Definitions

• This invention concerns the footwear field in general and in particular an internally aerated shoe.
• a shoe in particular with a rubber or similar sole but not exclusively, must, in order to be sensible and comfortable, ensure a correct exchange of heat and vapour between the internal and external areas without in any way compromising its impermeable nature.
• the main objective of this invention is to avoid the known technical drawbacks with a shoe having a sole, which is impermeable towards the outside and equipped with a system for forced ventilation of the foot in reaction to the walking movement to ensure the best possible micro-climate inside the footwear.
• Fig. 1 shows a longitudinal section of a sole according to the invention with a separated sock-lining
• Fig. 2 shows a plan view of the base component of the sole in Fig. 1 ;
• Fig. 3 shows a cross section of the shoe with the internal foot in the air intake mode
• Fig. 4 shows a similar cross section of the shoe in the aerated mode of the foot.
• the sole can be made of rubber or a plastic material and the upper is attached to it in any one of the known ways.
• the sole 12 can be a single piece or, as shown in the drawings, it can be made up of two superimposed elements, one base element 12 resting on the sole and an internal element 15 where the foot rests with the interposition least of the usual sock-lining 16, at least an internal element 15 having its own degree of flexibility/elasticity.
• an air collection chamber 17 is formed in communication with the exterior through a duct 18 that extends up to a certain point in the part lying behind the upper.
• a longitudinal duct 19 is also provided between the two elements 14, 15 of the sole that extends in the intermediate part of the sole starting from the collection chamber 17 as far as the toe of the shoe, where it communicates with the retroflexed branch ducts 20 at the sides of the longitudinal duct 19, and through these, with some small additional chambers 21 in line with the toes.
• the additional chambers 21 communicate with the ducts 20 through narrow necks 21'; furthermore the branch ducts 20 and the additional chambers communicate with the interior of the shoe through the though ventilation holes 22 provided in the top element 15 and sock-lining 16.
• duct 18 that places the collection chamber 17 in communication with the exterior can be provided with or be without a one-way valve 18' so as to allow air to flow from the exterior to the interior of the chamber and not otherwise.
• the shoe When the shoe is worn by a person walking, it is the movement of the foot which provokes internal aeration of the shoe and consequently of the foot.
• the back foot which is about to be raised off the ground, is placed and presses the toe down, whereas the front foot is placed and presses against the ground using the heel.
• each foot is placed alternately on the toe and raised heel.
• the internal element 15 of the sole does not have the heel under pressure so that due to its elasticity it tends to lift up, enlarging the collection chamber 17 and taking air in from the exterior through duct 18.
• the heel presses on the internal element 15 of the sole, causing the air in the collection chamber 17 to become compressed, forcing it along the longitudinal duct 19 towards the additional chambers 21 and the branch ducts 20.
• the retroflexed branch ducts 20 besides contributing to the diffusion of the air inside the shoe through the aeration holes 22, act as air lungs under the arch of the foot and by closing the intake duct with a valve, if provided, or by some other means, the entrance of air from outside can be excluded so as not to cool the foot in particularly cold weather.
