The Meg Biker Ankle Boot boasts feature linings and an inside zip. It carries a chunky outsole that adds to the premium feel. Features 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. This is a Goodyear-welted product. The upper and sole are sewn together, not merely glued, like many footwear constructions. This, together with the Z welt-stitch and heat-sealing process, makes it unique to Dr. Martens.
