A custom shoe, in particular an orthopedic shoe, and a method of producing the same, in which a shoe upper (1) with an opening (11) for an insole is produced, is drawn with a sewn-in insole over a last (8) and is completed to form the shoe by joining the upper (1) to a sole (17). Formation occurs more easily and inexpensively by addition of an insert (6, 6') of an elastic textile material provided in the opening (11) and/or at a lower border of the upper (1) adjacent to a sole region. The upper (1), with the elastic material, is drawn over the last (8), stretching the elastic insert (6, 6'). The elastic insert (6, 6') is fixed in the stretched state by applied, non-elastic material.
