Foot orthotic
A foot orthotic comprising: a toe platform, the toe platform comprising a toe, sulcus, and ball; a longitudinal arch pad in communication with the toe platform; a heel cup in communication with the longitudinal arch pad, the heel cup comprising a heel; where the orthotic is made from a flexible material, and where in order to form an angle β that is greater than 0° between the toe platform and the remainder of the orthotic, a pre-load pressure P is required.
1. A foot orthotic, comprising:
a flexible element consisting of a sheet of material of substantially uniform thickness, the sheet of material defining a toe region, a heel region and a longitudinal arch pad region that extends from the toe region to the heel region, the sheet of material being structurally formed such that (i) only the toe region and the heel region contact a ground surface plane, and (ii) the longitudinal arch pad is spaced above the ground surface plane;
wherein the flexible element is fabricated from a flexible material that includes pre-impregnated carbon fibers; and wherein the pre-impregnated fibers are unidirectionally aligned.
2. The foot orthotic of claim 1 , wherein the substantially uniform thickness of the sheet of material includes thicknesses that vary by about 0.5 mm.
3. The foot orthotic of claim 1 , wherein the sheet of material further defines a ball region spaced from the toe region and wherein the sheet of material is structurally formed such that the ball region is spaced above the ground surface plane.
4. The foot orthotic of claim 1 , wherein the flexible element defines a big toe region in a medial plantar portion of the toe region, and wherein the big toe region defines a non-zero angle dip relative to a lateral plantar portion of the toe region.
5. The foot orthotic of claim 4 , wherein the non-zero angle is about 1° to about 25°.
6. The foot orthotic of claim 1 , wherein the thickness of the flexible element in the toe platform region is about 1 mm to about 1.75 mm, wherein the thickness of the flexible element in the longitudinal arch pad region is about 1.25 mm to about 2 mm, and wherein the thickness of the flexible element in the heel region is about 1.5 mm to about 2.25 mm.
7. A foot orthotic, comprising:
a flexible element consisting of a sheet of material of substantially uniform thickness, the sheet of material defining a toe region, a heel region and a longitudinal arch pad region that extends from the toe region to the heel region, the sheet of material being structurally formed such that (i) only the toe region and the heel region contact a ground surface plane, and (ii) the longitudinal arch pad is spaced above the ground surface plane;
wherein the flexible element is fabricated from a flexible material that includes pre-impregnated carbon fibers; and
wherein the pre-impregnated carbon fibers are incorporated into a woven cloth.
8. The foot orthotic of claim 7 , wherein the thickness of the flexible element in the toe platform region is about 1 mm to about 1.75 mm, wherein the thickness of the flexible element in the longitudinal arch pad region is about 1.25 mm to about 2 mm, and wherein the thickness of the flexible element in the heel region is about 1.5 mm to about 2.25 mm.
9. The foot orthotic of claim 7 , wherein the flexible element defines a big toe region in a medial plantar portion of the toe region, and wherein the big toe region defines a non-zero angle dip relative to a lateral plantar portion of the toe region.
10. The foot orthotic of claim 9 , wherein the non-zero angle is about 1° to about 25°.
11. A foot orthotic, comprising:
a flexible element consisting of a sheet of material of substantially uniform thickness, the sheet of material defining a toe region, a heel region and a longitudinal arch pad region that extends from the toe region to the heel region, the sheet of material being structurally formed such that (i) only the toe region and the heel region contact a ground surface plane, and (ii) the longitudinal arch pad is spaced above the ground surface plane;
wherein the flexible element defines a big toe region in a medial plantar portion of the toe region, and wherein the big toe region defines a non-zero angle dip relative to a lateral plantar portion of the toe region.
12. The foot orthotic of claim 11 , wherein the thickness of the flexible element in the toe platform region is about 1 mm to about 1.75 mm, wherein the thickness of the flexible element in the longitudinal arch pad region is about 1.25 mm to about 2 mm, and wherein the thickness of the flexible element in the heel region is about 1.5 mm to about 2.25 mm.
13. The foot orthotic of claim 11 , wherein the flexible element is fabricated from a flexible material that includes pre-impregnated carbon fibers.
14. The foot orthotic of claim 11 , wherein the flexible element is fabricated from a flexible material that includes several layers of cured pre-impregnated carbon fiber fabric.
15. The foot orthotic of claim 13 , wherein the pre-impregnated carbon fibers are incorporated into a woven cloth.
16. The foot orthotic of claim 13 , wherein the flexible element includes pre-impregnated fibers that are unidirectionally aligned.
