The laminated insole (2) for a footwear comprises an upper layer made of a resilient foam material (4) and having an outline (6) shaped for incorporation in the footwear, and a bottom layer made of fibrous mat (10) and having a shape conforming with the outline (6) of the upper layer (4). The fibrous mat (10) comprises a multiplicity of fibers (12), a fraction of which penetrates the foam material of the upper layer (4) for bonding the bottom layer (10) to the upper layer (4), and a stiff portion (14) for providing stiffness to the insole (2). Preferably, each of the fibers (12) of the fraction penetrating the foam material (4) emerges from the outer surface (16) thereof and thereby provides a pilosity (17) thereon. The laminated product (2) is suitable for use as an insole as well as a slip-in insole in any footwear. It takes advantage of the resilient properties of the foam, the stiffness and thermoformability of the fibrous mat and the comfort provided by the pilosity covering the upper layer of foam.

Semelle (2) stratifiée de chaussure qui comporte une couche supérieure constituée d'une matière (4) en mousse souple et dotée d'un contour (6) permettant de l'intégrer dans la chaussure, et une couche inférieure sous forme de mat fibreux (10) de forme correspondant au contour (6) de la couche supérieure (4). Le mat fibreux (10) contient une multiplicité de fibres (12), dont une partie pénètre dans la matière en mousse de la couche supérieure (4) de manière à coller la couche inférieure (10) à la couche supérieure (4), et une partie rigide (14) destinée à donner de la rigidité à la semelle (2). De préférence, chacune des fibres (12) de la partie qui pénètre dans la matière en mousse (4) émerge de la surface extérieure (16) de ladite matière en mousse, créant ainsi une pilosité (17) sur ladite matière. Ledit produit stratifié (2) est approprié pour être utilisé comme semelle, ainsi que comme semelle interne à introduire dans n'importe quelle chaussure. Ses avantages sont les propriétés de souplesse de la mousse, la rigidité et la thermoformabilité du mat fibreux et le confort donné par la pilosité couvrant la couche supérieure en mousse.
