A rain boot and uniform footwear with an intelligent temperature-controlling air extractor and water-proofing and air-venting functions, includes: a boot upper layer (10), a middle cushion layer (11) and a boot lower layer (12), wherein a miniature air extractor (13) is provided at a position below an instep of the boot bottom layer (12), a magnetic levitation power switch (14), a temperature sensor (15) and a control main board (16) are also provided in the boot bottom layer (12), the temperature sensor (15) being electrically connected to an input end of the control main board (16) and transmitting a temperature sensing signal of the foot to the control main board (16), and an output end of the control main board (16) being electrically connected to the miniature air extractor (13) via the magnetic levitation power switch (14).

A shoe component includes a base structure which is substantially shaped so as to reproduce at least partially the sole of a foot of a user, the base structure having an upper surface which is designed to be directed toward the foot and a lower surface which is opposite the upper surface, the component comprising one or more through holes and one or more blind holes provided in the base structure. The one or more through holes are in communication with one or more of the one or more blind holes through one or more channels provided in the base structure.

This disclosure represents a novel article of footwear that has a built-in toe drying system. The footwear is preferably in the form of a sandal having a sole and a strap attached to opposite sides of the sole and fastened to the top of the sole near forefoot region. More specifically, the footwear has a pair of micro fans releasably mounted in openings disposed in the strap. One micro fan is connected to a duct integrated in strap and the other micro fan is connected to a duct positioned along the side of the sole. The airflow generated by the micro fans are directed towards respective connected ducts such that the airflow is expelled through holes to dry moisture and water on foot of a wearer of the footwear. The sole has a plurality of ripples on top surface thereof and the ripples facilitate drainage of water.

The present invention is directed toward an article of footwear effective to regulate the temperature of the feet of a wearer. In an embodiment, the article of footwear includes an upper and an insole with a thermal effect membrane. The thermal effect membrane contains a plurality of system-reactive components selectively engaged heat and/or moisture. In an embodiment, the printed coating includes a cooling agent, a phase change material, and a heat dissipation material. The bottom of the sole structure of the article of footwear further includes a multiple openings in the forefoot, midfoot, and hindfoot regions. The multiple openings promote airflow into the interior of the upper. In operation, the article of footwear is effective to delay/diminish the rise in skin temperature (compared to footwear lacking the membrane and/or openings), increasing wearer comfort.

Disclosed is a waterproof shoe with an improved ventilation mechanism, designed to circulate air from the outside environment through the shoe in order to provide convective cooling to a wearer's foot. In a desired embodiment, the shoe may incorporate a pump-ventilation mechanism which, coupled with airflow channels incorporated in the upper, acts to establish continuous substantially one-way airflow through the shoe in a heel-to-toe direction while a user walks.

A shoe has an air pump device comprising a bellows formed in a cavity in a heel area of the sole structure. The cavity has an average height of at least 4 mm and extends horizontally over most of the surface of the heel area, so that a support strip of the compressible material of the at least one intermediate layer remains between the cavity and the outside edges of the sole structure on the sides and at the heel, wherein the support strip extends vertically over the full height of the cavity and the average width of the support strip is not more than 20% of the maximum width of the heel area measured transversely to the walking direction. The compressible material has an average hardness between 30 and 55 Shore-A at least in the area of the support strip.

A sole structure for an article of footwear. The sole structure comprises a sole component; and an insole, the insole being mounted to the sole component so as to define a cavity within the sole structure, the insole comprising a resiliently deformable diaphragm element that is constructed and arranged to force air through the cavity when depressed.

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.

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.
