A shoe, and production methods for such a shoe, having a single-piece sole construction, in which efficient air circulation in the shoe and thereby directly on the foot of the user of the shoe is made possible with every step of the walking movement of the user.

A temperature modifying system for footwear having an air diverter positioned on top of the rear portion of the shoe insole, bores passing from an insole aperture beneath the air diverter to a supply port, and an AC system adapted to deliver conditioned air into the shoe through the supply port, bores, insole aperture and air channels located in the air diverter. The AC system is releasably connected to the shoe. A shoe may be retrofitted with the tubular members, supply port and insole aperture post-manufacture by drilling bores through the heel and insole.

The invention discloses a pair of sports shoes comprising a shoes body, a pressure generating device, a humidity sensor, a controller and a switch valve. A shoes chamber is provided at the heel of the shoes body, and the pressure generating device is arranged in the groove chamber. The upper work end of the pressure generating device is in contact with the lower surface of the insole of the shoes body; the humidity sensor is setted at the upper surface of the insole of the shoes body; the humidity sensor, the controller and the switch valve are electrically connected in turn, and the pressure generating device supplies power to the humidity sensor, the controller, and the switch valve, respectively; the controller controls the pressure generating device to stop or start energizing the solenoid valve tongue of the switch valve to close or conduct the gas passage.

A ventilation apparatus including a pump, a switching unit, and a fluid diffuser is provided. The pump attached to the footwear pumps fluid into and exhausts fluid from a cavity of the footwear. The switching unit in communication with the pump selectively changes modes of operation of the pump. The fluid diffuser connected to the pump within the cavity of the footwear includes a feed pipe for transferring the fluid pumped from the pump to the cavity of the footwear during a pump mode of operation and to transfer the fluid in the cavity of the footwear to an ambient environment external to the footwear during an exhaust mode of operation, for ventilating the footwear. In one or more embodiments, the fluid diffuser includes a diffusing member with one or more openings and/or a fluid distribution channel member for transferring the fluid to and from the cavity of the footwear.

A shoe has an air pump device for blowing air into the interior of a shoe comprising a bellows formed in the sole structure and surrounding a cavity, an intake channel for transporting air from an intake opening into the bellows, an air supply device formed in the sole structure for forwarding air from the bellows into the interior of the shoe, and a V-shaped or U-shaped spring element which clasps the bellows. An upper leg of the spring element comprises an upper pressure plate arranged above the bellows and below an insole of the sole structure, and a lower leg comprises a lower pressure plate arranged under the bellows and above an outsole layer, so that a connecting section that connects the two legs is arranged beside the bellows in the sole structure. The air pump device is arranged in such manner that when the sole structure is placed under load during a walking movement, the spring element is deformed elastically by pressing the pressure plates together, wherein the deformation takes place substantially at or close to the connecting section, so that the pressure plates substantially keep their shape, and the bellows is compressed.

A sole for aerated footwear having an elongate body with a lower surface, a device attached to the body, and an operating member, arranged to move away from and towards the body in a direction transverse to the longitudinal extent of the body as the sole bends to disengage and unbends to engage a floor, for operating the device. The device is attached to the body, engageable with the operating member, and is expandable from, or further away from, the lower surface of the body, upon movement of the operating member away from the body.

A shoe has a sole structure (3) and an air pump device for blowing air into the shoe interior space (14). The air pump device comprises a bellows formed in a cavity (10) in a heel area of the sole structure (3), an intake channel coupled to the bellows for transporting air to the bellows from an intake opening, and an air supply device coupled to the bellows for forwarding air from the bellows into the shoe interior space (14). The sole structure (3) has a multilayer structure at least in the heel area, which comprises at least one cover layer (7) with a layer made from a bending stiff material arranged over the cavity (10), at least one intermediate layer (6) of a compressible material that includes the cavity (10), and at least one outsole layer (5) arranged below the cavity (10). The layer of bending stiff material forms a bending stiff plate (8) that overlaps the cavity (10). The cavity (10) 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 (16) of the compressible material of the at least one intermediate layer (6) remains between the cavity (10) and the outside edges of the sole structure (3) on the sides and at the heel, wherein the support strip (16) extends vertically over the full height of the cavity (10) 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 (16).
