Dr. Martens Women's Marine Oxford 100% Leather Synthetic sole This is our classic McMartens tartan fabric, combined with a classic black patent leather. This is a Goodyear-welted product. The upper and sole are sewn together, not merely glued, like many footwear constructions. This, together with our Z welt-stitch and heat-sealing process, makes it unique to Dr. Martens. The original Dr. Martens air-cushioned sole, providing underfoot comfort and durability since 1960. It is oil- and fat-resistant, tough and offers good abrasion and slip resistance.
