The machine (M) performs sewing of elements (E) to a bottom (F) for shoes, the bottom (F) being provided with an abutment (B) opposite the perimeter edge (22), extended to follow the edge (22). A positioning foot (10) provided with a slot (10A), which positioning foot (10) is fixed to a bearing body (11) solidly constrained to a head of the machine (M), which positioning foot (10) is able to abut against the abutment (B) in a zone of the abutment (B) from time to time affected in the sewing; a needle (4) mobile between a retracted position (R), in which it is external of at least one of said elements (E), the bottom (F) and the positioning foot (10), and an advanced position (A), in which the needle (4) is able to pass through the at least an element (E), then to penetrate laterally into the perimeter edge (22), then to exit at the abutment (B), then to transit through the slot (A) of the positioning foot (10) and then to enter a rotary-hook device (5), provided for cooperating with the needle (4) so as to realize stitches of the sewing (C); means for horizontally synchronically translating the needle (4) and the rotary-hook device (5) in an alternating motion in runs of an extension which is equal to a predetermined step.
