Ski binding equipment

A binding equipment for binding a hard-shell boot comprising:

• a profiled bottom surface to a water ski, the water ski comprising a bottom surface to be directed towards a gliding element and a top surface to be directed towards the boot, wherein the binding equipment is configured to adapt the top surface of the water ski to the profiled bottom surface of the boot;
• and,
• a distinct adaptation piece comprising:
• a substantially planar bottom surface configured to be attached to a planar support, the support being a base plate attached to the water ski or the water ski itself,
• a profiled top surface configured to be attached to the bottom surface of the boot, such that the bottom surface of the boot and the top surface of the adaptation piece are complementary, and
• a wedge configured for adjusting at least a portion of a height of an outer wall of the distinct adaptation piece by adjusting an angle of the distinct adaptation piece around at least one axis X, Y, Z of the base plate.
