The Air Mag shoes are a near identical replica to the original models worn by Michael J. Fox in the sequel to "Back to the Future," and represent the first pair of rechargeable sneakers from Nike.
Consistency with the original design exists across the shoe, from the upper contours to the glowing Nike emblem, but they don't feature power laces, contrary to early speculation.
Mark Parker, CEO of Nike, announced plans to auction off 1,500 pairs of the Air Mag aka "Marty McFly" shoe on eBay's Fashion Vault starting tonight at 8:30 p.m., with all net proceeds funneling directly into the Michael J. Fox Foundation for Parkinson's research.
For the duration of the 10-day auction, Nike will auction off 150 of the shoes until all 1,500 pairs are sold.
"We wanted to translate the excitement people have for the 'greatest shoe never made' and for the 'Back to the Future' into positive action," said Parker. "But the long-term objective is to raise awareness so the Foundation can achieve their goal of eradicating Parkinson's disease."
Michael J. Fox himself will appear on "The Late Show With David Letterman" tonight to show off the sneakers up close.
