One of the major highlights in the Spring/Summer 2012 footwear releases would be the Alexander McQueen and PUMA collaboration on the latest Street Climb Mid made from calfskin leather. In par with the fabric-based Street Climb Mid releases, this pair features unique midsole markings toward the toe, understated perforations in the interior leather lining of each iteration, brushed metal lace hardware and a matching tongue clasp to finish it off.
