An ankle brace for treating or preventing a high ankle sprain is disclosed. The ankle brace includes a body configured to be worn over an ankle. A tightening mechanism is attached to the body and configured to tighten the body around a wearer's lower leg to prevent distal ends of the tibia and fibula from separating. A torsion strap is attached to the body and configured to wrap from a fifth metatarsal to a medial malleolus to limit external rotation of the foot. The ankle brace can include lateral and medial straps for limiting eversion and inversion of the foot. The ankle brace can include heat moldable lateral and medial support plates.

To provide an insole capable of effectively inhibiting hallux valgus. An insole in which a heel configured so as to make a human heel arranged higher than a toe when worn is fixed on a back surface side, an upper is fixed on a upper surface side, and an outsole is fixed on the back surface side, the insole having: a stamping-part support part to support a stamping part of a foot of a user; a plantar-arch corresponding part contiguously connected to the stamping-part support part, having a tilt rising toward a rear end part direction, and corresponding to a plantar arch of the foot of the user; and a heel support part contiguously connected to the plantar-arch corresponding part, wherein the heel support part has a concave part to be able to enwrap the heel of the user.

Orthotic devices for providing arch support for the foot are disclosed. The orthotic device includes a base member, an arch support portion, and a covering for coupling the arch support portion to the base member. A method of providing continuous contact with the plantar surface of the foot during all phases of the gait cycle is also disclosed. In addition, methods of assembling and using the orthotic device are also disclosed.

Devices with internal flexibility sipes, such as slits, provide improved flexibility, improved cushioning to absorb shock and/or shear forces, and improved stability of support. Siped devices can be used in any existing product that provides or utilizes cushioning and stability. These products include human and other footwear, both soles and uppers, as well as orthotics; athletic, occupational and medical equipment and apparel; padding or cushioning, such as for equipment or tool handles, as well as furniture; balls; tires; and any other structural or support elements in a mechanical, architectural, or any other product.

An athletic footwear artificial ligament device includes a flexible band securable around a lower leg above an ankle of a foot of a wearer, a ring disposable adjacent an outer side of the ankle spaced below the flexible band, and a plurality of artificial ligaments coupled to and arrayed about the ring. An upper artificial ligament is attached to the flexible band and extends downward to the ring. A lower artificial ligament is attachable to an upper of the athletic shoe, adjacent to the sole and above the heel, and extends upward to the ring. A forward artificial ligament is attachable to the athletic shoe upper forwardly of the ring, above the sole and spaced forwardly from the heel, and extends rearward to the ring such that the artificial ligaments perform as a second set of ligaments providing sprain protection of the ankle of the foot of the wearer.

Components for articles of footwear and athletic equipment are provided including a high energy return foam having improved abrasion resistance. A variety of foams and foam components and compositions for forming the foams are provided. In some aspects, the foams and components including the foams can have exceptionally high energy return while also having improved durability and softness and an improved abrasion resistance. In particular, midsoles including the foams are provided for use in an article of footwear. Methods of making the compositions and foams are provided, as well as methods of making an article of footwear including one of the foam components. In some aspects, the foams and foam components can be made by injection molding or injection molding followed by compression molding.

A boot includes a rigid outer shell including a base portion adjacent to a portion of a foot of a subject, a leg portion adjacent to a portion of a leg of the subject, and an ankle support portion integral with and coupling the base portion of the main body with the leg portion of the main body, the ankle portion of the main body being adjacent to two opposing sides of an ankle of the subject, the ankle support portion of the main body having one or more removable elements. A first one of the one or more removable elements, adjacent to a first one of the two opposing sides of the ankle, is configured to be removed from the rigid outer shell to aid in preventing contact between an incision area on the first side of the ankle of the subject and the rigid outer shell.

Foot support components include plural foot support members (e.g., arched slats or other support members) forming at least a portion of a footbed for a sole structure/article of footwear. Spacings between individual foot support members enable selective activation of one or more individual members, thereby providing support where needed and enhancing overall comfort without overly stiffening the footbed. When made from sufficiently rigid/resilient materials, the foot support components may apply return energy to the wearer's foot. This may occur, for example, by vertically deflecting (e.g., flattening out) one or more foot support members under applied force, and then the deflected foot support member(s) will spring back to and/or toward its/their original shape when the force sufficiently abates/relaxes.
