There are two more factors to consider when choosing between a waxable or waxless ski. First, find out what skiing partners or other family members are using and strongly consider using the same style. If they have waxable skis, it could be hard to keep up with them using waxless skis. If they have waxless skis, they might grow impatient waiting around while somebody else waxes up. Second, a waxless ski will make a grating sound as it slides across icy or packed snow.
Waxable skis tend to result in a more pleasurable auditory experience.
Once the classical skier has decided to go waxable or waxless, it's time to find the right length of ski. The general rule for this is simple. Stand up, raising one arm above the head. The length of the classical ski should be the distance from the wrist joint to the floor. Exceptions to the rule can be caused by weight of the skier or stiffness of the ski.
