A mold (10) for providing shoe soles and shoe sole portions, comprising a lower plate (11) that forms, together with lateral containment portions (12) and with an upper closure piston (13), at least one shoe sole impression (14). The lower plate (11) and the lateral containment portions (12), when arranged so as to close onto the lower plate (11), form, along substantially mutually opposite parts of the perimeter of the at least one impression (14), corresponding undercut slots for supporting and locking laterally the outer edges of a preformed insole (16). The preformed insole (16) is provided with channels (22) that pass through its thickness and is obtained from a sheet of polymeric material. <IMAGE>
