Which structure is suitable for what? And which one is for a sporty all-round piste skier?
Today, the base structure is more important for the gliding ability of your skis than the right wax. The fine groove structure breaks up the water film that forms between your ski and the snow. It is important that there is not only a structure in the ski that runs parallel to the edges of the ski, but also a structure that crosses them (we speak here of a crossed structure).
This grinding structure is created by the different speeds at which the grinding stones are removed with a diamond in the ski service machines. This is reground with every ski service and is therefore not "fixed" and can be changed depending on the type of snow. A slightly deeper, coarser structure is recommended for wet snow, while a finer, flatter structure provides better gliding properties at low snow temperatures.
Despite all the patent recipes for structure, wax should not be missing, and it is advisable to hot wax the ski at least every two to three days.
