The monochrome 'toe to tip', inspired by Dr. Martens, that has been lovingly burnished so often that the polish has worked its way into the actual sole. The sole, welt, stitch, eyelets, laces, back loops and even linings are identical colors. Made on their '84 Last which is a sleek and tapered fit made of smooth leather, Airwair's original signature leather: a firm, finished leather with a smooth and semi bright appearance. This is a Goodyear-welted product. The upper and sole are heat-sealed and sewn together, not merely glued like many footwear constructions. Dr. Martens Size Chart (orders placed in UK sizes): Upper: Smooth Leather This style tends to run large. For an accurate fit we recommend purchasing a 1/2 size smaller than you typically purchase. For example, if you normally purchase a size 7 1/2, we recommend purchasing a size 7.
