Device for driving a pair of skis or a surfboard

A drive device for driving a pair of skis, comprising:

• a first zone for fastening the feet, located substantially on a first half of the pair of skis, the perpendicular of the pair of skis at the first zone with a first axis, longitudinally passing through the pair of skis at the center of gravity thereof, forming a first plane with the first axis;
• and
• a second zone for fastening the feet, located substantially on the second half of the pair of skis, the perpendicular of the pair of skis with the first axis at the second zone forming a second plane with the first axis,
• the device comprising:
• a first connecting element connected to the pair of skis at a first end by a first base at the first zone and constrained at least parallel to the first plane in a first point at a second end;
• a second connecting element connected to the pair of skis at a third end by a second base at the second zone and constrained at least parallel to the second plane in a second point at a fourth end;
• a warping element connected to the first connecting element at least at the first point, to the second connecting element at least at the second point, and maintaining a fixed and predetermined distance between the first and second points, the free mobilization of the warping element imposing an offset of the second point relative to the first plane and of the first point relative to the second plane.
