Abstract
Abstract An orthopedic canvas shoe containing a supporting arch and having a continuous flexible sole wherein the sole is formed such that the inside heel and arch portions of the sole are slightly elevated with respect to the remainder of the sole. The arch of the shoe is positioned such that the highest portion of the arch fits directly beneath the navicular bone of the foot. The arch is further supported and the foot held in proper position by extending the sole forwardly from the heel to the widest portion of the shoe supporting the ball of the foot in a straight line. Orthopedic soles having the same medial heel and arch elevations and having a filled in arch portion are adapted to be adhesively connected to any conventional upper to form an orthopedic shoe and thereby provide a method to correct and/or prevent the pronation of feet.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
113 words
A flexible orthopedic sole having a medial wedge forming part of the lower surface in the heel portion thereof which gradually slopes laterally and forwardly to become integral with the normal sole surface, said sole being filled in and curving upwardly in the area of the plantar arch, terminating such that the medial side of the sole forms essentially a straight line extending from the heel of the sole to the portion of the sole adapted to accommodate the medial side of the ball of the foot, the upper surface of said sole containing a rim around the periphery thereof thereby forming an upper surface receptacle adapted to receive a shoe upper therein.
Claim 2
Dependent Claim
113 words
A flexible orthopedic sole having a medial wedge forming part of the lower surface in the heel portion thereof which gradually slopes laterally and forwardly to become integral with the normal sole surface, said sole being filled in and curving upwardly in the area of the plantar arch, terminating such that the medial side of the sole forms essentially a straight line extending from the heel of the sole to the portion of the sole adapted to accommodate the medial side of the ball of the foot, the upper surface of said sole containing a rim around the periphery thereof thereby forming an upper surface receptacle adapted to receive a shoe upper therein.
Claim 3
Dependent Claim
35 words
A flexible orthopedic sole according to claim 1 wherein the medial wedge is contiguous with the sole and is highest under the heel on the medial side and terminates just forward of the navicular bone.
Claim 4
Dependent Claim
43 words
A flexible orthopedic sole according to claim 2 wherein the medial wedge is about 1/8 of an inch thick on the medial side of the heel and gradually lessens in with, both laterally and forwardly in the plantar arch area of the sole.
Claim 5
Dependent Claim

A flexible orthopedic sole according to claim 3 wherein the filled in and upwardly curving portion in the area of the plantar arch is adapted to fit both under and alongside said arch.
Claim 6
Dependent Claim
118 words
An orthopedic shoe comprising: a flexible orthopedic sole having a medial wedge forming part of the lower surface in the heel portion thereof which gradually slopes laterally and forwardly to become integral with the normal sole surface, said sole being filled in and curving upwardly in the area of the plantar arch, terminating such that the medial side of the sole forms essentially a straight line extending from the heel of the sole to the portion of the sole adapted to accommodate the medial side of the ball of the foot, the upper surface of said sole containing a rim around the periphery thereof thereby forming an upper surface receptacle into which is adhesively secured a shoe upper.
