Abstract: A sole for a shoe or other footwear. The sole includes at least two structures, each structure being configurable, and wherein at least a part of each of said at least two structures is located in a single frontal plane cross-section of the sole when the sole is upright and in an unloaded condition. The sole also includes at least one electronic control system that controls a configuration of each said at least two structures. Optionally, the at least two structures and/or the at least one electronic control system are located in a midsole section of said sole.

Abstract: This invention relates generally to footwear such as a shoe, including an athletic shoe, with a shoe sole, including at least one removable midsole section formed by a midsole portion, wherein the removable midsole section is non-orthotic. The removable midsole section is inserted within the shoe upper, the sides of which hold it in position. The shoe sole includes a concavely rounded side or underneath portion, which may be formed in part by the removable midsole section. The removable midsole section may extend the length of the shoe sole or may form only a part of the shoe sole and can incorporate cushioning or structural compartments or components. The removable midsole section provides the capability to permit replacement of midsole material which has degraded or has worn out in order to maintain optimal characteristics of the shoe sole.

Abstract: This invention relates generally to footwear such as a shoe, including an athletic shoe, with a shoe sole, including at least two computer controlled compartments, each compartment containing a fluid. 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 sole when the sole is upright and in an unloaded condition. The sole also includes a duct providing fluid communication between each of said at least two computer controlled compartments. The sole may include fiber and/or an internal sipe and the computer controlled compartments may be encapsulated by fiber or an internal sipe.
