Patent ID: 6968635

Claim:
A shoe comprising: a bottom; a major longitudinal axis; an upper including an arch region and a heel region; a sole including a rear sole, the rear sole being below at least a portion of the heel region of the upper, the rear sole including a forward portion and an opposite rearward portion, the rear sole having a bottom surface having a perimeter, the bottom surface having a ground-engaging portion, the ground-engaging portion of the bottom surface including at least one substantially planar portion having an outer edge proximate a portion of the perimeter of the bottom surface of the rear sole, the at least one substantially planar portion being located proximate at least one of a medial side of the shoe and a lateral side of the shoe, the ground-engaging portion of the bottom surface including at least one portion non-planar with the at least one substantially planar portion, the at least one non-planar portion positioned proximate the perimeter of the bottom surface and inclined upwardly in a direction toward the perimeter of the bottom surface from another portion of the bottom surface, the at least one non-planar portion having an outer edge proximate a portion of the perimeter of the bottom surface and proximate the rearward portion of the rear sole, the portion of the perimeter of the bottom surface of the rear sole to which the outer edge of the at least one substantially planar portion is proximate and the portion of the perimeter of the bottom surface of the rear sole to which the outer edge of the at least one non-planar portion is proximate each having the shape of an arc of a circle, the circle having a diameter no greater than the maximum width of the bottom surface of the rear sole as measured on a line generally perpendicular to the major longitudinal axis of the shoe from a point on the medial side of the shoe to a point on the lateral side of the shoe; a plate having an upper surface, a lower surface, an interior portion and peripheral portions and positioned between at least a portion of the outsole of the rear sole and at least a portion of the heel region of the upper, at least one of the peripheral portions of the plate being proximate at least one of the medial side of the shoe, the lateral side of the shoe and a rear of the shoe, the interior portion of the plate being positioned over a void and exposed to the void, at least a portion of the plate capable of being deflected in a direction substantially perpendicular to the major longitudinal axis of the shoe; at least one opening in the shoe, the opening being in air communication with the void to expose the interior portion of the plate from outside the shoe through the opening and the void; and an arch bridge integral with the plate extending from a position proximate a forward portion of the plate, forward beneath at least a portion of the arch region of the upper.
