Abstract

A self-ventilating shoe assembly including an upper having an outer layer, a porous middle layer, and an inner layer; and a sole including an outsole; is provided with one or more passageways or chambers connecting between the outsole and the porous middle layer of the upper. One or more external vent openings are in fluid communication with the one or more passageways or chambers. Cooling ambient air is moved by convection and by a pumping action from the external vent openings through the passageways or chambers up through the porous middle layer of the upper, and optionally, the insole, providing cooling and reducing moisture in the cavity containing the wearer's foot.

Claims (15)

1. A self-ventilating shoe assembly, comprising:

an upper having an outer layer, a porous middle layer formed of a porous material, and an inner layer;

a sole including an outsole having one or more passageways provided between an upper surface of said outsole and said porous middle layer of said upper, and having one or more external vent openings in fluid communication with said one or more passageways, said vent openings providing continuous fluid communication both into and out of said one or more passageways.

2. The self-ventilating shoe assembly of claim 1 , wherein said upper is provided with one or more outer perforations for venting said porous middle layer.

3. The self-ventilating shoe assembly of claim 1 , wherein said one or more passageways are in fluid communication with said porous middle layer of said upper between said outsole and a midsole or an insole.

4. The self-ventilating shoe assembly of claim 3 , further comprising a porous insole, said porous insole being positioned above said outsole, and being in fluid communication with said passageways.

5. The self-ventilating shoe assembly of claim 1 , wherein said one or more external vent openings are deformable by compression causing at least partial closure of said one or more external vent openings and further causing air to be forced from said one or more passageways through said porous middle layer of said upper.

6. The self-ventilating shoe assembly of claim 1 , wherein said one or more passageways extend laterally from said one or more external vent openings.

7. The self-ventilating shoe assembly of claim 1 , further comprising one or more channels defined by one or more of an insole, a resilient midsole, and said outsole.

8. A self-ventilating shoe assembly, comprising:

an upper having an outer layer, a porous middle layer formed of a porous material, and an inner layer;

a sole including an outsole having one or more passageways provided between an upper surface of said outsole and said porous middle layer of said upper, and having one or more external vent openings in fluid communication with said one or more passageways said vent openings providing continuous fluid communication both into and out of said one or more passageways;

a porous insole, said porous insole being positioned above said outsole, and being in fluid communication with said passageways; and

one or more outer perforations for venting said porous middle layer.

9. The self-ventilating shoe assembly of claim 8 , wherein said porous material comprises a synthetic mesh.
