CA 2728053

A water-vapour-permeable and water-permeable sole unit (15) for footwear (11), having at least one sole layer (25) with at least one large aperture (27) extending through the thickness thereof and at least two sheet-like formations arranged one on top of the other, which seal the at least one aperture and of which a first sheet-like formation has a textile water-vapour-permeable barrier layer (39) and a second sheet-like formation has a water-vapour- permeable decorative layer (45), which is arranged under the first sheet-like formation, at least in the region of the at least one aperture, and is visible from the underside of the sole layer (25) in the at least one aperture. A decorative layer (45) according to the invention allows the achievement of aesthetic and visual design possibilities for the appearance of the underside of the sole unit (15) that would either be prevented by the material of the fibrous layer (39) or could only be accomplished with the fibrous layer (39) with some difficulty.

La présente invention concerne une unité semelle (15) pour chaussure (11), laquelle unité semelle est perméable à la vapeur d'eau et perméable à l'eau et comprend au moins une couche de semelle (25) qui comporte au moins un grand évidement (27) s'étendant sur son épaisseur et au moins deux structures planes superposées qui ferment ledit évidement, une première structure plane présentant une couche barrière textile perméable à la vapeur d'eau (39) et une seconde structure plane présentant une couche décorative perméable à la vapeur d'eau (45). La seconde structure plane se trouve sous la première structure plane, au moins dans la région dudit évidement, et est visible dans l'évidement depuis le dessous de la couche de semelle (25). La couche décorative (45) permet d'offrir des possibilités de configuration esthétiques et optiques pour l'aspect du dessous de l'unité semelle (15) qui permettent de bloquer la vue du matériau de la couche de fibres (39) ou qui ne seraient obtenues à l'aide de la couche de fibres (39) que de manière très complexe.
