Piston for use in internal combustion engines, having a piston skirt composed of skirt walls (12) and box walls (16), said walls enclosing a recess (20), wherein the at least one skirt wall (12) is provided for use on the pressure side of the piston (10) in the installed state. Said piston is in particular characterized in that, in at least one partial region (22) of at least one skirt wall (12) provided for use on the pressure side of the piston (10), the recess (20) is in substantially the shape of a parabola, a section of an ellipse or a catenoid, wherein said parabola, said section of an ellipse or said catenoid lies in a plane substantially parallel to the piston crown. |
