Abstract
A correctional running shoe with an upper shoe attached to a negative sole having a heel, a specially designed flexible midsole, and a toe portion, all made from cushioned material. The heel has at least about 1/6 to about 1/3 less thickness than the toe portion so that the foot naturally rests with the toe inclined and the heel downward.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A correctional running shoe, designed to force a toe/heel running gait, comprising;
an upper shoe attached to a negative sole having a heel portion, a midsole portion, and a toe portion, all made from cushioned sole material; said heel portion having about ⅙ to about ⅓ less thickness than said toe portion; and said midsole portion having force deflection struts to provide a maximum flexible midsole area under the arch of a wearer's foot.
2 . The correctional running shoe of claim 1 wherein the heel portion has a thickness of about 20 mm to 30 mm.
3 . The correctional shoe of claim 1 wherein the toe portion has a thickness of about 33 mm to about 45 mm.
4 . The correctional shoe off claim 1 having a heel thickness of 20 mm to 25 mm and a toe portion thickness of 30 mm to 35 mm.
5 . The correctional shoe of claim 1 wherein the midsole has at least two struts elements oriented along a long axis of the shoe sole.
6 . The correctional shoe of claim 5 wherein the force deflection struts are selected from the group consisting of ribs of the cushioned sole material, separate embedded plate elements of a different material, impact air cushions, or embedded polymer material different than the rest of the sole.
7 . The correctional shoe of claim 6 wherein the force deflection struts are selected from the shape of struts of c-shaped, s-shaped or wavy shaped struts.
8 . A negative sole for a running shoe, comprising:
a negative sole having a heel portion, a midsole portion, and a toe portion, all made from cushioned sole material; said heel portion having about ⅙ to about ⅓ less thickness than said toe portion; and said midsole portion having force deflection struts to provide a maximum flexible midsole area under the arch of a wearer's foot.Join the waitlist — get patent alerts
