Shoe with contoured sole
First Claim
1. A shoe sole construction for a shoe, such as a street or athletic shoe, comprising:
- a sole having a sole portion and a contoured side portion;
said sole portion including a substantially flat foot support surface and defined by a substantially constant frontal plane thickness;
said side portion being defined at least in part by a frontal plane arc of a substantially circular surface having a radius equal to the thickness of said sole portion and having the center of said radius lying at a point on a plane defined by an upper surface of said sole;
said thickness of said sole portion varying in a sagittal plane and being greater in the heel area than in the forefoot area;
said radius defining the arc of said side portion correspondingly varying directly and equally with the thickness of said sole portion; and
said contoured side portion extending along at least a lateral or medial heel portion of said sole portion.

Abstract
A construction for a shoe, particularly an athletic shoe such as a running shoe, includes a sole having a load-bearing sole portion and a contoured edge stability portion. The edge portion of the sole is contoured and defined by an arc of a circle having a radius equal to the thickness of the sole portion of the sole and its center at a point lying on the plane of the upper surface of the sole thickness. However, the contour varies as the thickness of the sole portion varies due to heel lift, for example. Thus, the outer contour of the edge portion of the sole has at least a portion which lies along a theoretically ideal stability plane for providing natural stability and efficient motion of the shoe and foot in an inverted and everted mode.

33. A shoe, such as a street or athletic shoe, comprising:
-
an upper; and a sole secured to said upper and having a contoured side along at least a lateral or medial heel portion of said sole, said contoured side defined in about frontal plane cross sections at least in part by a portion of a substantially circular arc having a radius equal to a thickness of said sole and having a center of said radius at a point on about a plane defined by an upper surface of said sole, said sole thickness being greater in the heel than in the forefoot. - View Dependent Claims (34, 35, 36, 37)

- 38. A shoe sole with a sole side along at least a portion of said sole, said sole side defined at least in part by at least a portion of a quadrant with a radius substantially equaling the thickness of said sole at about an outer edge, exclusive of said side, with an inner edge of said quadrant lying perpendicular to an upper surface of said sole and an outer edge of said quadrant coinciding with said upper sole surface.
