A rotary supporting base (1) for a lever arm (2), particularly for sports shoes, comprising a plate (4) which has an approximately rectangular plan shape and can be associated with a flap of a shoe, two first wings (6a, 6b) protruding from the perimetric longitudinal edges of the plate, approximately at right angles thereto, the wings having a connecting and supporting bridge (7a, 7b) for two second wings (8a, 8b), which are bent and arranged approximately parallel and spaced with respect to the first wings (6a, 6b) so as to form between them two first seats (9a, 9b) for two tabs (10a, 10b) which protrude from one end of a lever arm (2); the first and second wings have first (11a, 11b) and second (12a, 12b) holes which are provided along the same axis so as to constitute second seats for means for the pivoting and support of the lever arm (2). |
