The Made In England Collection styles are handcrafted in the original factory in Northamptonshire by cobblers using the original construction techniques. The 3-eye Steed oxford uses a slim last and a plain welt. Crafted with Polished Smooth Leather with an internal leather lining. Made with Goodyear welt, the upper and sole are heat-sealed and sewn together, like many footwear constructions. This, together with our Z welt-stitch and heat-sealing process, makes it unique. Dr. Martens have an air-cushioned sole, are oil and fat resistant and offer good abrasion and slip resistance. Material A twist on the classic Dr. Martens leather: durable, with a smooth and polished finish. Care Instructions [Smooth] = Clean Away dirt using a damp cloth, allow to dry apply correct coloured wax based shoe polish to restore shine as desired. Construction This is a Goodyear-welted product. The upper and sole are heat-sealed and sewn together, not merely glued like many footwear constructions.
