(Written in 2011 Updated in 2013 including this introduction) For almost two decades since the film came out showing "self-lacing" Nike shoes, fans have wanted a chance to purchase a pair- even if they didn't work (for display?). Many have tried to convince Nike to build them but until now there was no viable way to do that (i.e. because the shoe on the show was only a prop, it didn't really work!). When Mike asked them to do it as a fundraiser they saw an opportunity to do both and ran with it. It's not clear to me if he paid for it or if they just did it due to the notoriety and charity surrounding it.
The shoes would be promoted for several months before being introduced and they would only be sold in a limited number. They would sell on eBay for a limited time and they wouldn't be cheap- unless $6,000.00 for a pair of Nike Air Mag's is what you consider cheap or affordable. The idea wasn't to get everyone to buy them but rather to consolidate the purchasing to a high end audience who'd bid on them for a certain amount of time. They went well over 20k each and the charity was funded- yay!
Below I'll consolidate my research (back then) and show you how cool it is including videos and pictures of these bad boys and one video created as one of the attempts to get Nike to build them. Michael J. Fox showed power in this one, of course who else could have?!
