This season, we added brogue styling and a kiltie, and totally transformed the Chelsea into a uncompromisingly fashion-forward statement boot. It's made with Polished Smooth, a classic Dr. Martens leather: durable, with a smooth finish that's polished to a higher shine. The Tina Brogue Chelsea women's boot is constructed on our iconic air-cushioned sole, that's oil-and-fat resistant with good abrasion and slip resistance - and has been since 1960. This boot is Goodyear-welted, meaning the upper and sole are sewn together in our heat-sealed z-welt stitch. Material: Leather.
