The legendary Nike Mag is said to be releasing later this year with functioning power laces. Pricing information isn't available as of yet but it goes without saying that they won't come cheap. For those of you who want a taste but aren't willing to sell your cars for it, Nike's skateboarding division has introduced a pair of SB Dunk Lows inspired by the famed sneakers from Back to the Future Part II. The leather upper is done in the familiar grey and white motif, along with speckled detailing on the midsole and a translucent turquoise outsole. The insole is made to look like Marty McFly's hover board, giving it a nostalgic touch. We'll keep you updated with release details as they come.
