Well each jordan shoes are unique especially those shoes that Michael Jordan worn during his career and when Jordan retro his shoes people buy them and usually they sought after depending on the shoes. There are a lot of fakes out there though. There are ways to tell if they're fake

Yeah, I'll post some photos as soon as I have some free time to photograph all of the shoes.

It looks like the high bidder with zero feedback isn't going to pay in the auction above. Go figure. 

I don't sell on eBay enough to know the answer to this question but in a case like this where a bidder with zero feedback bids way more than the item is worth, can you reject his bid?

You have to report non-payment because if you don't then ebay is going to charge you with the 8% eBay fee.
