1. A shoe comprising: a shoe upper and a shoe sole including a least a bottom sole; at least a portion of said shoe sole being formed by an insertable midsole orthotic; at least a portion of the sides of said shoe upper being attached directly to the bottom sole such that the shoe upper envelopes, on the outside, at least the insertable midsole orthotic of said shoe sole, such that the insertable midsole orthotic of said shoe sole is located within a structure formed by a combination of said bottom sole and a portion of said shoe upper that is attached to said bottom sole; the inner surface of the shoe sole including at least one convexly rounded portion, said convexity being determined relative to a portion of the shoe sole directly adjacent to the inner surface of the shoe sole, as viewed in a frontal plane cross-section when the shoe sole is upright and in an unloaded condition; the outer surface of the shoe sole including at least one concavely rounded portion, said concavity being determined relative to a portion of the shoe sole directly adjacent to the outer surface of the shoe sole, as viewed in a frontal plane cross-section when the shoe sole is upright and in an unloaded condition; each said concavely rounded portion of the sole outer surface being located on the shoe sole at a location corresponding to the location of at least one convexly rounded portion of the sole inner surface so as to define a rounded portion of the shoe sole located between said convexly rounded portion of the sole inner surface and said concavely rounded portion of the sole outer surface, as viewed in a frontal plane cross-section when the shoe sole is upright and in an unloaded condition; and wherein at least a rounded part of each said rounded portion of the shoe sole between parallel rounded portions of the sole outer surface and inner surface has a uniform thickness, and said rounded portion part of the shoe sole which has a uniform thickness extends from a lowest point of the shoe sole to at least a sidemost extent of the side of the shoe sole, as viewed in a frontal plane cross-section when the shoe is upright and in an unloaded condition.
