Medial/lateral counter foot stabilizer
First Claim
1. An orthotic stabilizer for a shoe comprising:
- a plantar aspect which extends substantially the length of the sole of a shoe;
a heel cup counter comprising a base and walls of sufficient height to support the medial and lateral sides of a heel positioned in said heel cup, and wherein said heel cup walls are each of substantially equal height and shaped to support the inner and outer heel to substantially the same extent;
a lateral side wall extending from said heel cup counter and at least a part of said plantar aspect, and wherein with respect to a foot positioned in the stabilizer, said lateral wall begins its descent from the counter at a point about midway between the fifth metatarsal head and the base of the fifth metatarsal to merge with the plantar aspect at a point just proximal to the apex of the fifth metatarsal head;
a medial wall extending from said heel cup counter and at least a part of said plantar aspect, wherein with respect to a foot positioned in the stabilizer, said medial wall begins its descent near the navicular bone and descends to merge with the plantar aspect at a point just proximal to the apex of the first metatarsal head;
and having said medial wall and said plantar aspect comprise a convex surface which at least in part comprises a medial arch support, said lateral wall and said plantar aspect comprise a convex surface which at least in part comprises a lateral arch support, and said plantar aspect comprise a convex mound which comprises a metatarsal arch support.

Abstract
The invention relates to an apparatus and methods for incorporating a medial/lateral counter foot stabilizer into shoes. In an embodiment, the medial/lateral counter foot stabilizer of the invention comprises a plantar aspect which extends the length of the sole of a foot, side walls, a metatarsal arch support, a lateral arch support, a medial arch support, and a heel cup counter. The stabilizer of the invention mimics a preferred foot shape, provides support for the metatarsal, medial, and lateral arches, and restricts pronation and supination of the foot. The stabilizer of the invention is designed to be integrated into commercial shoes during the manufacturing process as a method of providing foot support which is currently unavailable in commercial shoes.

-
a plantar aspect which extends substantially the length of the sole of a shoe;
a heel cup counter comprising a base and walls of sufficient height to support the medial and lateral sides of a heel positioned in said heel cup, and wherein said heel cup walls are each of substantially equal height and shaped to support the inner and outer heel to substantially the same extent;
a lateral side wall extending from said heel cup counter and at least a part of said plantar aspect, and wherein with respect to a foot positioned in the stabilizer, said lateral wall begins its descent from the counter at a point about midway between the fifth metatarsal head and the base of the fifth metatarsal to merge with the plantar aspect at a point just proximal to the apex of the fifth metatarsal head;
a medial wall extending from said heel cup counter and at least a part of said plantar aspect, wherein with respect to a foot positioned in the stabilizer, said medial wall begins its descent near the navicular bone and descends to merge with the plantar aspect at a point just proximal to the apex of the first metatarsal head;
and having said medial wall and said plantar aspect comprise a convex surface which at least in part comprises a medial arch support, said lateral wall and said plantar aspect comprise a convex surface which at least in part comprises a lateral arch support, and said plantar aspect comprise a convex mound which comprises a metatarsal arch support. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12)

13. A method of correcting foot and leg injury comprising integrating a lateral/medial counter stabilizer in a shoe, wherein said lateral/medial counter stabilizer comprises:
-
a plantar aspect which extends substantially the length of the sole of a shoe;
a heel cup counter comprising a base and walls of sufficient height to support the medial and lateral sides of a heel positioned in said heel cup, and wherein said heel cup walls are of substantially the same height and shaped to support the inner and outer heel to substantially the same extent;
a lateral side wall extending from said heel cup counter and at least a part of the plantar aspect, and wherein with respect to a foot positioned in the stabilizer, said lateral wall begins its descent from the counter at a point about midway between the fifth metatarsal head and the base of the fifth metatarsal to merge with the plantar aspect at a point just proximal to the apex of the fifth metatarsal head;
a medial wall extending from said heel cup counter and at least a part of the plantar aspect, wherein with respect to a foot positioned in the stabilizer, said medial wall begins its descent near the navicular bone and descends to merge with the plantar aspect at a point just proximal to the apex of the first metatarsal head;
and having said medial wall and said plantar aspect comprise a convex surface which at least in part comprises a medial arch support, said lateral wall and said plantar aspect comprise a convex surface which at least in part comprises a lateral arch support, and said plantar aspect comprise a convex mound which comprises a metatarsal arch support. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A method for reducing foot and leg injury comprising prevention of heel misalignment due to pronation or supination of the foot and providing support for the lateral, metatarsal and medial arches, comprising:
- integrating a lateral/medial counter stabilizer into a shoe, wherein said stabilizer comprises an extended plantar aspect;
lateral and medial side walls;
a heel cup counter comprising a base and walls, wherein said walls of said counter are of substantially the same height and shaped to reduce rotation of a heel positioned in said heel cup counter to less than 10 degrees during a standard gait; and
having said medial wall and said plantar aspect comprise a convex surface which at least in part comprises a medial arch support, said lateral wall and said plantar aspect comprise a convex surface which at least in part comprises a lateral arch support, and said plantar aspect comprise a convex mound which comprises a metatarsal arch support. - View Dependent Claims (26)
- integrating a lateral/medial counter stabilizer into a shoe, wherein said stabilizer comprises an extended plantar aspect;
-
27. A method for reducing foot and leg injury comprising integrating an orthotic stabilizer into a shoe, wherein said stabilizer is custom-molded to provide orthotic treatment to an individual foot, and wherein said stabilizer comprises:
-
a plantar aspect which extends substantially the length of the sole of a shoe;
a heel cup counter comprising a base and walls of sufficient height to support the medial and lateral sides of a heel positioned in said heel cup, and wherein said heel cup walls are each of substantially the same height and shaped to support the inner and outer heel to substantially the same extent;
a lateral side wall extending from said heel cup counter and at least a part of the plantar aspect, and wherein with respect to a foot positioned in the stabilizer, said lateral wall begins its descent from the counter at a point about midway between the fifth metatarsal head and the base of the fifth metatarsal to merge with the plantar aspect at a point just proximal to the apex of the fifth metatarsal head;
