Shoe Comprising A Ventilation In the Bottom Zone Of the Upper And Air-Permeable Spacing Structure Usable Therefor

Abstract

Disclosed is a shoe ( 10 ) comprising an upper arrangement ( 12 ) and a sole ( 14 ). The upper arrangement ( 12 ) has a top upper material ( 16 ) and an air-permeable layer ( 40 ) that is disposed at the bottom of the upper. The air-permeable layer ( 40 ) is disposed in a bottom zone of the upper arrangement ( 12 ) above the sole ( 14 ) and has a three-dimensional structure which allows air to flow therethrough at least in the horizontal direction. At least one air passage opening ( 20 ) is disposed in the lower circumferential zone of the top upper material ( 16 ) near the sole. Said opening ( 20 ) is connected to the air-permeable layer ( 40 ) in such a way that air can be exchanged between the surroundings and the air-permeable layer ( 40 ) via the air-permeable layer ( 40 ).
