The Nike Mag is now officially for sale, hitting eBay for a special auction to benefit the Michael J Fox Foundation. Accompanying the release is this amazing commercial, paying homage to the Back to the Future series, and in fact featuring original cast members Christopher Lloyd (Doc) and Donald Fullilove (Goldie), while tying it together with the modern Nike era with guest spots from Kevin Durant and Tinker Hatfield. And SNLer Bill Hader appears, to boot. So hit the jump and give it a watch, well worth two minutes, then try to list all the BTTF references. And make sure to check out Michael J Fox on Letterman tonight, most likely talking about the shoe.
