In the movie Back To The Future Part 2, Marty and Doc travel to the year 2015. Just a few years before they arrive, it looks like some of the technology we saw in the movie is becoming reality.
For example, Nike auctioned of 150 pair of it's Air Mag in 2011 with proceeds going to the Michael J. Fox Foundation. If you have a pair of those shoes from the future, now you can buy a hoverboard to go with it.
