An insole with heat generating system is disclosed, which comprises an insole, a piezoelectric module disposed inside the insole and electrically connected with each other to form an electrical circuit, two flexible conductive strips having a first conductive copper piece and a second conductive copper piece disposed thereon, and at least one resistive heating chip. Wherein the piezoelectric module generates the electrical energy through stepping on the insole, and then turns into the heat energy through the resistive heating chip, thereby generating a temperature for the insole, so the insole with heat generating system can adjust the temperature appropriately, its safety is high, most importantly, the invention does not need to add the battery to generate heat.

An intelligent insole is provided. The intelligent insole includes an insole body, a pressure sensor, a temperature sensor, a humidity sensor and a signal collector. The pressure sensor, the temperature sensor and the humidity sensor are formed on the surface of the insole body, and the above sensors and the insole body are manufactured via the same 3D printing process. The pressure sensor senses the pressure signal from the insole body in contact with the foot. The temperature sensor and the humidity sensor respectively sense the temperature signal and the humidity signal of the insole body. The signal collector is respectively electrically connected to the pressure sensor, the temperature sensor and the humidity sensor to receive the pressure signal, the temperature signal and the humidity signal and then transmit the signals to a signal receiver via wireless transmission.

A method for distinguishing a foot motion of a user by placing a pedometer at a foot of a user includes the steps of collecting an accelerating data from an accelerometer in a real time manner; filtering the accelerating data via a smoothing filter and a Kalman filter; generating a step data that represents number of steps taken by the user in response to the accelerating data through the smoothing filter; generating an activity data that represents a foot motion of the user in response to the accelerating data through the Kalman filter; and combining the step data and the activity data to form a resulted data that distinguishes the foot motion with step count of the user.

Disclosed embodiments relate to a footwear system. The footwear system includes a shoe, a first insole, and a second insole. The first insole is a fitting insole having a first volume. It is positioned within the shoe during a fitting of a potential wearer of the shoe. The fitting insole is removed after the fitting is completed. The second insole has a volume substantially similar to the first volume. The second insole adapted for positioning within the shoe if the first insole demonstrates an appropriate fit. The second insole is self-customizable and further adapted to conform to the imprint of the sole of the potential wearer.

A customizeable footbed, a self-customizing footwear having a customizable footbed, and a method for customizing a footbed to conform to contours of a foot is provided. The customizable footbed may include a plurality of packets, each packet comprising an exterior membrane defining a chamber therein, and an interior filling within the chamber. The interior filling may be selected from a group consisting of two or more components of a curable material that chemically react upon mixing of the components to irreversibly form a solid or semi-solid resin or a gel. The plurality of packets may be configured to burst upon application of a pressure such that the interior fillings of the packets flow into and mix within the intermediate space.

A sock has a leg portion, a heel portion, an instep portion, a toe portion, and a pair of lateral metatarsal joint portions where the instep portion meets the toe portion. The sock has a first material thickness at the instep portion and the toe portion, and a second material thickness at at least one of the lateral metatarsal joint portions, wherein the second material thickness is less than the first material thickness.

The present invention relates to articles of manufacture having a formulation distributed therein, wherein the formulation comprises an active agent which manifests a desirable property when released from the articles of manufacture. The present invention also relates to methods for manufacturing these articles of manufacture, to vehicles for applying the formulation to these articles of manufacture, and to perception indicators indicating the presence and the amount of formulation comprising an active agent applied to an article of manufacture.

A shoe (A) provided with an internal side (LI) and an external side (LE) and comprising a sole (I), an intermediate sole (3) and a reinforcement insert (4) joined with the intermediate sole (3) and comprising at least one lateral wing (42,43) which is inclined and disposed on the internal side (LI) or the external side (LE) of the shoe (A).

A magnetic acupoint massage insole for conditioning chronic diseases includes a left insole and a right insole. The left insole includes a heel, a middle part and a head, and a magnet, a functional bump and an auxiliary bump are disposed on the left insole. The right insole comprises a heel, a middle part and a head, the right insole, and a magnet, a functional bump and an auxiliary bump are disposed on the right insole. The present invention has the effects of providing a better massage effect by the distribution of reasonably designed bump massage points together with the magnetic therapy effect provided by a magnet, stimulating the nerve endings of human body and organs, promoting user's blood circulation, and enhancing metabolism. In addition, the invention has a health care effect on a multiple of reflection zones, a high practicality, and a strong promotion effect.

A footwear-insole for modifying a user's gait configured to extend under a user's foot and provide greater than 0 to 5.0° dorsiflexion support and greater than 0 to 5.0° eversion support.
