Abstract: The present invention is a shoe sole comprising an array of elliptical cells, wherein each cell has a wall, and wherein each cell wall is conjoined to or contiguous with at least one other cell wall. The cell wall may be conjoined to another cell wall by a conjoining element. At least some of the cell walls buckle when compressive or shear force is applied during use. The sole is made from any material with elastic properties for this application. The shoe sole can further comprise a substrate, also made of elastomeric material, integrated with the cell walls at their upper level, lower level, or their periphery, forming a unitary piece. Variations can be made as to the dimensions and arrangement of these cell walls. This sole can be incorporated into a shoe sole assembly as a shoe midsole.

Abstract: A shoe having a shock absorbing bottom comprising one or more compartments filled with gas, for example air or nitrogen and which functions as a spring and one or more dampers which function to control rebound and vibrations. The damper can be viscoelastomeric material.

Abstract: The present invention comprises a multilayered heel construction for footwear. A fluid-filled bladder is incorporated into the heel of footwear. The bladder defines an internal cavity which is adapted to enclose a fluid at atmospheric pressure. The internal cavity defines a peripheral channel adjacent the periphery of the bladder and a plurality of intersecting channels orientated transversely to the longitudinal axis of the footwear. The intersecting channels are in communication with the peripheral channel of the interior cavity. The bladder is positioned at the heel of the footwear and is positioned intermediate an upper footbed support. The lower surface of the multilayered heel assembly defines a concave, cantilever surface. The combination of the bladder, the upper footbed support and the lower cantilever surface improve shock absorption and the stability of the footwear.

Abstract: The invention is directed to a midsole assembly for footwear which includes medial and lateral unsymmetrical stabilizing pods disposed between shock absorbing upper and lower deflectable plates positioned at the heel portion of the midsole. The bottom surface of the heel portion of the midsole includes an axially aligned deflection platform defined by a concave surface. The upper shock absorption plate is disposed adjacent the bottom surface of the midsole and includes an aperture therethrough which is adapted to receive the deflection platform. The bottom plate includes a deflectable concave segment which is aligned with and adapted to engage the deflection platform of the midsole and be urged downwardly upon the imposition of force upon the midsole by the user's foot.

The upper plate is adapted to engage the bottom surface of the midsole and includes an axially aligned, concave segment which is resiliently deflected upon the imposition of force thereon by the user's foot. The bottom plate includes a deflectable concave segment which is adapted to engage the deflectable segment of the upper plate and be urged downwardly upon the imposition of force upon the upper plate by the user's foot. The medial and lateral stabilizing pods are mounted between the upper and lower plates along the medial and lateral sides of the heel portion of the midsole and are respectively adapted to dynamically respond to the forces imposed on the medial and lateral sides of the heel.

Abstract: The construction of a shoe which includes shock attenuating members in the forefoot and heel thereof. The shock attenuating members in the heel of the shoe are in the form of a pair of vertically spaced, resilient cantilevered members, each of which comprises a substantially U-shaped air chamber having a load alignment surface for centering loads at heal strike while concurrently transferring peak loads to the outer perimeter of the cantilevered shock attenuating members. The forefoot shock attenuating member comprises a plurality of segmented air chambers in a planar relationship with each other disposed between the midsole and outsole at the forefoot thereof to properly balance and stabilize loads during running and concurrently maximize durability, cushioning and comfort.
