The invention relates to a sports shoe (1), in particular a ski shoe (2), consisting of a shoe bottom part (3) comprising a sole (4) and a shell part (5) with a cuff part (7) pivotably connected to the shoe bottom part (3), and a lock mechanism (16) incorporating at least one locking means (17) displaceable between the shell part (5) and the cuff part (7), as well as an actuator drive (29) for the locking means (17). The actuator drive (29) is conductively connected to an energy store and/or an energy source (42) disposed in the shoe bottom part (3) or in the cuff part (7) and a switch means (44) is connected upstream of the actuator drive (29) to supply the actuator drive (29) with power from the energy source (42) and/or the energy store.
