Mark McNairy's New Amsterdam fall/winter 2011 collection includes this sick One Piece Derby ($340). The grain leather derby is literally one-piece of leather with no visible stitching on a  Dainite commando sole, and the less the details, in this case, the better the outcome. Coming in brown or black, these limited babies are popping up at select McNairy stockists, including Triads in UK. [Slamxhype]
