  • 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 transpire .
  • Various attempts have been made to solve this problem.
  • 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.
  • a solution that has achieved substantial success is the one that foresees coating the inside of a perforated rubber sole with a microporous membrane, thus impermeable to water but permeable to air and sweat in the form of water vapour.
  • this solution also has some drawbacks.
  • the problem forming the bases of the present invention is therefore that of providing an aeration system for shoes that allows an effective and efficient exchange of air and vapour between inside and outside of the shoe.

  • Figure 12 represents a front side view of the insole of figure 11 according to the section XII-XI ⁇ .
  • 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 can of course also be made from leather or comprise a leather tread.
  • the hollow sole 1 comprises l 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 Ia.
  • 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.
  • a plurality of ramifications 6 project, in a substantially transversal direction, which, similarly to the main groove 5, extend up to the edge Ia.
  • the edge Ia of the sole 1 comprises transversal holes 7, which place the cavity 3 in fluid communication with the outside.
  • the valve means 8 typically consist of a one-way valve for shoes. This type of valve is conventional and basically consists of a small cylinder inside which a flap is placed that only opens if the air flow is towards the outside, whilst it does not allow the entry of air from the outside.
  • Said valve means 8 can also simply consist of a dividing wall or membrane made from microporous material (for example, GORETEX 1 ”) , which allows air and water to pass, but is waterproof.
  • An aeration device is housed in the sole 1 according to the invention.
  • Such an aeration device preferably comprises pumping means 9, typically a bellows pump, housed in the first cavity 2 of the sole 1.
  • pumping means 9 comprise a shell 10, formed from two half-shells 10a, 10b, and a distribution nozzle 11. The opening of the nozzle 11 is placed at the channel 4.

  • the shell 10 shall be made from polyurethane having the Shore A hardnesses outlined above .
  • the shell 10 houses an elastic core 12 inside of it.
  • the main function of such an elastic core 12 is to increase resistance to stepping and to act as a "shock absorber" . Indeed, it has been seen that the provision of a hollow pump without inner core at the heel leads to excessive yielding of the footbed at that point and consequently causes an irregular and not very comfortable gait. Moreover, if the hollow pump collapses, it is no longer able to recover its initial shape and the pumping function is thus ended.
  • the elastic core 12 can consist of conventional elastic means, like a spring. However, in the preferred embodiment shown in the drawings, such an elastic core comprises an elastic insert made from an elastomer, like for example polyethylene.
  • such an elastomer shall have a Shore D hardness of over 60, more preferably over 80, even more preferably over 90.
  • the elastomer used for the elastic core 12 shall have a Shore A hardness of between 15 and 30 r more preferably about 20.
  • an elastic core 12 is of a size, in particular a thickness, such as to create a gap between the core and the inner walls of the shell 10.
  • the shape of the elastic insert substantially follows that of the shell 10, but it has smaller dimensions so as to create the gap described above.
  • the elastic core is perforated on three sides, so that a network of small channels 13, 13', 13", 13"', 13"" is formed inside it.
  • the elastic core 12 itself forms a bellows pump that is associated in action with that of the shell 10.
  • the elastic core 12 and/or the shell 10 shall contain perfume.
  • a "compound" of the rubber/plastic material shall be made with the perfume, which shall thus be absorbed in the material and shall be released very gradually.
  • the perfume can be contained in microspheres arranged inside and/or outside the elastic core 12 or on the surface of the shell 10, so as to have an even longer-lasting release, mediated by the mechanical action (rubbing) and not just by the normal evaporation of the perfume.
  • the shell 10 preferably has substantially flat base surfaces 14, 14' and a side surface 15 that has sides with concave profile joined by rounded corners. This shape allows the side surface 15 to be stiffened, keeping a good flexibility of the base surfaces 14, 14' . In this way the bellows pump can easily carry out its pumping action without collapsing, not even partially, under the weight of the heel.
  • the shell 110 has the long sides with a rectilinear profile and the end portions 4 rounded.
  • the shell 10 can have the following dimensions: length about 6 cm, width about 4 cm, thickness about 2 cm.
  • the device of the invention allows the circulation of about 20 cc of air/vapour inside the shoe.
  • Such a volume shall decrease according to the bulk of the elastic core 12 arranged inside the shell 10, but it shall in any case be between 5 and 10 cc. It is clear that it shall be possible to vary the dimensions of the shell 10 according to requirements, for example according to the type of shoe or the size.

  • the bearing 18 shall be made from an elastomer in which holes or microholes shall be made to make it porous. With the described materials, the bearing 18 shall be permeable to air/vapour and shall contribute to the pump effect created by the pumping means 9 arranged at the heel.
  • the bearing 118 shall be made from rubber or another elastomer and shall comprise a perforated top surface 130 and a bottom surface from which a plurality of flexible flaps 131 project.
