The roller skate has a boot (31), at which a sole of a roller support element is mounted. The roller support element has a symmetrical plate (1) detachably connected to the sole of the boot, where two bearing blocks (6,7) are firmly connected to the plate. The bearing blocks are formed as mirror images to the vertical axis of symmetry (5) of the roller skate, and are identically designed and arranged. |
