The self-tying Nike MAG is finally here 26 years after they were first conceived in Back to the Future II, and to announce the official beginning of the future, Michael J. Fox debuted the sneaker’s power laces on Jimmy Kimmel Live tonight.

Fox Foundation. Without further ado, check out the videos below.
