This is a Goodyear-welted product. The upper and sole are heat-sealed and sewn together, not merely glued like many footwear constructions.
A full-grain leather with an oily, waxy finish, treated to be water-resistant and have a longer wearing life.
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.
