Abrégé

A sockliner for integration into a shoe assembly including a top face and a bottom face, each having a generally planar surface, extending along a base plane. On the top face, a plurality of grooves extend across the base plane in a generally undulating pattern for engagement with the sole of the foot. On the bottom face, a plurality of alternating ridges and/or valleys extend from the inside of the foot to the outside of the foot in a generally sinusoidal pattern for engagement with the outsole. The bottom face having a plurality of ridges positioned parallel and above the base plane, extend downwardly and a plurality of valleys positioned parallel and below at the base plane, extend upwardly. The combination of the generally undulating geometry of the top face and the generally sinusoidal geometry of the bottom face built into the structure of the sockliner for providing support and cushioning integrated into a shoe assembly.

Abrégé

A shoe is designed to enable unhindered natural foot motion between the foot and the ground. The shoe is constructed with a cupped heel, a contoured arch, a radiused forepart and neutral heel/forefoot position to create a foot bed that anatomically cradles a wearer's foot. A soft, flexible strobel stitched insole is added, which utilizes encapsulated high resiliency foam. The outsole is sculpted to have rounded natural edges and an anatomically correct flex location toward the forefoot of the shoe where softer, more flexible materials are used. The outsole is further designed with harder, protective materials strategically placed in high ground-contact areas to deliver protection and support. An optional midfoot support element may be positioned between the insole and outsole to control torsional stiffness. Upper materials are selected to minimize restriction of movement and promote breathability.

Abrégé

A shoe having a last which includes a shape and volume that reflects the thickness of an internal sock liner, and a shoe interior made specifically for inclusion of the sock liner. The sock liner itself includes an anatomically shaped foot bed surface with a cupped heel, contoured arch, radiused forepart and beveled toe area. The sock liner material specifications and thicknesses are engineered or tuned to have a high amount of deflection when compressed without getting stiff.

Abrégé

A composite sole assembly for attachment to an outsole of suitable material, the sole assembly including a chassis, a forefoot pad and a heel pad. The chassis includes an opening for receiving the heel pad and further includes two peripheral flanges for securing attachment with the shoe upper. A cushioning forefoot pad is positioned between the chassis and the outsole and between the two peripheral flanges and is formed of a soft cushioned foam material. The top surface of the chassis and the heel pad define a raised area in the midfoot region and a recessed area in the heel region of the assembly to better conform to the anatomical shape of a wearer's foot. The combination of the raised and recessed areas along with the positioning of the heel and forefoot pads improves comfort and provides for a better distribution of foot pressure during a normal gait.

A midsole adapted for attachment to a shoe having multiple layers of varying materials each having a different hardness level. More particularly, the present midsole includes a top, middle and bottom layer wherein all three layers of material have a different hardness range and wherein at least one of the layers is made from thermoplastic rubber (TPR). In one embodiment, the thermoplastic rubber (TPR) layer lies between the top and bottom layers and in another embodiment, the thermoplastic rubber (TPR) layer is the bottom layer. The thermoplastic rubber (TPR) layer may also have a length shorter than the other two layers forming the midsole.

Abrégé

A footwear sole assembly with at least one compressible protruding element extending downwardly beyond the bottom surface of the outsole, the at least one protruding element providing a natural instability to a wearer when the sole assembly initially contacts a supporting surface. The at least one protruding element is a three-dimensional structure formed of a substantially solid elastomeric material. In another embodiment, the at least one protruding element may also protrude upwardly beyond the sole assembly in such a manner that the wearer's foot can apply pressure to the top portion of said at least one protruding element.
