A system, recharge apparatus, and method includes transmit coils positioned in a pattern to allow at least one of the transmit coils to establish a wireless link with a receive coil positioned in proximity of the recharge apparatus. A power source is coupled to the transmit coils and configured to selectively energize ones of the transmit coils to transfer power to the receive coil. An energy efficiency detection circuit is configured to detect an electrical response of each one of the transmit coils when energized by the power source, the electrical response indicative of an energy efficiency between the one of the transmit coils and the receive coil. The power source selectively energizes ones of the transmit coils, selected according to a statistical analysis of an historical record and the electrical response indicative of the energy efficiency meeting a minimum efficiency criterion for energy transfer to the receive coil.

A circulation therapy assembly includes a pair of boots that is each of the boots worn on one of a pair of legs. Each of the boots is comprised of a thermally insulating material and each of the boots has a height of at least 55.0 cm. Thus, each of the boots extends above a knee on the legs when the boots are worn. A pair of inserts is provided and each of the inserts is removably positioned within an associated one of the boots. Each of the inserts surrounds the associated leg and a corresponding foot when the boots are worn. Moreover, each of the inserts is comprised of a thermally conductive material. A pair of heating units is each coupled to an associated one of the inserts and each of the heating units heats the associated insert when the heating units is turned on. In this way each of the heating units heats the associated leg when the boots are worn thereby enhancing blood circulation in the associated leg.

A shoe, and a method for tightening such a shoe, in particular to a sports shoe, having a sole and a shoe upper, wherein the shoe upper has a first material section, which at least partially extends around the foot of the wearer of the shoe. To enable the tightening of the shoe on the foot of the wearer in a comfortable manner, a second material section is arranged on the outside of the first material section, in which the second material section at least partially covers the first material section, wherein the second material section is a plastic material having a shape memory effect.

A system for measuring and controlling foot temperature. The system comprises a heating or cooling device including one or more sealed fluidic pathways having a cooling or heating fluid therein and disposed in or on an article of footwear or a sock. A pumping device coupled to the heating or cooling device is configured to circulate the fluid in the one or more sealed fluidic pathways. A heat exchanger coupled to the heating or cooling device is configured to remove or add heat from or to the fluid in the one or more sealed fluidic pathways. A controller coupled to the pumping device and the heat exchanger is configured to control the pumping device and the heat exchanger to cool or heat a foot located inside the article of footwear or the sock.

Linear movement of a heel strike sequence for a shoe insole can be converted into rotational movement. This rotational movement can cause rotation of an interior of a generator. Rotation of this interior of the generator can cause an electricity to be generated and outputted. The generator can be considered a source of damping, so at the start of the heel strike sequence the generator can be non-engaged. After some time, the generator can be engaged and in turn rotate. This can allow for standing inertia to be more quickly overcome.

Articles of clothing, such as thermally conductive gloves, are provided. In some embodiments, a glove includes a fabric, a battery, and a fibrous material. The fabric battery may be electrically coupled to the material such that the material becomes thermally conductive when coupled to the battery, and loses its thermal conductivity when no longer coupled to the battery. In some embodiments, the battery couples to the fibrous material via a magnetic attraction.

An insole for controlling and adjusting the temperature of the foot. The insole includes a first heat conductive layer made of fabric, a second heat insulating layer comprising a Peltier cell. The Peltier cell includes a first surface and has a predetermined polarity such that, when the Peltier cell is on, the first surface is heated or cooled. A third heat dissipating layer includes an accelerometer and a logic control unit connected to the accelerometer and to the Peltier cell. The insole further includes a first flexible printed circuit configured to measure the temperature of the foot, through at least a first temperature sensor and the temperature of the first surface of the Peltier cell, through a further first temperature sensor.

A massaging boot assembly for massaging a foot includes a boot that may be worn on a foot. A massage unit is coupled to the boot and the massage unit selectively massages the foot when the boot is worn. The massage unit is selectively turned on and off. A heating unit is coupled to the boot such that the heating unit is in thermal communication with the boot. The heating unit is selectively turned on to selectively heat the foot thereby enhancing therapeutic relief of the foot.

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.

A wearable step-counting shoe includes a shoe body and a pedometer. The shoe body includes a shoe sole having opposite inner and outer sides, and a groove surface defining amounting groove. The pedometer is removably disposed in the mounting groove and includes a pedometer body having opposite first and second faces and configured to detect and record the number of steps taken by a user, and a screen disposed on the second face and configured to display the detected number of steps. An engaging unit is provided to fix the pedometer on the shoe body, and includes a first engaging portion provided on the groove surface, and a second engaging portion provided on the pedometer and releasably engageable with the first engaging portion.
