In order to produce a shoe without insole, the lasting fold of a shoe upper (4) is glued directly on the underside of a last (1), specifically with the use of an adhesive which is selectably releasable at some later time. Next, an outside sole (5), which is provided with an adhesive layer (6) in the area of the lasting fold and possibly in the area of the side leather, is glued to the shoe upper (4). Next, the adhesive power of the selectably releasable adhesive is cancelled, for example, by means of heating, and the adhesive power of the adhesive (6) between the shoe upper (4) and the outside sole (5) is increased. Now the last (1) can be removed from the completed shoe. Such a shoe without insole is particuarly suited as an orthopedic shoe which makes possible a direct contact between the foot and the soft upperside of the outside sole (5).
