Method of manufacturing a footwear

A method implemented by an automatic footwear processing arrangement having an input (I) and an output (O), wherein a method of providing a leather base layer and a leather attachment layer is performed in an automatic process comprising:

• transporting the leather base layer and the leather attachment layer from the input (I);
• and
• stacking the leather base layer and the leather attachment layer, one layer at least partially overlapping the other layer,
• wherein an activation of an adhesive is performed automatically via an automatic adhesive activation arrangement,
• wherein the automatic adhesive activation arrangement subjects the adhesive to heat continued over a period of time, and/or to a temperature, by which at least one of the leather base layer and the leather attachment layer shrinks to within a predetermined dimension range, and
• wherein the process further comprises forcing the leather base layer and the leather attachment layer against each other under a pressure P with the adhesive between them via an automatic pressure activation arrangement.
