Aerated shoe having cushioning effect, with air flow regulator

Abstract

An aerated shoe with cushioning effect includes a double sole (3, 5) with border (10) defining a hollow space between the two soles. The lower sole (5) does not have holes; the upper sole (3) has holes or micro-holes, allowing the passage of the atmospheric air towards the shoe interior, air which first crossed through the slits (12) on the border (10). Elements (7) are provided between the soles for ensuring the suspension and the movement of the air (ventilation) during walking. An air flow regulator, lockable in the desired position, selectively opens the slits (12). The regulator is preferably inserted in a continuous perimeter slot (11) of the border (10). The shoe ensures a natural entering / exiting air flow, quantifiable in a precise manner.

Description

FIELD OF THE ART[0001]The present invention refers to the industrial field of footwear, and in particular of aerated shoes, i.e. those provided with means which permit atmospheric air to enter, naturally in a limited manner, inside the shoe, so to give a feeling of comfort to the user's foot.PRIOR ART[0002]Shoes of every type and form are already known in this sector that have ventilated or aerated sole.[0003]The aeration inside the shoe by means of the entrance of air from the sole or laterally makes the foot comfortable and determines a secure remedy against sweating. Nevertheless, it is also true that in the shoes whose aeration is obtained by means of sole perforation, there is always the problem of passage of moisture inside the shoe and towards the foot—even if the air is “filtered” by means of a membrane, since the sole is in contact with the underlying ground.[0004]On the other hand, it has been shown that the air which enters the shoe for remedying the sweat problem should ...

AI Technical Summary

Benefits of technology

[0022]The dependant claims specify several preferred, but more particular embodiment variants. By making the movable part (13) of the flow regulation device in the shape of a closed belt, semi-rigid but flexible, which extends along the entire side of the shoe and is slidable within a perimeter groove (11) of said border (10), the shoe assumes an improved aesthetic appearance.

[0024]Preferably, a positioning lock (locking means) is provided for, adapted to prevent undesired movements of the semi-rigid belt.

Problems solved by technology

Nevertheless, it is also true that in the shoes whose aeration is obtained by means of sole perforation, there is always the problem of passage of moisture inside the shoe and towards the foot—even if the air is “filtered” by means of a membrane, since the sole is in contact with the underlying ground.

Indeed, if the system is such that the air enters from the sole, it naturally rises towards the foot, while if it enters laterally with respect to the foot it has a hard time flowing downward, i.e. under the foot.

In addition, in both technical solutions, the volume of air which flows inside the shoe towards the foot cannot be modified by the user.

In other words, currently there are no practical and functional systems which allow for a regulation of the air flow rate.

The disadvantage of this state of the art is easily illustrated.

In addition, even with the heat, it does not always make the foot comfortable, since sensitivity varies from person to person.

Thus, even more so, in cold weather, the impossibility of regulating the air flow rate constitutes a real problem, since with the entrance of cold air there is inevitably a lowering of the temperature inside the shoe, which is immediately felt by the sole of the foot (being a sensitive area).

A non-suitable air flow also causes foot discomfort.

An uncontrolled air flow towards the foot is like the classical “draught”, always annoying and possibly even harmful.

Particular mechanical expedients are avoided for modifying the entering air temperature, which in addition to being costly and hard to apply would not bring about the desired benefits, but rather, considering the foot's sensitivity, could even prove to be harmful.
