NEW WITH TAGS AND ORIGINAL BOX MSRP $355 Porsche Design Driver Black Calf Grain Leather Moccasins US 8.5. Based on the legendary Beverly Hills moccasin, the Porsche Design Driver Calf Grain provides maximum comfort and on-road agility. The technically inspired bar references the vents on the Porsche 911 and contrasts with the natural beauty of full-grain leather and traditional hand-stitching on the seams. The upward curve of the heel protects the leather upper while driving. The footbed features arch support. An exclusive Porsche Design anti-slip sole gives you a skilled grip on the gas pedal. One eye-catching detail never ceases to delight: the shimming material on the sole that calls to mind hot asphalt on the track, for a great start to every trip – even before you switch on the engine.
