• wherein a shoe last is arranged within the shoe upper, and wherein the shoe upper and the shoe sole are placed in a negatively shaped holding part for due adjustment between the shoe upper and the shoe sole, and to hold the shoe upper and the shoe sole together, the negatively shaped holding part also being inserted into the flexible container element;
• closing and evacuating the flexible container element, so that the flexible container element presses together the joined shoe upper and the shoe sole within the flexible container element;
• connecting the shoe upper and the shoe sole within the flexible container element by applying a microwave radiation to a contact zone between the shoe upper and the shoe sole, wherein the microwave radiation is applied from outside the flexible container element;
• and
• venting the flexible container element and taking the connected shoe upper and shoe sole out of the flexible container element.
