Patent ID: 8371047

Claim:
A cushioned wedged insole kit for the treatment of osteoarthritis comprising; at least one wedged slab having a wedged slab flat bottom and a wedged slab sloping top oriented in a non-parallel manner to the wedged slab flat bottom thereby defining a longitudinal upper edge along a maximum thickness of the wedged slab and a longitudinal lower edge along a minimum thickness of the wedged slab, wherein the sloping top is oriented at a first slab angle from the horizontal that is at least 2.5 degrees and no more than 10 degrees, wherein the wedged slab is formed at least in part of an elastic material that partially collapses under compressive force and rebounds when compressive force is removed; at least one neutral slab having a neutral slab flat bottom and a neutral slab flat top oriented in a substantially parallel manner to the neutral slab flat bottom, thereby defining a constant neutral slab thickness that is substantially equal to the wedged slab minimum thickness, wherein the neutral slab is formed at least in part of an elastic material that partially collapses under compressive force and rebounds when compressive force is removed; and at least one sizing chart that cooperates with the wedged slab sloping top and the neutral slab flat top to indicate the outline of at least one shoe size for at least one foot including a lateral shoe edge, wherein the sizing chart cooperates with the wedged slab so that (i) the lateral shoe edge may be in proximity to the wedged slab longitudinal upper edge to facilitate trimming of the wedged slab to create a lateral wedged insole, or (ii) the lateral shoe edge may be in proximity to the wedged slab longitudinal lower edge to facilitate trimming of the wedged slab to create a medial wedged insole.
