An interchangeable stud structure for sports shoes comprises a supporting element (2) which can be fixed to a sole (22) of a sports shoe, having a connecting seat (9), and a stud body (3) with a pin (10) that has at least one engagement tooth (11). The stud body (3) can be rotated relative to the supporting element (2) about an axis of rotation between a first position in which it can be removed and a second position in which the tooth (11) is coupled with the connecting seat (9) and secures the stud body (3) to the supporting element (2). The connecting seat (9) extends along a spiral trajectory coaxial with the axis of rotation and has an engagement zone (12) and a locking zone (13). Each point of the locking zone (13) is at a distance from the external side (7) not less than any other point of the connecting seat (9) between the engagement zone (12) and the locking zone (13).
