Also shown are two rails 14 on the left and right shoe shafts (not shown) that extend from proximal to distal and are respectively disposed in proximal and distal seats. Here, a left and right cassette 15 are shown as proximal recording. The cassettes 15 each have two notches 16 for fixing the rails 14. Here, the notches 15 are shown substantially in the diameter of the rails 14. Thus, the rails 14 can each be fixed in 2 positions or positions and the angle between the rails 14 can be increased or decreased. As already mentioned above, a different anatomical condition of feet can be taken into account by this advantageous embodiment. Further, a flexible element 17 is shown here as a distal recording, which is deformable in all directions. The flexible element 17 has an adjusting screw 18 and is split in half centrally by the adjusting screw 18. Here, the flexible member 17 connects the rails 14 with each other by making a rounding.
