20110126422 | SHOE SOLE WITH COMPRESSIBLE PROTRUDING ELEMENT - 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. | 06-02-2011 |
20120137540 | COMPOSITE SOLE ASSEMBLY - 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. | 06-07-2012 |
20120304489 | FOOTWEAR PROMOTING NATURAL MOTION - 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. | 12-06-2012 |
20120317844 | OUTSOLE WITH PODS AND GROOVES - An outsole designed to enable stability when standing, facilitate sole flexibility and encourage unhindered natural foot motion between the foot and the ground, the outsole including a top face and a bottom face, the bottom face having a plurality of anatomically placed pods for engaging directly with a walking surface, and a plurality of contact points forming a stable platform for the wearer while standing, the top face including a flex groove matrix having a first plurality of grooves which extend transversely across the top face from the inside of the foot to the outside of the foot and intersect with at least some of a second plurality of grooves which extend longitudinally at least partially across the top face from heel to toe. | 12-20-2012 |
20120317845 | PRESSURE RELIEF SYSTEM FOR FOOTWEAR - 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. | 12-20-2012 |
20130318817 | FOOTWEAR WITH INTEGRATED ENERGY WAVE SOCKLINER - A shoe assembly is designed to enable unhindered natural foot motion between the foot and the ground. The shoe assembly includes an integrated anatomically shaped sockliner and outsole. The sockliner includes a top face and a bottom face, each having a generally planar surface, extending along a base plane. On the top face of the sockliner, a plurality of grooves extend across the base plane in a generally undulating pattern for engagement with the sole of the foot. The bottom face of the sockliner may include a plurality of alternating ridges and/or valleys extending from the inside to the outside of the foot in a generally undulating pattern for engagement with the outsole. A strobel insole of encapsulated high resiliency foam may be positioned between the sockliner and the outsole. An optional midfoot support element may be positioned between the insole and outsole to control tortional stiffness. | 12-05-2013 |
20130326905 | ENERGY WAVE SOCKLINER - 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. | 12-12-2013 |
20140068965 | GEL PAD FOR FOOTWEAR - A gel pad for use in a sockliner designed to strategically support the weight of the wearer and to distribute underfoot pressure. The gel pad includes a base having a top face, a bottom face and a central floor portion associated with the bottom face, an outer flange positioned on the perimeter of the bottom face surrounding the central floor portion, and a plurality of spaced apart hollow pillars positioned across the surface of the central floor portion. The network of hollow pillars support the body weight of the wearer without bottoming out and the pillars are sufficiently spaced from each other to allow for expansion horizontally when the pillars are compressed vertically. Each of the pillars may be substantially octagonally shaped. | 03-13-2014 |
20140137431 | MULTIPLEX SOCKLINER SYSTEM - A sockliner for use in a shoe assembly designed to strategically distribute underfoot pressure and to facilitate air circulation within a shoe. The sockliner includes a base having a top face, a bottom face and a plurality of perforation holes positioned across the length of the base and extending therethrough. The sockliner further includes a plurality of ventilation grooves located along a peripheral edge of the sockliner designed to cooperate with the perforation holes to encourage air flow. The bottom face of the sockliner further includes a plurality of zones, each zone including a plurality of lugs which are strategically designed and located to support the weight of the wearer and provide cushioning to the wearer's foot. | 05-22-2014 |
