Although these don't come with all the bells and whistles that you'll find on the Nike pair, they can be had for literally a fraction of the going rate for the real deal. What's more is they can be "upgraded" with custom kits available on eBay that will bring these even closer to the authentic aesthetic. When it comes to grail-level sneakers like the Mag, sometimes you just have to fake it 'till you make it.
Priced at $99, these replica Mags are probably as close as you'll come to the Marty McFly look without breaking the bank in the process. Head over to HalloweenCostumes.com now to place an order, but don't snooze, because these won't last long at all.
