  • Patent number: 6079123
    Abstract: The present invention is a self-ventilating insert for footwear with a wedge-shape pumping chamber located in the heel of the footwear. The pumping chamber can displace an air volume of at least about 44 cubic centimeters plus 3 times the U.S. men's footwear size. The pumping chamber has convex side and rear walls that fold together as the pumping chamber collapses. Maximum air circulation is achieved as the upper and lower surfaces of the pumping chamber come into full contact with each other. In a preferred embodiment, the length of the pumping chamber is between 30% and 60% of the length of the sole. The internal air duct, in a preferred embodiment, has a thin, wide cross-section with a plurality of tubes that resist kinking and pinching action near the flex zone of the footwear.

  • Patent number: 6006447
    Abstract: The present invention discloses a device for a shoe insole having multiple layers which form an air circulation system. A first layer is a fabric-like covering; a non-deformable second and deformable third layers forming together a layer with a cavity therein having offset apertures therein communicating by means of the cavity positioned underneath the fabric-like covering; a fourth layer made of foam rubber like material that deflates under the user's weight and re-expands when not under the user's weight; a bottom layer being a stiffer layer that forms a recess for receiving the other layers. A first and second exhaust conduit is formed in a side extension area for outward passage of stale air. The layers are joined to each other and the device is then inserted into the shoe of the user. The weight of the user is alternatively placed on and removed from the insole while walking or running. When the weight of the user is on the insole it compresses and stale air is forced out the exhaust conduit.

The air pumping device is detachable from the shoe so that it can be cleaned to remove dirts or alien objects that may block the air flow path. The air pumping device is located beneath the forepart of a foot wearing the shoe. When the user makes a step forward, an air bag is compressed at the instant the forepart of the foot is bent to lift the heel off the ground, thereby generating an air pumping action. When the forepart of the foot stretches straight again, the air bag restores to its original shape, thereby generating an air sucking action. As the user keeps moving, the air pumping device will pump air successively from the ambient atmosphere into the interior of the shoe. The air flow direction may be reversed so as to pump air inside the shoe out to the ambient atmosphere.

  • Patent number: 5400526
    Abstract: A sole for an article of footwear includes a heel area, an arch area, and a ball area, each defined on the top surface and corresponding to the respective areas of the foot. Each of the areas has a plurality of bulbous protrusions extending upwardly to contact the respective areas of the foot. A toe area is also defined on the top surface including a plurality of cavities in anatomical relation to the toes of the foot. The sole also has an air passage disposed between the top surface of the sole and the bottom surface of the sole. A plurality of upwardly extending sections connect the air passage to the top surface of the sole. The upwardly extending sections are disposed about the top of the sole between the bulbous protrusions and communicate ambient air surrounding the sole with ambient air above the top surface of the sole through repeated compression and expansion of the air passage.

  • Patent number: 5357689
    Abstract: A footwear ventilation system including the use of ventilation openings and integrally connected flap members. The invention includes the use of vent openings cut out of the side of a shoe. The vent openings may be of any shape to allow sufficient air flow therethrough. Around the periphery of each vent opening and the shoe, extends a perpendicularly oriented male track. A flap is integrally hinged to one side of the vent opening and has a integrally connected female track extending around the periphery of it. To close the vents, the female track of the flap is pushed onto the male track of the opening thereby facilitating a tight seal. When it is desired that the shoe be ventilated, the flap, being hinged to one edge of the opening, is pulled away from the opening, thereby disengaging the male and female tracks. In one embodiment of the invention, the flap or flaps, while integrally hinged to the shoe adjacent an opening, can be attached directly to the shoe.

  • Patent number: 5333397
    Abstract: An insole for ventilating shoes or boots comprising an air intake passage, an inflatable elastic bladder, an air exhaust passage, a ventilating capillary, and valve means. The bladder is formed along the peripheral area of the heel portion of the insole. Periodic application and release of pressure to the bladder causes air to flow out of the ventilating capillaries, thus cooling and drying the foot.

  • Patent number: 5295312
    Abstract: A ventilated boot or shoe is described wherein the boot or shoe is of conventional design having a sole, an upper portion, a toe, a heel, and instep portion, and sides forming an open top. Within the shoe, a spongy open-celled compressible insole is provided which has a pair of channels at each side entering the insole at the instep and at the heel portions. An impervious layer is sandwiched between upper and lower layers of spongy material to form said insole and an impervious material further forms the sides thereof. Ventilation pipes are provided which extend downwardly from the open top of the boot or shoe along the sides thereof and which form elbows at the lower end which enter the channels. As the wearer walks, the insole is compressed expelling air trapped in the open cells thereof and as pressure on the insole eases, the resilient insole expands drawing air through the ventilation tubes thereinto.
