FOOTWEAR ARTICLE WITH AIR-PERMEABLE LAYER AND AIR-PERMEABLE SECTION IN TOP LOWER PERIPHERAL AREA Russian patent published in 2017 - IPC A43B7/12 

FIELD: footwear.

SUBSTANCE: footwear article (10) contains top (20) and sole (30), wherein said top (20) contains top material (12) in lower peripheral area containing, at least, one air-permeable section (14), air-permeable layer (16) located at top (20) lower area on sole side above sole (30), wherein said air-permeable layer (16) is vapor permeable and has three-dimensional structure, which provides air passage in, at least, horizontal direction; and, at least, one vapor-permeable functional layer (18), arranged on top material (12) inner side and above air-permeable layer (16). Said, at least, one air-permeable section (14) provides such communication of air-permeable layer (16) with ambient environment, that air exchange between ambient environment and air-permeable layer (16) is carried out, wherein said air-permeable section (14) is additionally provides such communication of vapor-permeable functional layer (18) with ambient environment, that water vapors are moved from functional layer (18) inner side into ambient environment.

EFFECT: vapor-permeable first protective layer (22) is located between air-permeable section (14) and functional layer (18) in, at least, one of air-permeable section (14) area above air-permeable layer (16), wherein said first protective layer (22) is made with possibility of functional layer (18) protection against particles, penetrating through air-permeable section (14).
