Definitions

  • the present invention relates to the field of shoe and footwear constructions.
  • the heat and perspiration released by the foot causes several problems.
  • a wet and warm shoe interior is uncomfortable for the user to wear.
  • the perspiration released by the foot contains sodium chloride and urea, which can stain or discolor the outer surface of the shoe, degrading the expressive value of the shoe to the wearer.
  • the perspiration and heat around the foot creates an ideal environment for fungi and bacteria to thrive.
  • Fungi and bacteria consume dead skin cells, and produce waste that is the source of foot odor.
  • Fungi and bacteria convert the amino acid methionine to methanethiol which has a sulfuric smell.
  • foot perspiration, bacterial growth, and bacterial waste production all increase, causing odor to intensify.
  • a warm and moist shoe provides an ideal environment for foot disease, such as Athlete's foot, to thrive.
  • shoe ventilation to transfer heat and moisture away from the foot.
  • the theory behind shoe ventilation is to reduce the interior temperature and humidity of the shoe by transferring heat and foot perspiration generated by the foot away from the interior of the shoe. Since perspiration decreases with decreasing temperature, a decrease in the interior temperature of the shoe decreases the rate of perspiration around the foot.
  • the goal of shoe ventilation is to maintain an interior shoe temperature as close to the ambient air temperature as possible. By forcing ambient air around the foot and into the shoe cavity, heat and moisture generated by the foot is transferred away from the foot by the circulating air.
  • US 2008/229623 discloses a shoe air circulation system with a heel air pump and an air distribution pad under the foot.
  • the air distribution pad is shown in Fig.3 as a foam material; in Fig. 8 it is a structured polymer element.
  • US 2010/275466 discloses a shoe with a ventilated upper.
  • WO 2011/051320 discloses a shoe air circulation system with a heel air pump and an air distribution structure under the foot.
  • EP 0479183 discloses a shoe with a partition grid located under the shoe insole.
  • WO 2010/115737 discloses a shoe air circulation system with a heel air pump and an air distribution structure under the foot.
  • WO 2007/128671 discloses a shoe with a ventilated upper.
  • US 5353525 discloses a shoe with a heel air pump to inflate ankle supporting air pillows in the shoe upper.
  • DE 9016134U discloses a shoe with a porous middle layer in the upper.
  • a shoe with an air circulation system has a porous ventilated upper and a compressible pumping chamber in the heel which pumps cooling ambient air from an external air intake into a three dimensional mesh air distribution pad and out through the porous ventilated upper, providing cooling and reducing moisture in the cavity containing the wearer's foot.
  • the shoe with an air circulation system 10 includes an upper 20 and a sole 40.
  • the upper 20 and the sole 40 are positioned together to form the shoe 10 with an air circulation system.
  • the sole 40 and the upper 20 operate together to provide a ventilation system that circulates ambient air through the sole 40 and upper 20, cooling the interior cavity 12 of the shoe 10.
  • the upper 20 includes an outer layer 22, a porous middle layer 24, and an inner layer 26.
  • the inner layer 26 is adjacent to the interior cavity 12 of the shoe 10.
  • the outer layer 22 is adjacent to the ambient atmosphere 14.
  • the outer layer 22, porous middle layer 24, and inner layer 26 are positioned together to form a shoe upper 20.
  • the layers 22, 24, 26 may be positioned together by any means known in the art, including stitching or gluing with an adhesive. It should be understood that the upper 20 may include a greater number of layers, and may include additional components, for example shoe laces.
  • the outer layer 22 is constructed from leather.
  • the outer layer 22 may be constructed from canvas, synthetic leather, EVA, denim, wool, felt, or any other material or combination of materials known in the art.
  • the porous middle layer 24 is constructed from a porous material through which air can pass with little or no resistance.
  • the porous middle layer 24 is constructed from a synthetic mesh fabric material.
  • the porous middle layer 24 may be constructed from any material or combination of materials through which air can pass with little or no resistance.
  • the inner layer 26 is constructed from a soft lining.
  • the inner layer 26 is preferably provided with a plurality of perforations 28 to provide a fluid communication between the interior cavity 12 of shoe 10 and the porous middle layer 24 for venting the inside of the upper 10 to the middle layer 24.
  • a uniformly applied plurality of small pinpoint perforations is preferable, however, any appropriate number and size of perforations 28 can be used.
  • vent openings 30 are in the form of a plastic eyelet having desirable design or appearance features.
  • the upper may optionally include typical fastenings such as shoe lace holes 32 and shoe laces, or hook and loop fasteners, or buckles, or an elastic element.
  • the upper 20 is positioned on the sole 40.
  • the upper 20 is affixed to the sole 40.
  • the upper 20 is stitched directly to the sole 40. It is preferable that the upper 20 is attached directly to the sole 40 using a stitch.
  • the upper 20 may be affixed to the sole 40 by an adhesive, fastener, or any other means known in the art.
  • the sole 40 includes an outsole 42, a midsole 44, and an insole 46.
  • a thermoplastic shank 48 is provided in the center area of the shoe between the midsole 44 and insole 46.
  • the air circulation system includes a compressible pumping chamber 50 located in a heel area 52 of the shoe between the insole 46 and the midsole 44.
  • Pumping chamber 50 is a sealed chamber made from a resilient material.
  • the heel area 52 has a downwardly extending bump or bulge 53 which is comprised of a thin outsole 43 and thin, deformable portion 54 of the midsole 44, so that the pumping chamber 50 is periodically compressed by pressure applied thereto by a wearer walking in the shoe 10. This periodic compression pumps air through the air circulation system of shoe 10.
  • the thin deformable midsole portion 54 is desirably formed as a series of concentric ribs or rings as best illustrated in FIG. 5 , or it may be formed as another ribbed or perforated section to enhance the deformation of the portion 54 and the pumping of chamber 50.
  • Air is drawn into the air circulation system through an external air intake port 60 (which may include multiple port openings).
  • An inlet fluid passageway 62 connects the external air intake port 60 to the pumping chamber 50.
  • the external air intake port 60 is located at a level above a level of the pumping chamber 50 and the inlet fluid passageway 62 includes an upwardly extending snorkel 64 as seen in FIG. 10 .
  • Snorkel 64 is preferably positioned at a rear end 11 of the shoe 10, however, in alternative embodiments, one or more snorkels and/or intake ports may be located on the sides of the shoe or at the front of the shoe.
  • Air distribution pad 70 is a three dimensional spacer mesh fabric and is located in a cavity 71 in the insole 46 in a forefoot area of the shoe.
  • the upper surface of air distribution pad 70 is flush with the upper surface of insole 46.
  • the three dimensional spacer mesh air distribution pad is preferably formed of a polyester material and provides both comfort underfoot and a breathable material that distributes circulated air under the wearer's foot. Examples of three dimensional spacer mesh fabrics that may be used in the invention include fabrics such as those disclosed in U.S. Patents 5,385,036 ; 6,477,865 ; 6,630,414 ; 6,755,052 ; and 7,788,952 .
  • the spacer mesh fabric should have a compression set which is generally comparable to the compression set of the foam material used in the insole 46, and should have a sufficient durability to maintain usability over the expected life of the shoe without a significant deviation in thickness compared to the surrounding insole 46.
  • an inlet check valve 80 is located in the midsole 44 between the external air intake port 60 and the pumping chamber 50, and an outlet check valve 82 is located in each of the more outlet fluid passageways 66 between the pumping chamber 50 and the air distribution pad 70.
  • one or more peripherally and upwardly extending channels 90 are provided in the insole 46 and/or midsole 44 and extend from cavity 71 to provide fluid communication between the pumping chamber 50 and the porous middle layer 24 of the upper 20.
  • the peripherally and upwardly extending channels 90 may also or may alternately connect directly to the outlet fluid passageway 66 and extend through the insole and/or midsole and extend from cavity 71 to the perimeter thereof to provide fluid communication between the pumping chamber 50 and the porous middle layer 24 of the upper 20.
  • Pumping chamber 50 is being operable by periodic pressure applied thereto by a wearer walking in the shoe 10, which causes air to be drawn into the pumping chamber 50 from the external air intake port 60 through the inlet fluid passageway 62 and then expelled from the pumping chamber 50 through the outlet fluid passageway 68 to the air distribution pad 70, and from the upper 20 through the inner layer perforations 28 to the porous middle layer 24 of the upper 20 to the outer layer vent openings 30.
  • the present invention provides a shoe with an air circulation system which circulates cooling air underfoot and through a layer of the upper though the pumping action of the pumping chamber.
