Shoe sole with rounded inner and outer side surfaces
First Claim
1. A shoe sole for providing the wearer with a stable interaction with the ground, like the interaction resulting from the curved bottom surface of the wearer'"'"'s foot sole on the ground, including:
- a shoe sole underneath portion located beneath an intended wearer'"'"'s foot sole location in the shoe sole, including at least one concavely rounded portion, the concavely rounded portion having an inner concavely rounded surface near the intended wearer'"'"'s foot sole location, as viewed in a frontal plane, when the shoe sole is upright and not under a bodyweight load, and the concavity being determined with respect to the intended wearer'"'"'s foot sole location;
the concavely rounded portion also having an outer concavely rounded surface, extending through a lowermost portion of the shoe sole as viewed in a frontal plane, when the shoe sole is upright and not under a bodyweight load, and the concavity being determined with respect to the intended wearer'"'"'s foot location, the at least one concavely rounded portion of the shoe sole being oriented around at least one of the following parts of said wearer'"'"'s foot;
a head of a first distal phalange, a head of a first metatarsal, a head of a fifth metatarsal, a base of a fifth metatarsal, a lateral tuberosity of a calcaneus, a base of a calcaneus, and a main longitudinal arch; and
a shoe sole thickness that is greater in a heel area than a forefoot area.

Abstract
A construction for a shoe, particularly an athletic shoe such as a running shoe, includes a sole that conforms to the natural shape of the foot, particularly the sides, and that has a constant thickness in frontal plane cross sections. The thickness of the shoe sole side contour equals and therefore varies exactly as the thickness of the load-bearing 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 particularly in an inverted and everted mode.
