap.
The illustrative aspects of the invention are designed to solve one or more of the problems herein described and/or one or more other problems not discussed.
These and other features of the disclosure will be more readily understood from the following detailed description of the various aspects of the invention taken in conjunction with the accompanying drawings that depict various aspects of the invention.
It is noted that the drawings may not be to scale. The drawings are intended to depict only typical aspects of the invention, and therefore should not be considered as limiting the scope of the invention. In the drawings, like numbering represents like elements between the drawings.
As indicated above, aspects of the invention provide a foot positioning device, which includes a strap, with or without an article of footwear (e.g., a sock), which can be utilized to place the foot in a desired position. For example, the strap can be configured to place the foot in a position that facilitates running with a midfoot strike. The strap also can be placed on the foot in a position to aid a user with an injury to the foot.
As used herein, unless otherwise noted, the term “set” means one or more (i.e., at least one) and the phrase “any solution” means any now known or later developed solution. As also used herein, the term “approximately” means within +/− twenty percent.
Turning to the drawings,
However, it is understood that use of hook and loop fasteners is only illustrative, and the mechanisms 12A, 12B can implement any solution for temporarily securing the opposing ends of the strap 10. Furthermore, it is understood that while mechanisms 12A, 12B are shown located on opposing sides of both ends of the strap 10, it is understood that, depending on the securing solution utilized, the strap 10 can include mechanisms 12A, 12B located on the same side of the opposing ends, or only a mechanism located on only one end of the strap 10. To this extent, in other embodiments, the opposing ends of the strap 10 can be secured through one or more of: clips, reusable adhesive, a self-adhering property of material(s) located on the opposing ends of the strap 10, and/or the like. In still another embodiment, an embodiment of the strap 10 can comprise a loop, with no opposing ends. In this case, the strap 10 can include a mechanism for temporarily adjusting a size of the loop to accommodate feet of varying sizes.
As discussed herein, the strap 10 can be sized and configured to be wrapped around a foot of a user. To this extent, the strap 10 is shown including an offset portion 14, which is defined by a pair of transition regions 16A, 16B. As illustrated, the offset portion 14 is not aligned with the remainder of the strap 10. In an embodiment, the offset portion 14 is centrally located on the strap 10. However, it is understood that the offset portion 14 can be located anywhere along a length of the strap 10. In an embodiment, a length, Lop, of the offset portion 14 (e.g., as defined by the distance between the transition regions 16A, 16B) is selected to be approximately the same as a widest part of a foot of a target user (e.g., the forward portion of the foot, just below the metatarsals). In an embodiment, the offset portion 14 is offset from the remainder of the length of the strap 10 by an amount, Doffset, that is approximately the same as a height of the foot of the target user at the widest part of the foot. Each transition region 16A, 16B can have a length approximately twice that of the distance that the offset portion 14 is offset from the remainder of the strap 10. In a more particular embodiment, the strap 10 has a total length of approximately twenty inches (51 centimeters); the offset portion 14 of the strap 10 has a length of approximately four inches (10 centimeters) and is vertically offset from the remainder of the strap 10 by approximately 0.75 inches (2 centimeters); and each of the transition regions 16A, 16B has a length of approximately 1.5 inches (4 centimeters).
The strap 10 can be formed of any material having a sufficient strength and durability to hold the foot in a desired position during use of the strap 10. In an embodiment, the strap 10 is formed of a single, continuous strip of a rubber latex material, which has a thickness of approximately 0.04 inches (0.1 centimeters) and a width of approximately 1.5 inches (4 centimeters). However, it is understood that this is only illustrative and any comparable materials and configurations providing approximately the same strength or greater can be utilized. For example, in another embodiment, the strap 10 can be fabricated of a thin neoprene backed with polyester on one side and unbroken loop fabric on the other side or another type of synthetic rubber, having similar dimensions as described herein. Regardless, it is understood that any material having properties (e.g., strength, flexibility) similar to the materials described herein can be utilized. Furthermore, it is understood that the offset portion 14 can have a width that differs from the width of the remainder of the strap 10. Additionally, the offset portion 14 and/or the transition regions 16A, 16B can be formed of a distinct material from the end portions of the strap 10. For example, the offset portion 14 can be formed of a material having less elasticity than the end portions of the strap 10. In an embodiment, the material(s) and/or dimensions of the strap 10 are selected to allow the user to comfortably wear one or more articles of footwear, such as shoes and/or socks, over the strap 10 when it is placed on the foot while providing sufficient strength and elasticity for the desired application.
In an embodiment, the strap 10 can be placed on a foot to hold the foot in an optimal position for a midfoot/forefoot strike during running/sprinting. To this extent,
While the strap 10 shown being secured behind the ankle, it is understood that embodiments of the strap 10 can be configured to be secured anywhere on the user's foot. For example, an embodiment of the strap 10 can be configured to be secured on an interior or exterior portion of an ankle of the user. In this case, the offset portion 14 of the strap 10 can be located more closely to one end of the strap 10 than the other. In a more specific embodiment, for a strap 10 having a total length of approximately twenty inches (51 centimeters), an offset portion 14 of the strap 10 having a length of approximately four inches (10 centimeters), and each of the transition regions 16A, 16B having a length of approximately 1.5 inches (4 centimeters). One end portion of the strap 10 can have a length of approximately 8 inches (20 centimeters) and the other end portion of the strap 10 can have a length of approximately 5 inches (13 centimeters).
In this position, the force of the strap 10 effectively bends the foot, thereby placing the foot in a slight plantar flexion. As a result, the strap 10 holds the foot in a position conducive for a mid-foot/forefoot strike. When the user is running, the mid-foot/forefoot strike will naturally be made, even when the user is wearing athletic shoes. The strap 10 can be configured to provide a slight plantar flexion, which is within the normal range of motion for the user. As a result, the strap 10 will not add strain on the foot. Rather, the strap 10 can place sufficient force on the foot so that the plantar fascia and calf muscles are engaged in active flexion.
In another embodiment, the strap 10 can be placed on a foot to provide a recovery and/or sleeping aid. For example, the strap 10 can be used by an individual dealing with a training-related injury, such as plantar fasciitis, shin splints, tendonitis, and/or the like. Furthermore, the strap 10 can be used to assist in managing muscle tightness in the arch and/or lower leg of a user. To this extent,
As described herein, a position of the strap 10 on the foot can be important to provide the desired force, e.g., when worn during running as described herein. In an embodiment, an article of footwear, such as a sock, is configured to assist the user with the correct placement. For example, the sock can include a design element, which identifies the proper location to place the offset portion 14 of the strap 10.
In an embodiment, an article of footwear, such as a sock, is configured to hold the strap 10 in a desired position. For example,
While embodiments described herein use a sock as an illustrative footwear article, it is understood that a strap described herein can be implemented in conjunction with any suitable footwear article. For example, an illustrative footwear article can comprise a shoe, such as a running shoe. More particularly, the running shoe can have minimal cushioning (e.g., racing flats). Furthermore, it is understood that the sock can comprise any type of sock. In a more specific embodiment, the sock is a compression sock, which can be configured to increase circulation in the foot.
While illustrative aspects of the invention have been shown and described herein primarily in conjunction with a foot positioning device, it is understood that aspects of the invention further provide various alternative embodiments.
For example, an embodiment provides a method of holding a foot in a desired position. In this case, a foot positioning device can be placed on the foot in a manner described herein. For example, a strap of the foot positioning device can be placed on the foot as shown in
The foregoing description of various aspects of the invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed, and obviously, many modifications and variations are possible. Such modifications and variations that may be apparent to an individual in the art are included within the scope of the invention as defined by the accompanying claims.
The current application is a continuation of U.S. patent application Ser. No. 15/213,949, filed on 19 Jul. 2016, and which claims the benefit of U.S. Provisional Application No. 62/198,660, filed on 29 Jul. 2015, each of which is hereby incorporated by reference.
