Shoe sole that allows breathability of the foot

摘要

The present invention concerns the footwear sector and more specifically it concerns a sole obtainable through compression or injection moulding that allows breathability of the wearer's foot thanks to the combined action of a series of technical elements such as cylindrical stems with relative caps of underlying air chambers shaped like truncated cones and compression distribution devices all located underneath an alternating series of holes moulded on the sole.

主权项

1. An article comprising:
a shoe sole having a first plurality of holes and a second plurality of holes arranged in alternating relation with said first plurality of holes, each of said first plurality of holes having an opening at an upper surface of said shoe sole, each of said second plurality of holes having an opening at said upper surface of said shoe sole, said shoe sole having a cylindrical stem positioned in each of said first plurality of holes, said cylindrical stem having a cap at an upper end thereof, said cap positioned adjacent the opening of said first plurality of holes, each of said first plurality of holes defining a chamber of a truncated cone shape, said shoe sole having a plurality of dome-shaped cavities at a lower surface thereof, said chamber communicating with the dome-shaped cavity through a ventilation channel formed within said shoe sole, each of said second plurality of holes having a compression distribution protrusion formed thereon, said compression distribution protrusion having an upper surface adjacent the opening of the second plurality of holes, said cap being movable downwardly so as to close the opening of said first plurality of holes such that air in said chamber is discharged outwardly of said shoe sole through the dome-shaped cavity.
