Abstract:
An athletic shoe sole for a shoe, the athletic shoe sole comprising:a sole heel area of the athletic shoe sole at a location substantially corresponding to the location of a heel of an intended wearer's foot when inside the shoe; a sole forefoot area at a location substantially corresponding to the location of a forefoot of an intended wearer's foot when inside the shoe; a sole midtarsal area located between the sole heel area and the sole forefoot area; the sole heel, midtarsal, and forefoot areas each having a sole medial side, a sole lateral side, and a sole middle part located between the sole sides, as viewed in a shoe sole frontal plane during a shoe unloaded, upright condition; a sole inner surface adjacent an intended wearer's foot location inside the shoe having at least a first concavely rounded portion, said concavity being determined relative to an intended wearer's foot location inside the shoe, as viewed in a frontal plane located in the sole forefoot area, during an unloaded, upright shoe condition; the sole lateral side including a sidemost lateral section at a location outside of a straight vertical line extending through the sole lateral side at the sidemost extent of the sole inner surface of the sole lateral side, as viewed in a shoe sole frontal plane during an unloaded, upright shoe condition; the sole medial side including a sidemost medial section at a location outside of a straight vertical line extending through the sole medial side at the sidemost extent of the sole inner surface of the sole medial side, as viewed in a shoe sole frontal plane during an unloaded, upright shoe condition; a sole outer surface extending from the sole inner surface and defining the outer boundary of each shoe sole side, as viewed in a frontal plane; a second concavely rounded portion forming a part of the sole outer surface of the sole side that extends through a lowermost portion of the sole outer surface of one of the lateral and medial sole sides, the concavity being determined relative to an intended wearer's foot location inside the shoe, as viewed in the frontal plane during an unloaded, upright shoe condition; the sole forefoot area including the following combined components: a forefoot lift, a midsole component and an outsole component, the inner and outer boundaries of the combined components being formed by said sole inner and outer surfaces, as viewed in a shoe sole frontal plane in the sole forefoot area, during an unloaded, upright shoe condition; the sole forefoot area of the shoe sole having a greater thickness than the sole heel area, as viewed in a sagittal plane during an unloaded, upright shoe condition; the thickness of the shoe sole being defined as the distance between the sole inner surface and the sole outer surface, as viewed in the sagittal plane during an unloaded, upright shoe condition; at least one of said combined components extending into the sidemost section of at least the sole side of the sole forefoot area having the concavely rounded inner and outer surface portions, as viewed in a shoe sole frontal plane during an unloaded, upright shoe condition, and at least an upper part of one of said combined components extending into the sidemost section of the sole side of the sole forefoot area having the concavely rounded inner and outer surface portions extending up the sole side at least to the height of a lowest point of the sole inner surface of the same shoe sole side, as viewed in the shoe sole frontal plane during an upright, unloaded shoe condition.
