Just this morning, Nike took to Twitter to tease some long-awaited news about the brand's iconic Air MAG silhouette.

Addressed to Michael J. Fox, who of course made the sneaker popular by wearing it in the 1989 sequel to Back to the Future, the tweet simply reads "Excited for tomorrow." It's all but guaranteed to be news about the futuristic kick but what exactly it will be is anyone's guess. It's possible the Swoosh is prepared to present a release date but it's equally likely that we're simply being updated on the shoe's development.

If Nike's original release plan holds, the power-lacing shoes will only be available for purchase via charity auction, with all proceeds going to the Michael J. Fox Foundation for Parkinson's Research. As always, we'll be sure to keep you posted as we hear more.

In any case, the news comes just on the heels of Nike's recent update to the HyperAdapt 1.0.
