Nike has produced 1500 pairs of replica shoes based on the pair that Michael J. Fox wore in the 1989 movie Back to the Future II. The shoes are available on Ebay until September 18. They have sold there for prices between $3,500 and $10,000. At a live auction last week, British rapper Tinie Tempah paid $37,500 for a pair.
All proceeds are being donated to the Michael J. Fox foundation for Parkinson’s disease research—plus, Google’s Sergey Brin will match all proceeds up to $50 million through the end of next year.
The shoes contain LED panels, the word “Nike” on the strap glows. The batteries last for about five hours per charge.
Tinker Hatfield, who worked on the original shoe for the movie, created the new version. According to Nike, the shoe’s being released meant it was no longer “the greatest shoe never made.”
