A method and wearable system and for enhancing human balance and gait and preventing foot injury through neurological stimulation of the foot and the ankle. Subthreshold stimulation for neurosensory enhancement is provided via electrodes or vibrational actuators, or combination thereof, disposed in or on a wearable a platform, such as an insole, sock shoe, removable shoe insert, or applied without the support of a platform, to the skin surface of an individual. Suprathreshold stimulation for therapeutic purposes, such as improving blood flow, is also provided by the vibrational actuators. The actuators and electrodes are driven by bias signals generated by a bias signal generator that is coupled to a controller. The signal generator under the control of the controller is adapted to generate a non-deterministic random signal, a repetitive pattern or series of patterns. The controller optionally includes a communication port for interfacing with an external computer for purposes of optimizing and programming the controller. The wearable system is powered by a power source.

A three-dimensional sock-shoe includes a shoe sole, a sock body having a bottom portion connected to the shoe sole, and a foam sleeve inserted into the sock body. The foam sleeve has a shape corresponding to that of the sock body, defines a three-dimensional foot space, and is made by stitching together at least two layered structures. The foam sleeve successively consists of an inner lining layer, a foam layer and an outer fabric layer. At least one adhesive layer is disposed between the outer fabric layer and the sock body to adhere the outer fabric layer to the sock body.

This invention describes a kind of multipurpose waterproof zipper shoe, including shoe sole, upper, optical sensor, controller, power source and control switch. One end of the upper is connected to shoe sole. The upper is equipped with an opening that has a waterproof zipper. The front end of the upper is armed with optical sensor, buzzer, controller, and light, and at one side of the upper, there is power source and control switch. Both the shoe sole and upper are equipped with a waterproof layer, which can attain the goal of water proofing. The cavity of the shoe sole is equipped with a shoe cover so that the shoe can be put into shoe cover in case of dirty road to prevent the shoe from being smudged. The shoe sole is armed with several sheets for magnetic therapy, which can provide continuous magnetic massage for feet to dredge main and collateral channels and address the problem of deficiency in vital energy and blood. This product is equipped with an optical sensor that can sense road conditions, a controller that controls the light, and a buzzer that alerts users.

A support material having an hourglass shape reduces the cost of manufacturing as well as increasing comfort and air circulation. The support material includes a primary end having a primary diameter located opposite a secondary end having a secondary diameter. A substantially central portion of the support material has a tertiary diameter being a size less than the primary and secondary diameters. Additional improvements include an improved outer wall surface of the support material having at least one recess. The at least one recess can retain a substance such as a cooling gel.

Provided is a shoe, including: shoe body, and a pressure sensor, a controller and a prompting device arranged on the shoe body, in which the pressure sensor is operated to detect a pressure of a position of the shoe body, and when the pressure sensor detects that a pressure in a first position of the shoe exceeds a threshold, the controller controls the prompting device to indicate a prompt of the pressure of the first position exceeding the threshold.

A flexible foot abduction apparatus allowing movement in a horizontal and vertical plane with an elongated member made of a shape memory material. The elongated bar is shaped such that it has both vertical and horizontal aspects to allow a user to more easily manipulate the apparatus in one or both planes. The elongated member has an original shape which can be selectively forced into a second shape by a user and then return to the original shape.

A temperature modifying system for footwear having an air diverter positioned on top of the rear portion of the shoe insole, bores passing from an insole aperture beneath the air diverter to a supply port, and an AC system adapted to deliver conditioned air into the shoe through the supply port, bores, insole aperture and air channels located in the air diverter. The AC system is releasably connected to the shoe. A shoe may be retrofitted with the tubular members, supply port and insole aperture post-manufacture by drilling bores through the heel and insole.
