These appear to be basically moccasins with an extra piece sewn in on the inside at the instep. Tandy sells a little book of Native American moccasin patterns, and there are some in there that are similar to these shoes. You would probably need to experiment with some cheap split leather first. Getting the heavy sole molded to turn up around the edges would be the hardest part I think. I'm guessing you would need a shoe last or some kind of mold for that.
