This ski works quite
differently from any other type of ski. So be patient to try to figure it out
because it is really quite ingenious.First of all the ski doesn’t
have wheels that contact the ground. The Bottom ski is a plastic ski looking
part set on the ground. Then you glide across the bottom ski with the slider
carriage. At the end of the glide you shift your weight to the other ski and
the ski shoots forward. Repeating the cycle on the other ski. Because you are
not gliding on the ground but on the bottom ski, you always have a perfectly
smooth surface you are gliding on. This is what makes it work so well on all
surfaces.
