That even extends to the most iconic 3-eye shoe, the 1461, which gets a seasonal update in soft Aniline full grain smooth leather with treated in the final stages of shoemaking to give it a classic, hand antiqued finish. Reinvented range takes classic Dr. Martens styles and customizes them, playing with their history to create something new every season. This is a Goodyear-welted product using PVC for the welt. The upper and sole are sewn together, not merely glued, like many footwear constructions. This, together with our Z welt-stitch and heat-sealing process, makes it unique to Dr. Martens. This is the only construction that is stitched on the outside and helps footwear take the shape to the foot. The welt is chain stitched to the upper and insole. The outsole is then sewn to the welt around the edge and then heat sealed. This is the sturdiest and most complex of all constructions. This sole is hard-wearing, with good abrasion and slip resistance. Material: Leather.
