Patent ID: 8261468

Claim:
A shoe comprising: a shoe upper and a shoe sole including at least a bottom sole; at least a portion of said shoe sole being formed by an insertable midsole orthotic having an inner surface and an outer surface; 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, as viewed in a frontal plane cross-section when the shoe sole is upright and in an unloaded condition; the inner surface of the insertable midsole orthotic including at least one convexly rounded portion, said convexity being determined relative to a portion of the insertable midsole orthotic directly adjacent to the inner surface of the insertable midsole orthotic, as viewed in a frontal plane cross-section when the insertable midsole orthotic is upright and in an unloaded condition; the outer surface of the insertable midsole orthotic including at least one concavely rounded portion, said concavity being determined relative to a portion of the insertable midsole orthotic directly adjacent to the outer surface of the insertable midsole orthotic, as viewed in a frontal plane cross-section when the insertable midsole orthotic is upright and in an unloaded condition; each said concavely rounded portion of the outer surface of the insertable midsole orthotic being located on the insertable midsole orthotic at a location corresponding to the location of at least one convexly rounded portion of the inner surface of the insertable midsole orthotic so as to define a rounded portion of the insertable midsole orthotic located between said convexly rounded portion of the inner surface of the insertable midsole orthotic and said concavely rounded portion of the outer surface of the insertable midsole orthotic, as viewed in a frontal plane cross-section when the insertable midsole orthotic is upright and in an unloaded condition; the insertable midsole orthotic including at least two computer controlled compartments, each compartment containing a fluid, and wherein at least a part of each of said at least two computer controlled compartments is located in a single frontal plane cross-section of the shoe sole when the shoe sole is upright and in an unloaded condition; and at least one duct and/or valve providing fluid communication between said at least two computer controlled compartments.
