Planning on making a pair of mukluks, and fortunately my old B.S. Fieldbook has a wonderful set of plans to make them!

So a couple of questions:

outershell material: looking for a breathable material that is highly water resistant, yet at the same time quite durable, what would one recommend?

Sole: Recommendation of any old boot bottom, but any other alternatives?

Insulation: My old field book recommends low density foam, what other alternatives would one recommend?

Plan on using them for trekking in snow and snowshoeing, hope this helps!

Consider e-mailing Empire Canvas Works for some recommendations. They are a company located in my town of Duluth, MN (land of the mukluk) and they may have some suggestions.

Good info, thanks!
