I am reading that these are military and function as both Nordic (cross-country) and Alpine (downhill) skis. They are pretty wide for Nordic skiing, and they do not have the characteristic, severely upswept tip of a true Nordic ski. The moderately upswept tip, width, and the metal edges are characteristic of downhill skis. I think that these are most similar to telemark skis, where one descends downhill, but with a cross-country like style ("free heeling") sometimes dragging one ski behind for stability and braking. I believe this idea is reinforced by the stipulation for boots without a flexible sole. Telemarkers wear mountain climbing expedition-style stiff high-top leather boots, whereas Alpine skiers wear hard, mid-calf plastic boots that nearly immobilize the foot, and cross-country skiers wear something like soft high-top sneakers with an inflexible sole. It seems like you'll need some special-issue military Alpine hiking boot with holes drilled in the toe to use those bindings, but I could be wrong. I believe that these will descend the mountain in a "free heeling" way well, but "fixed heel" control downhill is not a strong suit, and neither is cross-country travel. I think these are "general purpose," and may be more valuable to a survivalist than a recreational skier.
Does anyone else get this impression too? Correct me if I a wrong anywhere.
