FIS Alpine Skiing World Cup has a lot of restrictions about skier's equipement and the jury is so strict about it. What about ski bindings?
2. Safety bindings
Safety bindings function as strain limiters. That is, these devices transfer
specific demands occurring during skiing to an acceptable limit, and when
this limit is overstepped, they release their firm hold on the ski.
2.1 Anti-vibration plates
Anti-vibration plates can be mounted if the following conditions are taken
into consideration:
2.1.1 Width of ski surface
The width of the plates must not exceed the width of the ski surface.
2.1.2 Maximum height
Maximum height (distance between the bottom of the running surface of
the ski and the ski boot sole) for all categories is 50 mm (Ladies, Men and
Children's). Specifications for Competition Equipment Edition 2013/14
2.2 Ski stoppers
The ski stopper is a braking apparatus for skis, the function of which
following the release of the safety binding is to stop or bring to a standstill
the loose ski within the immediate vicinity of the skier's fall. The use of skis
without ski stoppers during competitions or official training runs is
prohibited. The functioning of the release mechanism must not be
compromised by the method of its mounting. It is the manufacturers'
responsibility to ensure that the ski stopper functions correctly.
