Abstract [en]

In the cross country skiing community, hot wax treatment of the ski running surface (SRS) is used in order to influence the surface hardness of the skis in relation to the hardness of the snow crystals. This is discussed in a number of scientific papers and recommended in almost every ski waxing manual. The general idea is to decrease (soften) the surface hardness by the use of a soft glide wax treatment for wet snow conditions and to increase (harden) the hardness of the surface by a hard (synthetic) glide wax treatment for cold, dry snow conditions. The question is; does the hot glide wax treatment of the ski running surface influence the surface hardness? And if so, in what way?In our experiment, ski base specimens of UHMWPE (transparent and “graphite”) were treated with ski glide wax. Half of the specimens were treated with soft yellow glide wax, and half with hard green glide wax. After the wax treatment, the surface hardness (Shore D) was measured with a durometer. The study revealed that: both soft glide wax and hard glide wax treatment make the SRS softer; after a long immersion (12 hours) in the bath of melted glide wax, both the hardness of the specimens treated with soft glide wax and of those treated with hard glide wax decreased significant. Conclusion: The hot wax treatment of the SRS with available glide waxes cannot make the SRS harder than it was initially (unwaxed).

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.
