A piston of an internal combustion engine, having a piston upper part (10) and a piston lower part (11), having a piston pin (12) which is mounted in the piston lower part (11) and which serves for connecting the piston to a connecting rod (13) of the internal combustion engine, having an inner cooling chamber (15), formed between the piston upper part (10) and the piston lower part (11), for cooling oil for cooling the piston, said inner cooling chamber being connected via at least one transfer bore (17) to an outer cooling chamber (16) formed between the piston upper part (10) and a piston lower part (11), and having a single-piece slide shoe (19) which is movably mounted in the piston lower part (11) and which is forced by means of a spring element (20) against a connecting rod head (14) of the connecting rod (13) and which serves for transferring cooling oil, which has been conducted through a bore (18) in the connecting rod (13), into the inner cooling chamber (15), wherein a guide surface (21) for the single-piece slide shoe (19) is formed between the single-piece slide shoe (19) and the piston lower part (11), and wherein, as viewed in the axial direction of the piston and slide shoe, the spring element (20) extends, at least in sections, parallel to the guide surface (21) for the single-piece slide shoe (19).
