Abstract: A method of manufacturing a footwear includes the steps of providing a leather base layer and providing a leather attachment layer. The leather base layer and the leather attachment layer are fixed against each other with an intermediate application of adhesive between them. The applied adhesive is activated. The leather base layer and the leather attachment layer are forced against each other under a pressure with the adhesive between them. The adhesive is cured and thereby the leather base layer and the leather attachment layer are bonded to each other. The bonded leather base layer and the leather attachment layer are integrated as part of the footwear.
