These do appear to be in amazing condition - freshly polished and with pristine sole treads and new heel tips.
As someone who has bought and sold these boots on eBay, I've seen them go as high as $425, especially during the holiday selling season. My best experience selling these boots was a size 8 pair, new without tags, which I sold for $303 back in 2012. About the only Wild Pair style that fetches more than these is their chap boots.
I'll be glad to report back to see if and how quickly these boots sell for their current Buy It Now price of $399.
UPDATE: As of 10/26, about four days after the auction began, these sold for their Buy It Now price of $399.99. Kudos to the seller for getting a very impressive price for these rare boots in new condition!
Meanwhile, here's the seller's text:
AMAZING.. BRAND NEW! SIZE 10! A lot of Wild Pair collectors consider the WP crotch boots to be the most desirable of all the Wild Pair vintage boots. What makes this pair even more special is the fact these are like brand new and have never been worn only tried on! Also, the large size (10) make these super rare. Larger sizes in most Wild Pair boots are very hard to come by. The leather on these is unbelievable! Buttery soft, slinky and smooth. Pull on. They are longgg! 35 inches in total length! 4” stiletto heels and 22” circumference at the top. Rear gusset at the top allows for ease of sliding these babies on and also provides that desired sexy look! They can be worn ultra high, scrunched or folded at the top. The black sole protectors on the bottoms are original and still brand new without a scuff because these have never stepped foot outside. I had the heel taps replaced just due to the age of the unused original taps. Please keep in mind Wild Pair boots tend to run a bit small so know your size in Wild Pair. I consider these a “holy grail” type find and I’m on the fence about letting these beauties go so this listing may not be up very long! Last 4 pics are not the actual boots, they are just to show how they look on cuffed and uncuffed.
And some modeled photos pulled from somewhere else online...
Not sure that I've ever seen these photos, but this all black leather outfit is stunning!
