Abstract: An orthopedic walker boot for wearing on a lower limb of a wearer has a rigid external shell and a pliant internal boot received within the external shell. The internal boot includes a leg panel having an inflatable bladder and a pump panel having a pump for inflating the bladder. The leg panel is configured to wrap around a leg of a wearer and the external shell is sized and configured to receive the internal boot with the leg of the wearer wrapped therein. The pump panel has a first end fixably attached to the leg panel and has a selective and releasable operational orientation, wherein the pump panel is in an overlapping outer position relative to the leg panel.

Abstract: The invention relates to a shoe having an arch support extending from an interior of a shoe to an exterior of a shoe. The arch support can be adjusted from the exterior of the shoe. The arch support includes straps which each have a slide groove formed therein. On one end of each strap are strap eyelets. The shoe includes an upper having a slit opening separating an upper paneling and a lower paneling. The arch support is located within the shoe, and extends through the slit opening. Rivets connect the upper paneling and the lower paneling. The rivets are also aligned with and extend through the slide grooves on the arch support. Accordingly, the arch support straps may slide along the rivets to tighten or loosen the arch support within the shoe.

Abstract: Footwear comprising a sole. The sole has a heel section for supporting a heel of the foot. The heel section has medial and lateral regions. At least a portion of the lateral region has a first compressive resilience for attenuating the shock of impact to the wearer during running and walking. Further, the sole has an arch section forward of the heel section for supporting an arch of the foot. The arch section also has medial and lateral regions. At least a portion of the lateral region of the arch section has the first compressive resilience and at least a portion of the medial region of the arch section has a second compressive resilience harder than the first compressive resilience for providing firm support for the foot during running and walking. In addition, the sole has a forefoot section forward of the arch section for supporting a ball of the foot including first, second, third, fourth and fifth metatarsal heads and associated metatarsal necks, proximal phalanges and metatarsal phalangeal joints.

Abstract: A joint protective shoe construction for preventing knee and hip osteoarthritis is provided. The shoe construction includes a midsole or insole having a body with medial and lateral sides. The height of the lateral side of the body is greater than the height of the medial side, thereby forming a lateral wedge. A cantilevered arch support is also provided for transferring forces from the weight of the body to the lateral side of the shoe and foot. The arch support is adapted to support the medial side of an arch of a wearer's foot at a height above the ground. The lateral wedge and/or the arch support significantly reduce the knee and hip torques during walking, running, standing, or other weight bearing activities including athletic endeavors.

Abstract: The invention relates to an apparatus and methods for incorporating a medial/lateral counter foot stabilizer into shoes. In an embodiment, the medial/lateral counter foot stabilizer of the invention comprises a plantar aspect which extends the length of the sole of a foot, side walls, a metatarsal arch support, a lateral arch support, a medial arch support, and a heel cup counter. The stabilizer of the invention mimics a preferred foot shape, provides support for the metatarsal, medial, and lateral arches, and restricts pronation and supination of the foot. The stabilizer of the invention is designed to be integrated into commercial shoes during the manufacturing process as a method of providing foot support which is currently unavailable in commercial shoes.

Abstract: Footwear comprising a sole formed from a first resilient material for attenuating the shock of impact to a wearer during running or walking, and a second material harder than the first material for providing firm support for a foot. The sole has heel, arch and toe sections, each of which have medial and lateral regions. The sole also has a forefoot section having a first region for supporting the first, second, third, fourth and fifth metatarsal heads of the foot, associated phalanges and metatarsal phalangeal joints, and the metatarsal necks associated with the fourth and fifth metatarsal heads, and a second region for supporting the metatarsal necks associated with the second and third metatarsal heads.

Abstract: Footwear having an upper and a bottom, the bottom having an inwardly curved mid region, a protuberance is formed at the mid region which extends medially from the mid region beyond an imaginary line drawn from the widest part of the toe section of the footwear to the widest section of the heel of the footwear. In its preferred embodiments, the protuberance is convex in top plan view and convex in transverse sections starting from the widest area at the bottom of the protuberance and narrowing towards the top and in top plan view starting from a narrow front end of the protuberance being widest at midlength and then narrowing again at the end of the protuberance. Preferably, the protuberance is a medial extension of the longitudinal medial arch support of the footwear and has its vertical center line slightly rearward of the vertical center line of the longitudinal medial arch support.

The sole has heel, arch and toe sections, each of which have medial and lateral regions. The sole also has a forefoot section having a first region for supporting the first, second, third, fourth and fifth metatarsal heads of the foot, associated phalanges and metatarsal phalangeal joints, and the metatarsal necks associated with the fourth and fifth metatarsal heads, and a second region for supporting the metatarsal necks associated with the second and third metatarsal heads.

Abstract: A custom-made shoe of a sandal-type having a sole, an orthotic unit prescribed specially for the foot of the wearer adhered to the sole a vamp unit secured forwardly to the sole, and a counter secured to and projecting upwardly from the rear periphery of the sole.

Abstract: A shank for providing stability and torsional control to a shoe comprises a generally rectangular body having a pair of legs extending non-symmetrically from a first end for providing flexibility at the ball of the shoe, and a semicircular tab formed from a second end for enhancing the rigidity and torsional stability. A crested ridge formed along the underside of the shank provides stiffness to the shank's body while the legs allow for flexibility in the shank to accommodate the slight angular bending, twisting or sideways rocking that occurs at the ball of the shoe. From a side view, the body of the shank is curved to look like a generally elongated S-shape which follows the inclined form of a shoe lasting board. A stabilizer protruding in relief from the top side of the shank is used to align the shank with the shoe lasting board prior to permanent affixation.

Abstract: A foot correction method comprises the steps of raising a plantar arch (15) and applying a pressure on either side of a foot (13) to thereby maintain a configuration of a longitudinal arch and a transversal arch of the foot (13) so as to prevent and correct a spraying phenomenon of the foot (13). A splint (11, 23) for practicing the method comprises shape memory alloy wires preferably in the form of either woven fabric, such as a mesh (17), or a nonwoven fabric plate. The shape memory alloy wires preferably consists of a Ti-Ni series alloy exhibiting superelasticity at a normal or used temperature.

Abstract: An apparatus for providing footgear with comfortable individualized custom support, said apparatus comprising mechanical means to selectively and seperately change the position of multiple areas of the inner sole of said footgear, said areas corresponding generally to the areas of the foot described as the inner heel, the lateral arch, and the metatarsal area, and, whereas such changing of positions involves movement in two different directions: (1) upward and downward, (2) forward and backward, said changes in position are achieved by two different and seperate structures, wherein the movement of each of said structures is controlled by the selective turning of a screw, the heads of said screws being located on the outside of said footgear, where they can be selectively turned at any time.
