Aeration system and device for shoes

a technology of aeration system and shoe, which is applied in the field of aeration system for shoes, can solve the problems of not allowing sweat to transpire, increasing the problem of excessive sweating, and small amount of air exchange, so as to promote the evaporation of sweat, reduce the risk of injury, and improve the grip on the ground

Problems solved by technology

The problem of excessive sweating has become more serious with the appearance of the rubber sole replacing the leather sole.
The rubber sole, indeed, whilst being advantageous in terms of both heat insulation and water-proofing of the foot and the possibility of modelling the tread to make it grip better on the ground, is nevertheless impermeable to air and does not allow sweat to transpire.
For example, hollow soles have been provided comprising outside release valves, but the amount of air exchanged is small and therefore does not allow effective aeration of the foot.
However, this solution also has some drawbacks.
Moreover, after a few uses the micropores can be blocked by dust and dirt and therefore are no longer able to carry out their aeration function.

Embodiment Construction

[0031]With reference to the figures, the aeration system being the object of the present invention shall now be described.

[0032]The aeration system of the invention comprises a hollow sole 1, typically but not exclusively a hollow sole made from rubber or another synthetic material. The sole may of course also be made from leather or comprise a leather tread.

[0033]The hollow sole 1 comprises a first cavity 2, formed substantially at the heel area, and a second cavity 3, positioned substantially at the sole of the foot and defined by an edge 1a. Said cavities 2, 3 are open on top, i.e. at the inside of the shoe. The first cavity 2 and the second cavity 3 are in fluid communication through a channel 4 that is formed in the thickness of the sole and that continues, at the second cavity 3, in a groove 5. To the right and left of the groove 5, a plurality of ramifications 6 project, in a substantially transversal direction, which, similarly to the main groove 5, extend up to the edge 1a....

Abstract

The present invention concerns an aeration system for shoes comprising an aeration device, specifically pumping means like a bellows pump, which constitutes a further object of the invention.More specifically, the present invention concerns an aeration system for shoes, comprising a hollow sole (1) having an aeration device in fluid communication both with the inside of the shoe and with the outside, at least one first and a second cavity (2, 3) being formed inside said hollow sole (1), pumping means (9) being housed in said at least one first cavity (2), wherein said pumping means (9) comprise a shell (10) and a distribution nozzle (11), a flexible core (12) being housed inside said shell (10), and a pad (18) is housed in said second cavity (3).

Description

FIELD OF THE INVENTION[0001]The present invention concerns an aeration system for shoes comprising an aeration device, specifically pumping means like a bellows pump, which constitutes a further object of the invention.BACKGROUND ART[0002]Both hygienic and medical reasons dictate the importance of keeping the foot dry and well aerated. Good aeration, as well as dissipating bad smells, promotes the evaporation of the sweat that inevitably forms, above all in hot weather or during physical effort. The sole of the foot is indeed one of the parts of the human body where the sweat glands are most concentrated. The problem of excessive sweating has become more serious with the appearance of the rubber sole replacing the leather sole. The rubber sole, indeed, whilst being advantageous in terms of both heat insulation and water-proofing of the foot and the possibility of modelling the tread to make it grip better on the ground, is nevertheless impermeable to air and does not allow sweat to ...
