FIELD: personal use articles.
SUBSTANCE: shoe sole (100; 200; 300; 400) includes support layer (101; 201; 301; 401), which has at least one area (103; 203; 303; 403) that makes it possible for air to pass through layer (101; 201; 301; 401). It includes one or more reinforcement elements (111; 211; 311; 411), connected to one side of layer (101; 201; 301; 401) in at least one area (103; 203; 303; 403), where through holes are arranged (113; 213; 313; 413) for removal of air that has passed through the area; and membrane (117; 290; 390; 417). The latter is made of material, which is water impermeable and steam permeable, and is arranged over at least one area (101; 201; 301; 401) opposite to elements (111; 211; 311; 411). At the same time membrane is tightly connected to layer (101; 201; 301; 401) at least along one contour (115; 215; 305) around at least one area (103; 203; 303; 403). Such connection makes it possible to form air chamber (140; 288; 388; 488) over at least one area (103; 203; 303; 403). At the same time membrane has at least one freely oscillating section, acting as pumping surface in process of foot motion. Compression and expansion of air chamber produced as a result provides for generation of air flow, which passes through at least one area (103; 203; 303; 403) and holes (113; 213; 313; 413) of one or more reinforcing elements (111; 211; 311; 411). Shoes may also be produced with a sole according to invention.
EFFECT: increased efficiency of moisture removal from shoes and elimination of membrane damage in process of operation.
