The present invention relates to a vapor-permeable waterproof sole for shoes.
Conventional shoes with rubber soles are widely commercially available which are capable of ensuring a particular level of practicality and comfort which is appreciated most of all by young people and individuals engaged in sports; such soles, however, do not allow any transpiration of the foot.
As disclosed in Italian Patent no. 1,232,798 and in WO-A-97114326, shoes have long been known which have a rubber sole through which correct transpiration is ensured by virtue of an effective exchange of heat and water vapor between the environment inside the shoe and the outside environment. These rubber soles ensure at the same time the necessary watertightness with respect to external moisture and water.
The particular technical characteristics and advantages of the present invention will become apparent from the following detailed description of some embodiments thereof, illustrated only by way of non-limitative example in the accompanying drawings, wherein:
FIG. 1 is a sectional elevation view, taken along a longitudinal plane, of a sole according to the present invention in a first embodiment;
FIG. 2 is an exploded view of the sole of FIG. 1;
With particular reference to the above described FIGS. 1 to 4, a vapor-permeable and waterproof sole according to the present invention is generally designated by the reference numeral 10 in a first embodiment.
The sole 10 comprises a shaped lower element 11 which is made of rubber-like material (i.e. organic rubber or any of various artificial polymeric substances) and which is preferably made of elastomer, and in which a tread 12 is integrated in the lower part; the lower element has, in its upper part, a hollowed-out or hollow region 13 delimited perimetrically by a border 14.
Dome-shaped raised portions 15 protrude from the bottom surface of the hollow region 13 and in this case are uniformly distributed and reach the same vertical level as the border 14.
