The shoes graced the front cover of the Daily News, one of New York city’s most read newspapers. The shoes caused riots at a Florida mall Foot Locker this morning and bidding became frantic on eBay — as of this morning, a pair listed on eBay was up to $70,000.

According to @nikestore, Nike would not be releasing the Foamposites online due to extremely limited quantities. Is Nike the best brand at creating buzz around product launches?
