Rare style Wild Pair vintage thigh-high boots with fringe fetch an impressive price

These nicely modeled vintage Wild Pair black leather thigh-high boots with fringe sold for a very impressive $192.50.  I suspect these boots sold for such a high price for a few reasons 1) the large size and 2) the rarity of this style on eBay and 3) what appears to be no wear on the soles!
