If you've been dreaming about owning the special sneakers that Michael J Fox's character wore in Back to the Future II in 1989, guess what?  Wait no more!

Think how cool you would look at the office wearing these babies.There aren't many of them available, but if you're feeling lucky and you're willing to bid on ebay, you just might get a pair.

The auction began Thursday night on eBay, with 150 pairs up for grabs each day through September 18.  Proceeds will benefit The Michael J. Fox Foundation, which seeks a cure for Parkinson's disease.  Google founder Sergey Brin and his wife have offered to match donations from the sales of the sneakers up to 50 million dollars through the end of 2012.
