Abstract
Abstract The sole structure comprises a lower part with a tread, preferably made of rubber or other synthetic material, and having holes formed therein which traverse its thickness. The lower part is covered by a membrane made of microporous, waterproof material which permits transpiration. The structure is completed by an upper part adapted for having a foot rested thereon and being made of rubber or other synthetic material. Holes which traverse the thickness of the upper part are provided at the portion thereof affected by the membrane.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
185 words
Sole structure for footwear, comprising an outsole which comprises at least one lower part and at least one upper part which are mutually united to form said outsole, said lower part defining an area at which a plurality of holes is provided which transverse said lower part, said upper part defining a zone at which through holes are provided which traverse said upper part, said outsole further comprising at least on microporous waterproof membrane means sandwiched between said mutually united upper and lower parts, wherein said lower part defines a lower part perimetric region encompassing said area and said upper part defines an upper part perimetric region encompassing said zone, said lower part perimetric region being a lower part coupling region and said upper part perimetric region being an upper part coupling region, said lower part and said upper part being mutually united at said upper part coupling region and said lower part coupling region in a manner to create a fluid-tight seal at said coupling regions, said membrane means being arranged between said upper part and said lower part inside said coupling regions thereof.
Claim 2
Dependent Claim
185 words
Sole structure for footwear, comprising an outsole which comprises at least one lower part and at least one upper part which are mutually united to form said outsole, said lower part defining an area at which a plurality of holes is provided which transverse said lower part, said upper part defining a zone at which through holes are provided which traverse said upper part, said outsole further comprising at least on microporous waterproof membrane means sandwiched between said mutually united upper and lower parts, wherein said lower part defines a lower part perimetric region encompassing said area and said upper part defines an upper part perimetric region encompassing said zone, said lower part perimetric region being a lower part coupling region and said upper part perimetric region being an upper part coupling region, said lower part and said upper part being mutually united at said upper part coupling region and said lower part coupling region in a manner to create a fluid-tight seal at said coupling regions, said membrane means being arranged between said upper part and said lower part inside said coupling regions thereof.
Claim 3
Dependent Claim
21 words
Sole structure according to claim 1, wherein said membrane means of said outsole is comprised of waterproof material which permits transpiration.
Claim 4
Dependent Claim
46 words
Sole structure according to claim 1, wherein said lower part and said upper part of said outsole are united by press-glueing in which a separately molded said lower part and a separately molded said upper part are united at said coupling regions by means of adhesives.
Claim 5
Dependent Claim
32 words
Sole structure according to claim 1, wherein said outsole is obtained by injection molding in which said lower part and said upper part are mutually monolithic, said membrane means being embedded therein.
Claim 6
Dependent Claim
185 words
Sole structure for footwear, comprising an outsole which comprises at least one lower part and at least one upper part which are mutually monolithic, said lower part defining an area at which a plurality of holes is provided which traverse said lower part, said upper part defining a zone at which through holes are provided which traverse said upper part, said lower part defining a lower part perimetric region encompassing said area and said upper part defining an upper part perimetric region encompassing said zone, said lower part perimetric region being a lower part coupling region and said upper part perimetric region being an upper part coupling region, said lower part and said upper part being mutually monolithic at said upper part coupling region and said lower part coupling region thereby creating a fluid-tight seal at said coupling regions, said outsole further comprising at least one microporous waterproof membrane means sandwiched between said mutuallly monolithic upper and lower parts, at least a portion of said microporous waterproof membrane means being arranged between said area of said upper part and said zone of said lower part.
Claim 7
Dependent Claim
185 words
Sole structure for footwear, comprising an outsole which comprises at least one lower part and at least one upper part which are mutually monolithic, said lower part defining an area at which a plurality of holes is provided which traverse said lower part, said upper part defining a zone at which through holes are provided which traverse said upper part, said lower part defining a lower part perimetric region encompassing said area and said upper part defining an upper part perimetric region encompassing said zone, said lower part perimetric region being a lower part coupling region and said upper part perimetric region being an upper part coupling region, said lower part and said upper part being mutually monolithic at said upper part coupling region and said lower part coupling region thereby creating a fluid-tight seal at said coupling regions, said outsole further comprising at least one microporous waterproof membrane means sandwiched between said mutuallly monolithic upper and lower parts, at least a portion of said microporous waterproof membrane means being arranged between said area of said upper part and said zone of said lower part.
