I would be very interested to see a picture
Here. This pair is made of Siberian pine wood (split, not sawn, for strength) by a Khanty craftsman. It's about 10 years old but still not much wear on it, except along the edge on the front part. The moose skins are sewn together with a nylon thread and glued to the skis with fish glue. Thanks to the stiff hairs you can trek up relatively steep slopes easily, because they don't slide backwards at all, and ski down, and the fur also makes them very quiet, which is necessary for stalking moose. This particular pair is about 5.5 feet long and 8 inches wide, which is enough to hold a total weight of ~200-220 pounds comfortably on any kind of snow. We use skis to check shorter traplines (up to 10 miles long) and for population surveying (which also usually involves 5-10 mile routes).
the straps are very simple. The bag is tied around the leg above the boot and serves to prevent snow from getting under the soles, so that it doesn't creak. You can use such skis with any type of boots. I usually wear insulated EVA boots, but for moose stalking, people wear soft insulated boots made of tanned moose leather or furred reindeer leg skins, to reduce noise.
Some people buy cheaper mass-market hunting skis, sold in all hunting/outdoors stores, usually made of thin aspen boards, and glue strips of moose leg skin to them. Some use cow and horse fur, but it doesn't work as well). Reindeer leg skins are also used sometimes; otter fur is a rare but also the most sought-after variant - otter skis are slightly less efficient for climbing steep hills, but they're also the quietest. There are also some commercial models made of laminated plywood with fur replaced by tufts of coarse hair glued into the lower surface, but I have no experience with them...
