Abstract
An athletic shoe sole for a shoe has side portions with concavely rounded inner and outer surfaces, as viewed in at least a heel area and a midtarsal area of the sole. The concavely rounded portion of the sole outer surface located at the heel area extends substantially continuously through a sidemost part of the sole side. The rounded portion of the sole outer surface located at the midtarsal area extends up the sole side to at least a level corresponding to a lowest point of the sole inner surface. A midsole component of the shoe sole extends into the sidemost section of the sole side and also extends up the sole side to above a level corresponding to a lowest point of the sole inner surface. The concavely rounded portions of the sole midtarsal area are located at least at the sole lateral side. The sole outer surface of at least part of the midtarsal area is substantially convexly rounded, as viewed in a shoe sole sagittal plane.
