Last October, Nike and Michael J. Fox unveiled a functional power-lacing Nike Mag, the space-age sneaker first seen Back To The Future II. The unveiling was accompanied by the news that Nike would release a limited number of the self-lacing Mag through a charity auction in Spring 2016. While that launch window has come and gone, it would appear that Nike hasn't forgotten its promise, as it sent out a tweet today to Michael J. Fox that simply read "Excited For Tomorrow." Stay tuned.
