Kanye West Niki's Shoes Going For $80K Online

The Air Yeezy 2's don't drop until Saturday -- but people have been camping outside sneaker boutiques across the country for over a week, hoping to get their hands on a pair.

But a lucky few were able to pre-order the kicks -- and some of these people have already pre-listed them on eBay.

The online auctions range in value -- but one has already reached $89,100 ... FOR ONE PAIR!!!

The last time people went this nuts for sneakers was last December -- when Nike released a new edition of the classic Air Jordans.
