A shoe has a heated insole with a battery-receiving portion. A battery is insertable into and removable from the battery-receiving portion of the shoe's insole while the insole is disposed within the shoe.

A temperature-adjustment shoe sole, including a supporting member. The supporting member is provided with an air guide channel. A semiconductor temperature control unit, wherein the semiconductor temperature control unit is arranged in the supporting member. The semiconductor temperature control unit has a first temperature control end and a second temperature control end. The first temperature control end of the semiconductor temperature control unit is in contact with an air fluid in an accommodating space to generate a first air fluid. The second temperature control end of the semiconductor temperature control unit is in contact with the air fluid in the accommodating space to generate a second air fluid.

A method and apparatus for generating thermal energy (heat) from human locomotion is proposed and used to provide heating of the user's footwear. The apparatus takes the form of a pair of flexible, liquid-filled chambers connected by an energy-generating tube. One chamber is located in the heel region of a footwear insole, with the other in the toe region, such that as a person walks, the liquid moves back and forth within the tube. This movement is used to also move an energy-producing element (either an electromagnetic arrangement or viscous liquid) back and forth within the tube and convert the captured human locomotion energy into thermal energy, thus warming the footwear.

A heated insole for a shoe has an insole body, a heating element, and a removable assembly. The insole body has a recess, and the heating element delivers heat to at least a portion of the insole body. The removable assembly is removable from and insertable into the recess of the insole body, and includes a battery and a control circuit that is configured to control heating of the heating element.

A battery for use with a heated insole has a cushion portion on top of the battery to provide comfort when the battery is disposed within the insole.

A shoe has a heated insole with a battery-receiving portion. A battery is insertable into and removable from the battery-receiving portion of the shoe's insole while the insole is disposed within the shoe.

An assembly for inclusion in a heated insole has a heating member and a frame. The frame has a connector that allows a person to couple a battery to and decouple the battery from the heating member.

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 cycling shoe system is basically includes an upper, a sole, a closure, an actuator, a communicator and a controller. The upper has a first portion, a second portion, and an opening between the first portion and the second portion. The sole is attached to the upper. The closure is coupled between the first portion and the second portion. The actuator is operatively coupled to the closure to adjust a relative position of the first portion and the second portion. The communicator is configured to receive at least one of bicycle information and user information. The controller is configured to control the actuator to adjust a tightening force applied by the closure to a target tightening force based on at least one of the bicycle information and the user information.
