Old Shoe Vintage Advertising Key Chain (1)

Strange, beat-up shoe key chains. If you prefer, take the shoe off of the key chain and use for a craft or jewelry project. The sole of the shoe says "DAX FÖR KULLENS SKOR" - I have no idea what this means - Swedish? Norwegian?
These are old stock found in the basement of a defunct novelty shop. Measures 1-3/4" in length and about 1" tall, not including the key chain. Priced per piece.
