The invention relates to a method for assembling a shoe (4), comprising a flexible upper (1) and a rigid sole (2). The method is characterized in that the assembly of the flexible upper (1) and the rigid sole (2) is achieved by using an intermediary part (3) obtained by shaping a flexible material. The method is also characterized in that it comprises at least two steps consisting in: covering a portion of the sole (2) with the intermediary part (3) in order to form a junction surface (12); exerting a pressure outside the shoe (4) in order to press the intermediary part (3) against the sole (2) at the junction surface (12).
