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 footwear cooling system includes a main airflow tube and first and second secondary air flow tubes positioned in respective air inlets in the front of a shoe. The first and second secondary air flow tubes join the main air flow tube at respective acute angles at a junction positioned a selected distance behind the main air inlet. The portion of the main airflow tube in front of the junction and the first and second secondary air flow tubes each have a plurality of air ducts formed on their side surfaces. The main air flow tube is connected to a fan which pulls air in from the main and secondary air inlets and exhausts air out of the rear of the shoe.

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.

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 includes a shoe sole and a shoe main body. The shoe sole is configured to be connected to the shoe main body and forms an accommodating space with the shoe main body. The shoe sole includes a supporting member and a supporting insole. The supporting member is provided with a blowing device and a blowing channel. One end of the blowing channel is connected to the blowing device, and the other end is connected to the upper surface of the supporting member. The supporting insole includes an insole surface; an air hole is provided in the insole surface; one end of the air hole is configured to be communicated to the accommodating space; the supporting insole is arranged on the supporting member.

A footwear article having a vacuum release mechanism is disclosed. The vacuum release mechanism is configured to equalize pressure and release a vacuum created beneath a sole of the footwear article. The vacuum release mechanism mitigates undesired retention of the footwear article in high-viscosity materials such as mud or concrete. The vacuum release mechanism includes at least one sleeve fixedly secured within at least one fluid passageway formed in the sole, which fluidly connects an exterior environment to an interior of the footwear article. A replaceable check valve is removably disposed within the at least one sleeve. An installation and removal tool may be used to engage and disengage the check valve from the at least one sleeve.

A climate control system for a shoe is provided and includes a pumping assembly, a discharge-end assembly and a suction-end assembly. The pumping assembly is formed in a one-piece structure and includes a first layer structure, a second layer structure and a plurality of supporting structures located inside a chamber formed between the first layer structure and the second layer structure and integrally connected between the first layer structure and the second layer structure. When the pumping assembly is forced to be resiliently compressed, air inside the pumping assembly is driven to flow toward the discharge-end assembly and then flow out of the discharge-end assembly to an interior of the shoe through a plurality of ventilation openings. When the pumping assembly is released to resiliently recover, ambient air is driven to flow toward the pumping assembly through the suction-end assembly. Besides, a related shoe sole is also provided.
