Definitions

  • the present invention relates to ventilated footwear. More specifically, the present invention relates to footwear having openings in the arch area of the upper, a waterproof and breathable membrane across said openings, and a compressible insole with openings in the top side in communication with channels on the underside which are in communication with the openings in the arch area of the upper for ventilating the interior of a footwear.
  • An article of footwear comprising:
  • an upper part coupled to said lower part and shaped to receive a foot of a wearer, said upper part having an arch portion with a plurality of openings providing communication between the outside of the upper part and the interior of the upper part,
  • FIG. 1 is a perspective view of a preferred embodiment of the ventilated footwear according to the present invention.
  • FIG. 2 is an exploded view of the arch portion of the footwear.
  • FIG. 3 is an under view of the insole.
  • FIG. 4 is a cross-sectional view of a insole operatively inserted within a footwear.
  • FIG. 5 is a cross-longitudinal view of a channel communicating with the arch portion of the insole of FIG. 3 taken along the line V-V.
  • FIG. 6 is a cross-view of the insole of FIG. 3 taken along the line VI-VI.
  • FIG. 7 is a cross-view of the insole of FIG. 3 taken along the line VII-VII.
  • ventilated footwear ( 10 ) comprises a lower part ( 12 ) incorporating a sole ( 14 ), an upper part ( 16 ) coupled to the lower part ( 12 ) and shaped to receive a foot of a wearer.
  • the upper part ( 16 ) may be of any type of footwear (an athletic shoe, a work boot, a hiking boot, etc.) and may be of any type of material (canvas, leather, synthetic leather, vinyl, plastic, etc.). These materials have a wide range of breathability, but often the construction of the upper part ( 16 ), particularly because of the use of adhesives, substantially reduce the breathability of the upper part ( 16 ).
  • the upper part ( 16 ) may also have a lining ( 20 ) to provide a comfortable interior surface to be in contact with the foot and/or sock of the wearer.
  • linings are typically woven or non-woven textiles, and may have wicking properties.
  • the upper part ( 16 ) may be treated with oils, silicone or the like to provide water resistant or water proof properties. Of course, such treatments usually interfere with the breathability of the material comprising the upper part. Waterproof and breathable membranes such as that sold under the GORE-TEX trademark are often also used on the inside of the upper part of footwear to provide water resistance with the intention of minimizing the interference with the breathability of the material comprising the upper part ( 16 ).
  • the upper part ( 16 ) has an arch portion ( 18 ) located on the medial side of the footwear.
  • a plurality of openings ( 24 ) are located in the arch portion ( 18 ) of the upper part ( 16 ) of the footwear on the outside ( 22 ) thereof.
  • the openings ( 24 ) may be arranged in almost any configuration to satisfy the aesthetic requirements of the design of the footwear. Typically, the openings ( 24 ) will be in the order of a few mm in diameter.
  • a waterproof, breathable membrane ( 26 ) larger than the area of the openings ( 24 ) is secured to the upper part ( 16 ) across the openings.
  • the membrane ( 26 ) is preferably made of material such as the material known by the trademark GORE-TEX or another equivalent material. Such material allows air and water vapor to move across it, but does not allow water in liquid form to move across it.
  • membrane ( 26 ) is secured to the interior ( 20 ) of the upper part ( 16 ) and may be secured between the upper part and any interior lining, although is contemplated that it may be secured to the exterior of the upper part ( 16 ).
  • the membrane ( 26 ) may be secured by adhesive about the periphery or adhesive tape or stitched, although stitching may require the stitch holes to be sealed to ensure that the stitch holes do not admit water to the interior of the footwear.
  • the membrane may also be combined with a lining material which may be particularly advantageous when the membrane is to be disposed on the interior of the upper part with no liner between it and the foot (or sock over the foot) of the wearer.
  • the membrane of the preferred embodiment is generally a half circle in shape as shown in FIG. 2.
  • An insole ( 28 ) is preferably disposed into the footwear and it is preferably made of a resilient and compressible material, such as polyurethane, although EVA and other such materials may be used.
  • the insole ( 28 ) is shaped to fit within the upper part and is contoured to provide a comfortable footbed for the foot of the wearer. Insoles of this type are well known, an example of one such footbed can be found in U.S. Pat. No. Des. 290,423.
  • the contouring of the insole includes an arch portion ( 30 ) which extends upwardly (see FIG. 4) to provide support and comfort for the medial arch of the foot of the wearer.
  • a plurality of openings ( 40 ) are provided substantially vertically through the thickness of the insole ( 28 ).
  • the greater the number of openings ( 40 ) and the larger the openings ( 40 ) the greater degree of ventilation may be provided by the invention.
  • the size and shape of the openings ( 40 ) are limited only to the extent that the support and comfort function of the insole ( 28 ) would be compromised.
  • the openings ( 40 ) may be arranged in a variety of configurations, again with consideration of the support and comfort function of the insole in mind, and with consideration of the structure of the bottom side of the insole as discussed below.
  • a lining material ( 32 ) preferably made of a quilted textile such as the one known by the trademark CAMBRELLE is secured to the top surface in order to provide a comfortable surface for the foot of the wearer as well as air circulation and wicking properties.
  • An alternative lining material such as kidskin leather may also be employed.
  • the openings ( 40 ) may not have to extend through the lining material; however, in the case where kidskin leather is employed, it is desirable that the openings ( 40 ) pass through the lining material in order to maximize breathability.
  • the bottom of the insole is provided with a plurality of substantially horizontal grooves or channels ( 36 ) in register with the substantially vertical openings ( 40 ) through the thickness of the insole ( 28 ) such that the channels ( 36 ) are in communication with the openings ( 40 ).
  • the channels may be arranged in a variety of configurations with consideration of the location of the substantially vertical openings ( 40 ) through the thickness of the insole ( 28 ) as well as the support and comfort function of the insole ( 28 ) in mind.
  • the durometer of the insole ( 28 ) material, the thickness of the insole ( 28 ), and the depth of the channels ( 36 ) should be selected such that when a person walks or runs, the insole ( 28 ) should substantially compress to provide a pumping action but allow the channels ( 36 ) to remain open in order to permit adequate air circulation.
  • the weight of the wearer must, of course be taken into account in making such selections. Such selections are within the abilities of one of ordinary skill in the art and the ranges are not particularly different than that generally presently employed.
  • the plurality of channels ( 36 ) are arranged to be in communication with a plurality of channels ( 42 ) which extend to the upwardly extending arch portion ( 30 ) of the insole (see FIG. 4). These channels ( 42 ) are located so as to be in register with the openings ( 24 ) in the upper part.
  • the channels ( 42 ) extending to the upwardly extending arch portion ( 30 ) of the insole may terminate in a cavity located in the upwardly extending arch portion ( 30 ) underside of the insole ( 28 ) and that cavity would be in communication the plurality of the openings ( 24 ) in the upper part.
  • the insole ( 28 ) compresses resulting in air being pumped through the channels ( 36 ) ( 42 ) and through the openings ( 24 ) in the upper part.
  • the insole ( 28 ) expands to its uncompressed state, low pressure is created within the interior of the upper part and air is thereby drawn into the upper part through the openings ( 24 ) therein, through the channels ( 36 ) ( 42 ).
  • the openings ( 40 ) through the thickness of the insole permit the circulation of air to extend to that portion of the interior of the footwear above the insole and closer to the foot of the wearer.
  • the present invention may be provided to a footwear manufacturer or even a shoe repair facility as a kit comprising a template for the openings ( 24 ) in the upper part ( 16 ), an insole ( 28 ) constructed according to the invention and a membrane ( 26 ) with adhesive means.
  • the insole can be sold separately for insertion in any kind of shoe that is provided with holes but not necessarily provided with a membrane.
  • such a combination would provide ventilation but not waterproof capabilities, unless the shoe is provided with a waterproof membrane across the holes.
  • the present invention may be employed in wide variety of footwear types employing a wide variety of materials. The overall cost of adding the present invention to footwear is low compared to other ventilation schemes.
  • the present invention relates to a ventilated footwear ( 10 ) such as, regular shoes, athletic shoes, outdoor shoes, casual shoes, ski boots and fishing boots, where there is a need to ventilate the foot of a wearer, and is meant to include, but is not limited to: all categories of children's, women's and men's footwear; basketball, football, soccer, tennis, golf, bicycle shoes; skates (ice or inline); cowboy boots; work boots and shoes; military boots and shoes; nurse's, doctor's and other medical personnel's shoes.
  • the holes on the upper part of the shoe could be placed anywhere else on the shoe with appropriate conduits between the holes and the channels of the insole, and such a modification falls within the skill of a person versed in this field.
  • the waterproof membrane can be located on the outside of the shoe or on the inside of the shoe, as long as the membrane is properly protected from accidental rupture, which would remove the waterproof properties of the membrane.
