Abstract [en]

The UHMWPE (press-sintered) ski base and ski glide waxes are very similar substances. Hence, it should be possible to achieve a same or even better glide on a bare ski base. In this study we examined waxed and unwaxed skis before and after skiing for the purpose of gliding ability, dirt accumulation and wettability. We observed that the skis with unwaxed running surface did retain a same or higher comparative level of all three tested parameters. We can assume that it is a consequence of a soft wax dirt accumulation under warm conditions and of the excessively hot ski base treatment under cold and dry conditions.

Abstract [en]

It is no doubt, that the ski glide over the snow is a very complicated object of

research. However, ski glide is just a one area of many other areas of human

knowledge. As a rule, the scientists and practitioners, who work in these areas,

operate with some publicly expressed more or less solid hypotheses. These

researchers work with one hypothesis until another and a better one comes up.

Our literature studies and our own observations regarding modern skis

preparations, did not give us any solid hypotheses, which are able to explain the

actual form and content of this procedure. The present work is an attempt to reveal

such hypotheses.

Conclusion: To achieve an optimal glide on skis with the base (the ski sole)

made of some high hydrophobic durable polymer, e.g. UHMWPE, PTFE; we only

have to create an adequate topography (texture) on the ski running surface,

adequate to the actual snow conditions.
