A slipper for drying between the toes of the user. The slipper includes a fan and warming element to dry the foot. The fan blows through air channels in the foot bed to dry between the toes. Separators and contours on the slipper separate the toes of the user to allow air to blow on the skin between the toes, drying the skin. The slipper includes a power switch to active the slipper. The slipper includes a power supply.

A forced-air footwear is presented and comprises a foot supporting portion including a sole with cavities therein covered with a foot-contacting layer, and a channel communicating between the cavities and the interior of the footwear to allow air flow between the cavities and the interior of the footwear; a foot covering portion, the foot covering portion including a valve allowing air passage therethrough in a single direction, the cavities including a compressed configuration, when supporting a weight of a wearer, and an expanded configuration when not supporting the weight of a wearer, the passage between the compressed configuration and the expanded configuration forcing an air movement of the air contained in the cavities, the valve blocking the air movement in one direction, wherein the compression of the cavities and the blocking action of the air by the valve is forcing air through the footwear.

An athletic shoe includes a first cleat, a second cleat, and a third cleat. The first cleat is configured to extend and retract relative to a front portion of the athletic shoe. The second cleat is configured to rotate relative to a bottom portion of the athletic shoe. The third cleat is configured to extend from and retract into the at least one second cleat.

A ventilation sole for footwear, the sole including: a communicating vent-hole through which the inside and outside of footwear communicate with each other to allow air to flow; and a valve selectively opening and closing the communicating vent-hole, wherein the valve includes: a housing module configured to have opposite ends being open such that a channel is provided therein to communicate with the communicating vent-hole; an open-close module configured with a first closing surface and a first through-hole; and a rotation module configured with a second closing surface and a second through-hole, and rotating to move a position of the second through-hole. Accordingly, a wearer can easily open and close the valve by rotating the rotation module according to the intention of the wearer, whereby air inside and outside the footwear can be circulated selectively and optimal foot conditions can be improved.

A breathable sole, including a midsole and an outsole; a bottom surface of the midsole has an air chamber, an air inlet channel and a single-way air outlet channel; the air chamber is provided at a heel position; the air inlet channel comprises a dispersed air-collecting channel and an air-guiding channel; the dispersed air-collecting channel is provided at the sole and is provided with air inlet holes; the air-guiding channel is connected with a rear position of the dispersed air-collecting channel and the air chamber; the single-way air outlet channel is a Tesla Valve which has an end connecting to a front position of the air chamber, and has another end provided with an air outlet hole penetrating the upper surface of midsole; the single-way air outlet channel imposes a higher resistance against air flowing from the air outlet hole to the air chamber.

A sole for footwear and footwear including the sole wherein the sole includes a first layer having a plurality of orifices passing through and configured to be connected to an upper of a footwear article and to form an inner environment of the footwear, and a second layer coupled to the first layer, having a plurality of chambers and one or more channels or passages fluidly connecting the orifices and chambers. The sole also includes a pressurization device in fluid communication with the channels or passages and is configured to increase the air pressure in the plurality of chambers and regulating valves in fluid communication with the channels or passages to regulate a pressure in the plurality of chambers.

An article of footwear includes an upper and a sole coupled to the upper. The article of footwear includes a vacuum pump assembly. The vacuum pump assembly includes a flexible bladder and a pump disposed in the sole and in fluid communication with the bladder. The pump removes air from the bladder to draw a vacuum within the bladder. The pump includes a plunger that activates the pump in response to the application of force against the sole. The bladder constricts and conforms the upper against the wearer's foot as the pump removes air from the bladder to generate the vacuum.
