Ski jumping equipment
Which run-direction should bindings be mounted, parallel or perpendicular?
Nordic combined
 Bindings  The binding must be mounted parallel to the run-direction. The binding must be placed in such a way that a maximum 57% of the entire ski length is used as the front part.  Boots  High-backed, flexible yet firm boots with a low cut at the front. They are designed to allow the skier to lean forward during flight.  Connection cord  Part of the binding; a cord that attaches the ski to the boot and prevents the wobbling of skis during flight.  Ski jumping suit  All portions of the ski jumping suit must be made of the same material and must show a certain air permeability. The size of the suit must conform to the body shape in an upright position with certain tolerances.  Jumping skis  Jumping skis are manufactured especially for use on ski jumping hills. Skis with a length of a maximum 146% of the total body height of the competitor may be used. The curvature and shape of the skis is restricted by certain geometric features.
