So Michael J. Fox teamed up with the NIKE company to create the fictional shoe from "Back to the Future II", the Nike Mag. Those light up, light material wearing sneakers.

Now in the trailer they have Christopher Lloyd show up as Doc in his outfit from that movie looking for shoes haha. Check it out:

The shoe was made and is being auctioned off ebay. They made 1500 pairs of these shoes! They are not cheap, but ALL the proceeds go to Michael J. Fox's charity to help research for Parkinson's disease and to finally find a cure to rid it. One of the coolest and smartest charities.

Also don't forget to check out the auction page for the shoes: NikeMag Back to the Future
