A half-orthotic insert beginning at the heel and extending to the metatarsal region of the foot having raised elements that align with the fascia ligament for the purpose of providing relief of plantar fasciitis.

Sole for footwear that includes configurations that improve the cushioning in a user's tread with respect to known soles, comprising a lower layer and a side wall, the lower layer comprising a front part, a middle part and a rear part; in at least one portion of the front or rear part of the lower layer there are at least two protrusions, each arranged and extended transversely to the longitudinal axis of the sole and each of them comprising a first segment in contact with the lower tread and a second segment; between the side ends of each protrusion and the side wall there is a first separation that allows the full bending of each protrusion, the second segment being inclined with respect to the first segment; between two adjacent protrusions there is a second separation so that the second segment rests at least partly on the adjacent protrusion.

Footwear for use during a specialized activity such as skiing, cycling, skating and many other sports or industrial uses, and provides a dorsal element engaging the dorsal aspect of the foot for enabling the user to control relative to the plantar aspect the maximum height of the arch of the foot at substantially all times during the activity regardless of the position or orientation of the foot. A pivotal arm is mounted on a frame attached to the planter aspect for pivotal movement about an axis transverse to the foot and is compressed by an adjustable element operable by the user.

A sandal that uses a pump and bladder system to provide foot arch support a user. The sandal uses a strap system that defines a pump and a tubing system that attaches to the front and instep of a sandal. The instep of the sandal defines an air bladder that connects to the tubbing system. The air bladder inflates and provides arch support to a user of the sandal.

High resiliency foams are provided as well as articles and components formed therefrom. In various aspects, resin compositions are provided including a compatibilized polymer blend of a first ethylene vinyl acetate copolymer and an olefinic thermoplastic elastomer. In some aspects, the resin compositions can include about 65 parts per hundred resin to about 100 parts per hundred resin of the compatibilized polymer blend, about 0 to about 20 parts per hundred resin of a second ethylene vinyl acetate copolymer; about 0.1 parts per hundred resin to about 5 parts per hundred resin of zinc oxide; about 1 parts per hundred resin to about 10 parts per hundred resin of calcium carbonate; about 1 parts per hundred resin to about 10 parts per hundred resin of a chemical blowing agent; and about 0.1 parts per hundred resin to about 1.5 parts per hundred resin of a crosslinking agent.

The present invention is for a footwear apparatus for improved gait bio mechanics. In accordance with an embodiment of the invention, the footwear apparatus may comprise a heel cup that provides a valgus tilt to a user's good and provides a deep heel cup to adequately support the user's heel. It may also be comprised of a medial arch support member and a midfoot lateral support member, wherein the heel cup, the medial arch, and the midfoot lateral support member stabilize the user's foot in a lateral direction to minimize pronation and heel inversion.

This invention relates to a shoe insole comprising an inner sole having one or more of a support portion in the rearfoot exterior quadrant, a cushioning portion in the forefoot interior quadrant, a cushioning portion that extends from the forefoot interior quadrant to the forefoot exterior quadrant, and a cushioning portion in the rearfoot interior quadrant and the rearfoot exterior quadrant. Methods of making, using, and positioning the disclosed shoe insole and the components thereof are also described. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
