DETAIL DESCRIPTION
[0025] Therapeutic shoes are provided that may include a left shoe and/or a right shoe having at least one laterally extending stabilizer member (e.g., an outrigger). A therapeutic shoe may be configured to provide a level stability (e.g., level 1 stability, level 2 stability, level 3 stability, etc.) for a particular shoe wearer. Stability level 1 may be, for example, associated with providing stability with no removable stabilizing members attached to an associated therapeutic shoe. Stability level 2 may be, for example, associated with providing stability with at least one relatively short removable stabilizing members (e.g., at least one 0.25 inches to 1.0 inch stabilizing member) attached to an associated therapeutic shoe. Stability level 3 may be, for example, associated with providing stability with at least one relatively long removable stabilizing member (e.g., at least one 1.0 inch to 2.0 inches stabilizing member) attached to an associated therapeutic shoe.
[0026] A therapeutic shoe configured with level on stability, for example, may be delivered to a respective shoe wearer along with a plurality of stabilizing members. The level one stability therapeutic shoe may be modified (e.g., by the shoe wearer, by a podiatrist, etc.) using at least one stabilizing member to result in a therapeutic shoe configured with level two or level three stability.
[0027] Alternatively, or additionally, a pair of therapeutic shoes may include at least one shoe having at least one sensor and at least one stabilizing member having at least one actuator. The at least one therapeutic shoe may include a stability controller configured to dynamically adjust at least one stabilizing member via, for example, the at least one actuator based on an output from the at least one sensor.
[0028] Any given therapeutic shoe may be configured, at least in part, based on input provided by a pedorthist and/or a podiatrist. For example, a pedograph may be generated for a particular shoe wearer. The systems and methods of the present disclosure may perform analysis of a footprint generated by a device used to obtain footprints for analysis. Similarly, an instrument to record and study a gait of a shoe wearer.

[0033] A therapeutic shoe in accordance with the present disclosure may be particularly designed for association with any conventional therapeutic shoe 100a-d, 10. A stabilization means may comprise at least one support which is to be associated adjacent to an inner or outer edge of a therapeutic shoe 100a-d, 10. Accordingly, the support is associated with the therapeutic shoe 100a-d, 10 relative to the intended direction of movement of the wearer of the shoe 100a-d, 10.
[0034] The support means may include an integral member which may, for example, include a triangularly shaped portion and which may define a ground engaging face and a shoe 100a-d, 10 engaging face. The cross section of the member may be such that a thicker portion of the triangle will be located near the edge of the shoe 100a-d, 10 while a thinner portion may be located inwardly thereof. Accordingly, the support member may provide for an inward or outward tilt of the shoe 100a-d, 10.
[0035] The support may be configured to be removed from the therapeutic shoe 100a-d, 10. On the other hand, a fastener may be provided for holding the support securely in place when a user walks. Accordingly, an individual employing the means of this invention can place a support on a shoe 100a-d, 10 when preparing to walk and can then quickly remove the support while performing other tasks. If the device is used for improving a person's stability, then there may be no need to remove the support.
[0036]
[0037] The support member illustrated in
[0038] Alternatively, a channel shaped member may define an opening for receiving a stabilizing member 110a-d, 115a-d, and in-turned walls of this channel shaped member may define an opening between this member and the outer surface of the wall. The stabilizing members 110a-d, 115a-d may be, for example, adapted to be rotatably or linearly received in this opening whereby the support can easily slide into place.
[0039] A base portion of a shoe 100a-d, 10, normally integral with a sole, can serve to define the channel for the stabilizing member 110a-d, 115a-d by turning the edges inwardly to form walls corresponding to the walls.
[0040] A stabilizing member 110a-d, 115a-d may include an up-turned edge which may fit around an outer edge of the sole. Inward movement of the support member 16 is thus limited by means of this edge.

[0042] The therapeutic shoe 205b may include an insole 223b. The insole 223b may include, for example, an EVA foam sock liner. The therapeutic shoe 205b may include a midsole 222b. The midsole 222b may include at least one side and/or a heel made of EVA foam that is, for example, heavier density than the EVA foam of the insole 223b. the therapeutic shoe 205b may include a tread 221b. The tread 221b may aid in side-to-side and/or front-to-back grip stability with respect to an associated support surface. The tread 221b may include, for example, “vibram” like material. While not shown in
[0043] The therapeutic shoes shown in
[0044] One advantage of the therapeutic shoes of the present disclosure is an ability to the support a person a more proper and consistent foot orientation. With the support in place, the shoe 100a-d, 10 may be tilted inwardly, and it is believed that this tends to provide a more satisfactory weight distribution when walking. Furthermore, it has been found that a more desirable stride may result when a person employs this support. Thus, it has long been recognized that many individuals tend to sway during a walk rather than to walk in line with a more or less stationary vertical line. By providing the means of this invention, it is uncomfortable to move the hips laterally and accordingly, there may be a greater natural tendency toward proper walking. It will be understood that the shoe 100a-d, 10 may improve a walking path relative to the intended direction of a line of travel of the individual wearing the shoe 100a-d, 10.
[0045] The modification illustrated in
[0046] It will be apparent to those skilled in the art that various other means could be employed for removably attaching the stabilizing member 110a-d, 115a-d to a therapeutic shoe 100a-d, 10 in the position shown. In this connection, a bracket could be fixed to the shoe 100a-d, 10 in the desired position and prongs or other extending means associated with the support could fit into this bracket. Thus, a function similar to that referred to with respect to the modification of

[0049] In normal movement of the foot during activities, such as athletic activities, the outrigger ay periodically contact the floor, ground, or other surface that sole 12 of the shoe contacts during use, but would not interfere with the user's activities. A portion of the bottom of outrigger 4 may contact the surface on which the sole rests when the shoe is being worn with the force of the weight and stance of the user determining the distribution of weight and accompanying distortion on shoe 2.
[0050] As shown in
[0051] In some embodiments, outrigger 4 may be formed integrally with the sole or a component of the sole of shoe 2, providing durability of outrigger 4. In some embodiments, an external or lower portion of outrigger 4 may be formed of the same material as the sole of shoe 2 with an additional core or filler for outrigger 4 having different elastomeric properties than the sole material. In such embodiments, the amount of lateral stiffness and comfort may be adjusted as desired. In other embodiments, outrigger may be formed integrally with another portion of the shoe above the sole, for example, in a cushion layer common to athletic shoes to which the sole material is adhered. The outrigger may molded from materials used as soles in shoes, such as plastic, rubber, rubber compounds, Vibram® or elastomer material. The outrigger may be formed entirely as a unitary member with the shoe sole, or formed as a member that is attached to the vamp or to the outer sole of the shoe. The vamp may also be formed to provide or support a portion of the outrigger.
[0052] The outrigger may extend laterally from the sole of the shoe, and is preferred to extend from the outer sole, and laterally to the side of the sole of the shoe. In some embodiments, the outrigger may not extend materially above a line defined by where the vamp meets the sole of the athletic shoe, it being recognized that athletic shoes generally have thicker soles than “street” shoes or dress shoes. In one embodiment, the outrigger may maintain a low profile, rising below the vamp of the shoe as the position of the talus within the shoe.
[0053] In some embodiments, outrigger 4 may be mounted along a lesser length of the shoe, such as from the ball, or widest part of the shoe to a point before middle of the heel. Such shorter outrigger designs may provide some roll protection while allowing for greater latitude in shoe design and style. However, the reduced length of the device may in some applications provide less roll protection than the longer lengths extending substantially the entire length of the shoe.
[0054] In one exemplary embodiment, outrigger 4 (e.g., a stabilizer member) may extend from the lateral side of the sole of the shoe from between about 1 to 2 cm from a normal width extent of a comparably sized conventional shoe. Outrigger 4 may be formed such that it extends from the most outwardly extending side of the shoe, whether the most outwardly extending portion is the vamp or the quarter of the shoe. Similarly, the outrigger may have different widths or provide variable width enhancements over a traditional width in varying amounts extending along the length of the shoe. This dimension, or additional width, may be provided sufficient to prevent inversion of the ankle of the user as the foot begins to roll under the user. Additional width beyond about 2 cm may interfere with activities of the user or with those in close contact with the user, but may be appropriate depending on the activity and the level of stability desired.
[0055] In other embodiments, such as is shown in
[0056] In another embodiment, the outrigger may have an arcuate bottom surface that curves out and away from the sole of the shoe, contacting the surface near the sole but arcing upwardly and above the surface as the bottom of the outrigger extends away from the sole. In another embodiment, the entire bottom surface of the outrigger may contact the surface.
[0057] The front of the outrigger may be formed in an arcuate shape as shown in
[0058] A stabilizing member 110a-d, 115a-d, stabilizer, or outrigger may, for example, be incorporated into a slip-on member (e.g., an overshoe, a partial overshoe, etc.). Alternatively, or additionally, a stabilizing member 110a-d, 115a-d, stabilizer, or outrigger may, for example, be configured as a shoe insert. As yet another alternative, or addition, a stabilizing member 110a-d, 115a-d, stabilizer, or outrigger may, for example, include at least one adjustable strap (e.g., an ankle strap of a high-top shoe extending from a shoe sole to a shoe top, an ankle strap of a high-top shoe extending circumferentially around at least a portion of a person's ankle, a strap extending along shoe laces from a toe of the shoe to a top of the shoe, a strap incorporated into a shoe tong, etc.).
[0059] Any given stabilizing member 110a-d, 115a-d stabilizer, or outrigger may include an actuator (e.g., a pneumatic actuator, a mechanical actuator, a hydraulic actuator, an electrical actuator, etc.) that may be configured to vary a shape and/or orientation of the stabilizing member 110a-d, 115a-d, stabilizer, or outrigger. The shape and/or orientation of the stabilizing member 110a-d, 115a-d, stabilizer, or outrigger may be manually and/or automatically varied. For example, at least one sensor (e.g., a pressure sensor, a gyroscopic sensor, a level sensor, a motion sensor, strain sensor, etc.) may be incorporated within a shoe and connected to an actuator to automatically vary a shape and/or orientation of a stabilizing member 110a-d, 115a-d, stabilizer, or outrigger. Thereby, a user's stability and/or walking may be improved.
[0060] Output(s) of at least one sensor may be connected to an input(s) of a circuit (e.g., a discrete component electrical circuit, a processor, an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a logic circuit, etc.). Output(s) of the circuit may be connected to at least one actuator. The circuit may control at least one circuit output to automatically vary a shape and/or orientation of the stabilizing member 110a-d, 115a-d, stabilizer, or outrigger based on at least one circuit input. For example, an output of a sensor may indicate that a user has begun to lean in a certain direction (e.g., pressure on a sensor has increased/decreased, strain on a sensor has increased/decreased, etc.). The circuit may automatically vary a shape and/or orientation of the stabilizing member 110a-d, 115a-d to at least partially compensate (or correct) the lean of the person (i.e., the circuit may automatically vary a shape and/or orientation of the stabilizing member 110a-d, 115a-d, stabilizer, or outrigger via at least one actuator).
