DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a vapor-permeable shoe.
BACKGROUND ART
It is known that a shoe, in order to be comfortable, must ensure the correct exchange of heat and water vapor between the internal microclimate of the shoe and the external climate.
This exchange of heat and water vapor, however, must not compromise in any way the tightness of the shoe with respect to external moisture or water.
Currently commercially available shoes entrust this heat and water vapor exchange substantially to the upper or to the sole.
As regards the upper, shoes provided with perforations and/or with linings made of vapor-permeable and waterproof material are currently commercially available.
In some models, parts of the upper may be replaced with materials that are indeed waterproof and at the same time vapor-permeable.
Another category of shoes instead entrusts vapor-permeability to the sole, again by using layers of waterproof and vapor-permeable material, optionally associated with protective layers and fillers.
DISCLOSURE OF THE INVENTION
A principal aim of the present invention is to provide a vapor-permeable shoe that allows the exchange of heat and water vapor both through the upper and through the sole, ensuring at all times an optimum internal microclimate as a function of the external climate.
Accordingly, an object of the present invention is to provide a vapor-permeable shoe the structure whereof is in no way restrictive in terms of styling and aesthetic research, allowing the greatest freedom in shoe shapes and types.
Another object of the present invention is to provide a vapor-permeable shoe that is meant both for everyday use and for sports use.
Another object of the present invention is to provide a vapor-permeable shoe the cost whereof is competitive with respect to the costs of conventional vapor-permeable shoes.
Another object of the present invention is to provide a vapor-permeable shoe that can be manufactured with conventional technologies.
This aim, these objects, and others that will become apparent hereinafter are achieved by a vapor-permeable shoe, according to the present invention, characterized in that it comprises the following combination of elements: lining; vapor-permeable material that is associated with a lower protective layer made of hydrolysis-resistant, water-repellent, vapor-permeable or perforated material; and said membrane; being perimetrically sealed in the coupling regions.
