Dear Ruud,
Well moccasins/mukluks are not designed to deal with wet snow conditions, (such as is found in southern Europe). They are intended for COLD, DRY snow conditions. Typically, mukluks are worn with felted wool liners and felted wool insoles, as well as 2 pairs of wool socks. How we typically handle wet snow conditions over here in North American is to wear pacboots, (Sorrel, Kamik, or Acton), or Tingley moccasin rubbers OR N.E.O.S., (New England Over Shoes).
I should also mention that there is some debate amoungst us wintertrekkers as to what the 'ideal' winter footwear system actually is. As with many aspects of bushcraft, ask five people what the best tool is and you will probably receive as many different replies.
As to the the leather available to you, I believe that if you were to do an internet search for reindeer hides, you would find a number of relatively local suppliers.
Ruud, if you want a pair of self-made footwear for a trip to Sweden, you have a couple of options; either you wait until you arrive in Sweden, and pick up a pair of Saami footwear, or you take a deep breath and throw yourself into the project of learning how to make a pair of mukluks. As I mentionned in a previous post, George White has a fairly straight forward how-to booklet, (Craft Manual of North American Indian Footwear). There is also a book 'A Snow Walker's Companion' by Garrett and Alexandra Conover. I highly recomend this book! It has patterns at the back of the book which MANY, MANY people have used to make winter outdoor clothing, (mukluks, mittens, anoraks; even tents). Fairly simple directions. You might even look up
www.wintertrekking.com You will find alot of useful information there as well.
Remember, practice combined with focused intent, and a dogged determination, is the recipe for success. I am a self-taught moccasin and mukluk maker, some of my initial efforts did not bring the results I had hoped for . . . . I kept at it, and now I usually get the results I want. It takes practice, just like anything worthwhile in bushcraft.
Yes, I remember the episode with the Evenk, and the footwear which was made for him. Yes, there were alot of pieces to those boots. Most of which were for decorative purposes, very much like footwear found in western Alaska and the Canadian Arctic. The Burke Museum has a number of fine examples, as does The Museum of Civilization.
My suggestion for you is the following, find the pattern/style of footwear you want to make, practice making them using fabric, (old wool blankets is what I used, works great!), locate a source of suitable leather, then make them.
You will also need a few tools. Glovers needles or a Speedy Stitcher, artificial sinew, (basically heavily waxed polyester thread), a really good pair of scissors and loads and loads of patience. If you have all that, you will do fine.
All the best,
J
