MATERIAL: Durable and famously stiff to start, our Smooth Leather can be polished to a dapper shine or artfully scuffed-up depending on your preference. CONSTRUCTION: This is a Goodyear-welted product. The upper and sole are heat-sealed and sewn together, not merely glued like many footwear constructions. CARE INSTRUCTIONS: Clean away dirt using a damp cloth and allow to dry, then apply Dr. Martens Wonder Balsam, Neutral or coloured wax polish as appropriate, using a Dr. Martens shoe brush, (Neutral can be applied to all colours)
