A stroke piston for a stroke piston compressor for generating compressed air for a vehicle, such as a commercial vehicle, includes a piston body with a piston floor, a piston skirt with piston skirt walls and pin hubs for receiving a piston pin, and at least two piston rings, which can be inserted into circumferential ring grooves of the piston body. Ridges of the piston body are provided between each two ring grooves and between the piston floor and the first ring groove arranged closest to the piston floor and the ring groove arranged closest to the piston skirt facing away from the other ring groove or grooves. At least one of the ridges is recessed at least over a partial section of its ridge height, which is measured parallel to the axis of the piston body, with at least one recess relative to the diameter of the piston body.
