A system for analysis of user gait and to provide correction in form of haptic and visual feedback. This system comprises a motion and force sensors and a haptic actuator embedded in the user shoe insoles in communication with a smart-phone based analysis application, configured to calculate motion and orientation of the user feet in relation to the value, location and distribution of ground reaction forces measured by sensors located in the shoe insoles and after analysis of said forces and motion, to provide haptic feedback to the user foot instructing about the location (and timing) of pressure the user must apply to achieve an optimal gait.

A foot alignment tool is configured for aligning a foot bearing a load. The tool extends between a handle at one end and a support lever at an opposing end and is characterized in that the support lever is configured to be received under or substantially under the medial longitudinal arch or the cuboid of the foot and configured to be rotated so as translate and/or rotate the foot from the inside of the foot to the outside of the foot or from the outside of the foot to the inside of the foot by a predetermined amount about a foot heel-toe axis wherein the support lever is configured to apply a predetermined torque.

The enclosed describes a sensor pad for wearing on a human body. The sensor pad is configured to be in contact with a substrate having a contoured surface, such as a surface of the body. The sensor pad comprises at least a sensor layer and a stiffener layer. The sensor layer comprises a surface area defining a sensing area configured to measure value at a plurality of locations of the sensing area. The stiffener layer is couples to the surface area of the sensor layer. The stiffener layer has a micro-cut pattern to reduce mechanical resistance of the stiffener layer. The micro-cut pattern facilitates the stiffener layer in stretching or compressing in one or more predefined directions, enabling the stiffener lay to conform to the contoured surface of the substrate.

An orthopedic shoe appliance includes a pad for providing support for midfoot arches, the second metatarsal, and the third metatarsal of a foot, wherein the pad does not provide substantial support under a heel of the foot or under the first metatarsal, the fourth metatarsal, and the fifth metatarsal. A method for manufacturing an orthopedic appliance includes obtaining a pad; and shaping the pad to provide support for midfoot arches, the second metatarsal, and the third metatarsal of a foot, but not provide substantial support under a heel of the foot or under the first metatarsal, the fourth metatarsal, and the fifth metatarsal.

An insole, which is insertable into a shoe and is removable from the shoe, includes at least a top layer, a middle layer, and a bottom layer. The middle layer has apertures or cavities, that define several discrete storage chambers within the insole. Each storage chamber stores a mixture of two or more particulate materials. The mixture includes one or more materials selected from Group A, which includes natural sand, synthetic sand, artificial sand, kinetic sand, silica, quartz. The mixture further includes one or more materials selected from Group B, which includes: powdered aluminum, powdered titanium, powdered zinc, powdered magnesia, powdered silver, powdered anti-bacterial agent, powdered metal, powdered talcum, grained cork, grained coal, grained wood.

[Problem] To provide a shoe insole that can inherently maintain appropriate meshing with foot joints at a high level. [Solution] A sheet section, disposed on the entire base of a shoe, and a support plate, formed from a material harder than the sheet section are provided. The sheet section and the support plate each comprises an inner curved surface section, curved in an arch shape with an end section standing upward, an outer wall section, curved in an arch shape, with an end section standing upward, and a central wall section, formed between the inner wall section and the outer wall section. The support plate comprises an inner ridge section, formed on the boundary between the inner wall section and the central wall section, and an outer ridge section, formed on the boundary between the outer wall section and the central wall section. A plurality of through-holes, arranged in the longitudinal direction of the support plate, are formed in the inner wall section and the outer wall section of the support plate. At least an upper surface of the central wall section located between the inner ridge section and the outer ridge section is curved so as to draw an arch in the longitudinal direction of the support plate.
