<p>This invention relates to a novel cross-country or excursion ski. The bottom of the ski, at least at the middle portion of the ski, that is, at the portion loaded by the foot, is made of a hard and elastic, massive polyacetal plastics material, whose surface is shaped as fluffy with sharp edges, the fluff length being approximately 0.01 to 0.1 mm. This construction provides the ski with good glide characteristics and good hold without the use of ski wax, which was not possible with the prior art devices.</p> |
