Here's a couple of pics of an upcoming Nike SB Dunk Hi that have recently leaked online. I find a lot of SB's hit and miss, but recently they've been on point with the colourways and materials. Featuring an all black leather upper, a leather tongue and a black suede swoosh, this SB Dunk features "all black everything". No Jay-Z.
Release date is unknown, but I'm pretty sure we can expect these to drop by Spring 2011.
