A portable footwear air conditioning system allows a person to cool or warm their feet or another portion of their body. The system is removable can be transferred from one article of clothing to another. An air conditioning device forces air warmed or cooled, through a tube into a shoe. The air conditioning device utilizes a heat exchanger, fan or the like to alter the temperature of the air.

An insole which generates an air flow during use, which assists in cooling or warming the foot of a user is disclosed. In a first embodiment, air flow facilitated by said insole provides for convective heat transfer away from the plantar surface of the foot. The insole is intended for insertion into a shoe which is ventilated, preferably an athletic shoe with a ventilated upper. The bottom layer defines a plurality of ridges and channel lining portions which together define a plurality of air channels. The bottom layer defines a heel recess in which a heel pad is situated. In a second embodiment, an insole which collects, retains, and heats a user's foot is disclosed. Said insole further comprises a middle layer of thermal reflective material secured to and coextensive with a top layer and a bottom layer secured to said middle layer.

Articles of footwear and methods of making articles of footwear including one or more continuous threads wound around anchor points. The winding of the one or more continuous threads forms a thread pattern that imparts desired characteristics to components of the article of footwear. Thread lines of the thread pattern may be bonded together. In some embodiments, thread lines may be bonded with a bonding layer.

A ventilation apparatus including at least one flexible energy storage device (FESD), a switching unit, a pump, and a fluid diffuser is provided. The FESD flexibly conforms to varying contours of footwear. The FESD positioned at one or more locations of the footwear supplies electrical energy to the pump via the switching unit. The switching unit in communication with the FESD and the pump selectively changes modes of operation of the pump. The pump attached to the footwear pumps fluid into and exhausts fluid from a cavity of the footwear. A feed pipe of the fluid diffuser connected to the pump, within the cavity of the footwear, transfers the fluid pumped from the pump to the cavity of the footwear during a pump mode and transfers the fluid in the cavity of the footwear to an ambient environment external to the footwear during an exhaust mode for ventilating the footwear.

A foot is configured to map location and size of the ulcerations to treated at the bottom of the foot. First and intermediate insoles are made from including semi-compressed felt. A third sole serving as the base of the device is made from including, but not limited to EVA. A cavity with beveled edges in the first insole is configured to match the location and size of the ulcerations. The first insole, the intermediate insole and the foot with ulcerations are placed in a compression sock which is equipped with a zipper and is detachably attached on the top surface of the third sole. The cavity channels the drainage or extrude from the ulcerations to the intermediate in sole where it is absorbed. The zipper provides comfort to the patient to put on and take off the compression sock with any disturbance to the ulcerations .The compression sock enhances the blood flow in the foot which prompts efficient and quick healing of the ulcerations or chronic wounds.

An intelligent fabric includes: a base layer provided with vent holes and a thermal insulation layer arranged on the base layer and moved relative to the base layer; a temperature sensor configured to detect temperature information; and a controller connected to the temperature sensor and the thermal insulation layer, and configured to control the thermal insulation layer to be moved relative to the base layer in accordance with the temperature information detected by the temperature sensor, to switch the thermal insulation layer between a state where the thermal insulation layer covers the vent holes completely and a state where the thermal insulation layer does not cover the vent holes, or among the above two states and a state where the thermal insulation layer covers a portion of the vent holes.

A disclosed shoe may include a non-weight bearing portion of the shoe. The shoe may also include a packet which may include particles of microporous desiccant material enclosed in the non-weight bearing portion of the shoe. The microporous desiccant material may absorb moisture, water, and odor within the shoe.

An article of footwear may include an insert configured to receive a foot of a wearer. The insert may consist essentially of a casing configured to at least partially enclose a foot of a wearer and including a casing material and a high heat capacity material. The article of footwear may also include an outer assembly configured to receive the foot of the wearer when the foot is received within the insert.
