A footwear article having a vacuum release mechanism is disclosed. The vacuum release mechanism equalizes pressure to release a vacuum created beneath the footwear article, thereby eliminating an undesired retention of the footwear article in high-viscosity materials such as mud or concrete. The vacuum release mechanism includes at least one check valve disposed in at least one fluid passageway formed in a sole of a footwear article. The at least one fluid passageway fluidly connects an exterior environment with an interior of the footwear article.

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.

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.

Describes are support elements for a sole of a shoe, in particular a sports shoe, a sole and a shoe with such a support element, as well as a method for the manufacture of a support element. As examples, the support element includes a first partial member formed of a first material, and a second partial member formed of a second material. The first partial member is mechanically joined to the second partial member in a connection region, wherein the connection region is configured to allow the first partial member to rotate or slide relative to the second partial member. The first partial member, the second partial member, and the connection region can be co-molded and joined together in a single fabricating step.

A shock-absorbing, waterproof, and breathable shoe sole is provided, including a midsole. The top of the midsole is provided with a concavity, and the bottom of the concavity is provided with multiple breathable grooves. The left and right side walls of the breathable grooves are provided with through holes connected to the outside. A gasket is adapted to be placed in the concavity, and the gasket is integrally formed from a support plate and a breathable waterproof cloth. The support plate is provided with multiple breathable holes aligned with the breathable grooves. The shoe sole of this application is provided with multiple breathable grooves, and the inner wall of the breathable grooves is provided with through holes that connect to the outside.

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.
