From what I am looking at, that is not worth a stave of any kind of wood. More like an acknowledged master bowyers finished bow and set of matched arrows.
I spent a winter working in Saskatchewan, Manitoba, and western Ontario. I saw many pairs of these kinds of footware in various places and coveted them in the extreme. I spent an hour sitting with a Cree woman in The Pas, Manitoba during the winter Trapper's Festival talking to her about the traditions and craft of beadwork. All I could afford was a pair of beaded rose appliques that were about four square inches each. Fair market value for those eight square inches of beadwork should be about $200+, considering material, time, and sheer depth of experience necessary to produce traditional work.
A serious collector from Germany would easily cough up $750 for that pair of mocs with provenance tracing to the maker. For those interested, this is a heck of a deal!
