Are you a runner? Happen to have any old running shoes in your closet?

If so, you may be interested in Dave Russell's story. He just got $50,000 for these "funky, old shoes" that happened to be a pair of extremely rare prototype Nike running shoes from 1972 (only 10 were given out).

Dave said, "They were very exotic because the sole was completely different. It was made on a waffle iron. It was glued to the bottom of the shoe."

He said the shoes spent years in a box in his garage, next to the Christmas lights. He only decided to sell them a few months ago, and received an offer from The Graduate Eugene Hotel, which is building a Nike museum in Eugene.

Got any old funky sneakers you want to get rid of?
