100% leather upper. 60% leather and 40% textile inner. Two-tone finish. Double height Bex outsole with a rugged commando tread pattern for traction. Goodyear-Welted for comfort and durability. Signature welt stitch. A contemporary penny loafer silhouette, the Penton by Dr. Martens is built on the brand’s double height Bex outsole, marked distinctly by the signature DM yellow welt stitch. This particular pair is crafted from Quilon leather in England at Doc’s original Wollaston factory, showcasing a vintage look and two-tone appearance. Goodyear-Welted, the upper and sole of the Penton are sewn together for added durability, instead of being glued together like many other footwear silhouettes.
