• the skier is connected to the board by means of two retaining elements which hold each of his boots.
• the retaining elements are generally offset along the median longitudinal axis of the plate and they form an angle of 5 to 90 degrees with this axis on one side or the other of this axis. This angle as well as the distance between the two retaining elements can be adjustable.
