An insole may include an insole body in a shape receivable in a shoe; an electronic element provided in the insole body; a connection line configured to electrically connect to the electronic element and including a contact terminal exposed to the outside of the insole body; and a connector including a detachable member configured to at least partially protrude outward from the insole body and configured to support the contact terminal.

A compression garment for a neurological disorder includes a body portion and a pad. The body portion may be operable to wrap around a foot and the pad can attach to an inner surface of the body portion. The pad can include an outward protrusion and/or an inward recess. A guide sleeve may be dimensioned to wrap together with the body portion around the foot, the pad being disposable between the body portion and the guide sleeve. A first tensioning band may be attached onto to first and second locations of the body portion and be operable to secure opposing first and second portions of the inner surface of the body portion to secure the outward protrusion and/or recess of the pad against the abductor hallucis and flexor hallucis brevis muscles of the foot. The outward protrusion can include a receiver for the metatarsal head.

A footwear including a shoe body and a removable, heatable, inner sole is provided. The shoe body is shaped as footwear, for example, in the shape of a shoe, a slipper, a boot, etc. The removable, heatable, inner sole is placed between a sole and an insole of the shoe body. The removable, heatable, inner sole is rigid and is made of a material that can be heated repeatedly in a microwave oven for use within footwear. During use, the user can remove the removable, heatable, inner sole from the shoe body freely and conveniently, heat the removable, heatable, inner sole in the microwave oven, and place the heated inner sole between the sole and the insole of the shoe body. When the user wears the shoe body with the heated inner sole, the user can enjoy a soothing warmth and comfort provided by the heated inner sole.

A self-sustaining piezoelectric assembly is disclosed herein for providing electrical stimulation to nerves near the surface of the skin. The assembly comprises a non-conductive mat having an aperture and a piezoelectric device positioned to fill at least a portion of the aperture. A flexible conductive material is position to be in electrical contact with a first and a second primary surface of the piezoelectric device, and with the surface of the skin, providing an electric current to the skin when the piezoelectric is mechanically compressed.

A semi-rigid foot orthotic can have 3-axis accelerometers, gyroscopes, magnetometers, and strain gauges embedded in one or more flexible regions along with a microprocessor and wireless transmitter. Data from the sensors can be used to track the gait cycle. Data on the flexing, bending, or rotating of portions of the orthotic are processed and compared to ideal or data from other runs to rate the effectiveness of the orthotic. The orthotic and the sole of the shoe have relative freedom of motion between them. By doing a 3D comparing of the location, motion and orientation of the shoe from the same information for at least one orthotic region; determining shoe-to-orthotic relative motion. Modifications or adjustments can be made to improve the user-experience. The computation can involve either or both of a cloud based server and an external hand-held device in wireless communication with the orthotic.

A weight adjustable orthotic insert system includes an orthotic insert and a weight adjusting leaf. The orthotic insert corrects joint misalignment of a user based on a weight plus any additional load, foot flexibility or activity level (e.g., momentum) of the user. The weight adjusting leaf may be attached to the orthotic insert when the user is carrying a payload over a distance (e.g., a heavy pack or body armor) so that the orthotic insert provides the proper degree of correction given the increased weight instead of being collapsed by the additional weight.

A foot presence sensor system for an active article of footwear can include a sensor housing configured to be disposed at or in an insole of the article, and a controller circuit, disposed within the sensor housing, configured to trigger one or more automated functions of the footwear based on a foot presence indication. In an example, the sensor system includes a capacitive sensor configured to sense changes in a capacitance signal in response to proximity of a body. A dielectric member can be provided between the capacitive sensor and the body to enhance an output signal from the sensor.

An inner sole board having varying regions of flexibility is provided for use in an article of footwear. The inner sole board may include different materials along its length at different locations that vary its flexibility. An inner sole board is manufactured in an injection molding process requiring only one mold. The process includes a first step of providing a mold, a second step of providing an injection molding assembly, a third step of preparing an injection molding assembly and mold, a fourth step of injecting material into the mold, and a fifth step of establishing the dimensions of a first portion. During the injection molding process, the flow rate of at least one material may be controlled by a nozzle gate to control the shape and size of the flex zone it creates. In this manner, the inner sole board may be customized for a specific sport or individual.
