Abstract: An apparatus includes a heel section, a mid-foot section, and a toe section. The heel section, the mid-foot section, and the toe section collectively have a geometric shape having a first slope of a polarity along an inner edge of the apparatus from the toe section to the heel section and a second slope of the polarity along the inner edge of the apparatus to an outer edge of the apparatus at the toe section.

Abstract: A foot balancing device includes a shoe insert, a main balancing element, three auxiliary force-transferring elements, and three auxiliary balancing elements. The main balancing element is provided in an arch region of the shoe insert and serves as a fulcrum on the shoe insert for the front part of the sole of one of the user's feet and the heel of the foot. The auxiliary force-transferring elements are provided in the arch region of the shoe insert so that the pressure center of the sole will displace along an ideal line. The auxiliary balancing elements are located forward of and on two lateral sides of the main balancing element respectively to support a transverse arch, inner arch, and outer arch of the foot respectively. Thus, the user's body weight can distribute evenly over the sole while the user is standing or walking, thereby preventing injury resulting from improper posture.

Abstract: A barefoot orthotic is a foot support that adheres to the underside of a user's foot and is placed so that it extends longitudinally between the metatarsal head region and the calcaneal plantar tuberosity, and laterally between the lateral midfoot and the medial arch. By using a silicone polymer or other similar material, a barefoot orthotic can self-adhere to the skin of a user's foot. A barefoot orthotic can have a midfoot strike zone surrounding the forward portion of the calcaneal plantar tuberosity, a navicular support, a medial arch support, a forefoot propulsion pad, a lateral forefoot support, a lateral midfoot support, a cuboid support flange, a lateral heel support, and a balance rail extending longitudinally from the midfoot strike zone to the forefoot propulsion pad. Together, these components work to support and align the foot and thereby alleviate symptoms of various foot and leg conditions.

Abstract: An orthotic is disclosed. The orthotic has a convex element that has a periphery. The convex element is positioned in a plane. The periphery is structured and arranged to deform into a gap in at least of a horizontal, a vertical, or a lateral direction relative to the plane. The convex element is structured and arranged for placement between a plantar surface of a foot and a second surface. The gap is defined by a top surface of the convex element and a bottom surface of the foot or a bottom surface of a body of an insert. The periphery of the convex element is structured and arranged to deform into the gap as a force is applied to the body and to rebound as the force dissipates.

Abstract: An insole assembly for footwear includes a cushioning member and an underlying resilient support member. The cushioning member has an undersurface with a first region beneath a wearer's heel and a second region extending beneath a wearer's arch. The resilient support member has a body and at least one resilient cantilevered arm with a first end attached to the body and a second end extending beneath the second region of the cushioning member. The cantilevered arm defines an arch support surface in supporting engagement with the undersurface of the cushioning member.
