The invention is a sole for footwear having an indentation for the ball of the heel and a heel stop under the rear of the arch to prevent the foot from sliding forward in the footwear.
An orthotic shoe insert adapted to effectively control foot motion during gait to reduce trauma to various anatomical structures of the lower extremity and to increase gait efficiency. The orthosis comprises a unitary, curved wedge having a hook-like shape when viewed from above and includes a heel portion adapted to engage the sides of the heel, a middle portion adapted to engage the plantar side of the medial portion of the longitudinal arch, and a front portion adapted to engage the plantar side of the user's forefoot to a level just distal to the first and second metatarsal heads. The orthosis adjusts itself to different arch heights, and therefore may be fabricated without requiring custom fitting.
The invention is an orthotic system including a combination partial insole, heel cup and metatarsal pad. The combination partial insole is comprised of the heel cup, a modified metatarsal pad, a midfoot support and a longitudinal arch support. The heel cup and metatarsal pad may be used separately or in combination. Each of the structural elements of the system are designed to control the motion of a human foot during gait, as well as to attenuate shock to the foot during gait. Each of the structural elements of the system are self-adjustable for variations in foot and shoe size and are formed of a compression-resistant, deformable material without rigid components.
An article of footwear includes an outsole having a bottom walking surface and a depressed top surface surrounded by an upstanding peripheral sidewall having a upper peripheral edge, an upper attached to the outsole, and a replaceable inner sole. The upstanding peripheral sidewall and depressed top surface of the outsole together define a cavity lying generally below the upper peripheral edge. The upper and outsole together define a volume disposed over the cavity and generally above the upper peripheral edge, the volume sized comfortably accommodate a wearer's foot. The replaceable inner sole has a body sized and shaped to fit snugly within the cavity portion, generally removed from encroachment of the volume, while supporting a wearer's foot within the volume.
An arch support device has a periphery shaped to conform to at least part of the periphery of the sole of a wearer's footwear, an upper surface, a lower surface, a heel region, an arch region, and a toe region, each region being designed to lie under the corresponding regions of a wearer's foot when in use. At least part of at least one of the surfaces of the device has a slip-resistant surface texture for resisting slipping, with the textured surface formed during injection molding of the device in a mold which is roughened over at least part of its surface. Slip-resistant surface portions on both the upper and lower surface will resist slipping of a wearer's foot relative to the device and slipping of the device relative to the footwear.
