Abstract: In its simplest conceptual form, this invention relates to variations in the structure of such shoes having a sole contour which follows a theoretically ideal stability plane as a basic concept, but which deviates substantially therefrom outwardly, to provide greater than natural stability, so that joint motion of the wearer is restricted, especially the ankle joint; or, alternately, which deviates substantially therefrom inwardly, to provide less than natural stability, so that a greater freedom of joint motion is allowed. Alternately, substantial density variations or bottom sole designs are used instead of, or in combination with, substantial thickness variations for the same purpose. These shoe sole modifications are research indicating that they are necessary and useful to correct important interrelated anatomical/biomechanical imbalances or deformities of surprising large magnitude in both individuals or major population groups.

Abstract: An article of footwear including a sole and an upper with an exterior and interior surface, and a bladder which comprises at least one of the exterior or interior surfaces. The bladder comprising sheets of polyurethane attached together via welding. The bladder includes a medial compartment and a lateral compartment attached to each other under the foot of the wearer. The article of footwear also includes a inflation mechanism for selectively introducing air to the chambers.

Abstract: A custom conformable device that supports and cushions a user's anatomical part, such the foot. The device is self-inflating, conforms to the shape of the user's foot, utilizes an inflatable bladder with a valve, and contains an expandable material such as an open cell foam. When the valve is open the expandable material expands, causing the bladder to inflate and to conform to the shape of the user's anatomical part. Once the desired shape is achieved, the valve is closed, sealing the bladder. Once the bladder is sealed, the expandable material retains the shape of the user's anatomical part. The user may open the valve to adjust the level of support provided by the device by allowing more fluid to enter the bladder, or by forcing fluid to exit the bladder.

Abstract: An orthotic insert having an angled lateral surface that engages the insole so as to pivot the insert in a lateral direction and invert the rearfoot at heel strike, and a medial bottom surface that freely interfits within the heel counter and insole of the shoe so as to avoid limiting pivoting motion in the medial direction as the weight on the foot shifts forwardly and medially. Pivoting motion in the medial direction is arrested by engagement between a distal medial portion of the rigid plate member and the insole along the transverse plane of the shoe. The distal medial portion of the plate member is located generally proximal and beneath the first metatarsal head of the foot. The upwardly angled medial surface of the post permits the post to fit optimally within the heel area of the shoe and also avoids interference between the heel counter/insole and the post that would impair proper operation of the insert.

Abstract: A structural chassis includes a structural chassis and a foam chassis or sock liner sandwiched together to form an assembly that can be inserted into and substantially occupy a footbed of a shoe upper. Discrete sole elements are attached to a bottom side of the upper so as to expose certain portions of the bottom side therebetween. This absence of outsole material in those areas makes the upper collapsible about those areas since the outsole provides no support in those areas. Instead, the structure is provided by the chassis of the chassis, which is customized to the user's foot by placing one or more notches in strategic locations along the chassis where the foot naturally flexes. One such notch is located on the chassis in a position that allows the chassis to flex about a forward push-off axis of the foot that runs through the first and second MTP joints.

The bulges include concavely rounded inner and outer portions for approximating the structure of and support provided by the natural foot. The bulges can be located proximate to important structural support areas of an intended wearer's foot on either or both sides of the shoe sole or the middle portion of the shoe sole, or on various combinations of these locations. The bulges include side and upper midsole portions to improve stability while also improving cushion and comfort. The bulges can be tapered as viewed in a horizontal plane to improve flexibility and reduce unnecessary weight.

Abstract: A shoe having an anthropomorphic sole that copies the underlying stability, support, and cushioning structures of the human foot. Natural stability is provided by attaching a completely flexible but relatively inelastic shoe sole upper directly to the bottom sole, enveloping the sides of the midsole, instead of attaching it to the top surface of the shoe sole. Doing so puts the flexible side of the shoe upper under tension in reaction to destabilizing sideways forces on the shoe causing it to tilt. That tension force is balanced and in equilibrium because the bottom sole is firmly anchored by body weight, so the destabilizing sideways motion is neutralized by the tension in the flexible sides of the shoe upper. Support and cushioning is provided by shoe sole compartments filled with a pressure-transmitting medium like liquid, gas, or gel. Unlike similar existing systems, direct physical contact occurs between the upper surface and the lower surface of the compartments, providing firm, stable support.
