[0051] Although the present invention has been illustrated and described herein with reference to preferred embodiments and specific examples thereof, it will be readily apparent to those of ordinary skill in the art that other embodiments and examples may perform similar functions and/or achieve like results. All such equivalent embodiments and examples are within the spirit and scope of the present invention, are contemplated thereby, and are intended to be covered by the following claims.
[0052] The present invention will now be described by referencing the appended figures representing preferred embodiments. FIG. 1 & FIG. 2 depicts a tightly fitted sock/stocking 1 adhered to a polymer insole 2. The insole is fitted with antipronation/supination lugs (projections) 3 on the sides (at mid-foot) that, when engaged, will resist rotation of the foot within the footwear. A mid-foot strap 4 will help to firmly position and prevent movement of the side lugs 3. Lugs are also located along the bottom of the insole that, when engaged within the footwear, will prevent the heel 8 and the forefoot 9 from sliding front to back as well as side to side. These lugs help prevent the heel latch mechanism from disengaging. A toe lug 5 will firmly position the toe within the footwear and resist rotation. A modification to the insole (recessed area in this embodiment) 10 will allow the positioning of orthotic devices, ankle wraps, orthopedics etc. without effecting the “fit” of the Outer Shoe and creating a more secure connection to the Insole Appliance. In this version of the heel locking mechanism the “strike” (receiver device) 7 will receive the latch 13—preventing the heel from rising upward when engaged. The shape of the latch/strike will also prevent the rotation of the heel relative to the outer shoe. In this embodiment, a hook and loop connector 6 may be applied to the Sock Insole Appliance to allow the Othotic Device (ankle wraps, special orthopedic devices) to be firmly connected and to form a more integral connection with the total System.
[0053] FIG. 3 & FIG. 4 depicts the Insole Appliance from FIG. 1 & FIG. 2 with an embodiment of an optional Orthotic Device (ankle wrap) 12 in place and secure to the hook and loop connector 6.
