A pedal system with a shoe insert and a pedal that is rotatably mounted on a pedal axle, the pedal having a seat for a detent element of the shoe insert, in which the detent element is engaged against a spring force and from which the detent element is detached by performing a rotating movement, wherein the seat is conformed between two seat parts that are constructed rotationally symmetrically about the pedal axle, which are slidably related to each other along the pedal axle under said spring force, and which are components of sleeves with cylindrical external surfaces outside of the seat, wherein the detent element is an elongated part that extends perpendicularly to the pedal axle when engaged in the seat, and which has two cams that clasp below the seat parts in the engaged position, the shoe insert having a control element which is forced against the cylindrical external surfaces of the sleeves in such a manner that when the shoe insert is rotated to release the detent element, the detent element is raised.
