Although they weren't originally listed as "Wild Pair," but simply as "Brazilian," these vintage Wild Pair black leather crotch-high boots sold for $129.16. These size 8 boots were listed with 34" shafts. The seller later added the Wild Pair brand name to the listing in response to a question.
Although the boots had a fair amount of wear on the soles and some knicks on the toes, someone got a good deal on these as this style in this larger size has recently sold for up to $275.
