Dr. Martens Made in England Pascal uses a high shine, superior quality Portuguese Boanil Brush Leather. This rub-off leather has a natural backing with the appearance of traditional non-dyed leather. The boot is made in Dr. Martens' original Northamptonshire factory by hand, including hand-polishing. The style also uses a slim last and plain PVC welt. Made with Goodyear welt, the upper and sole are heat-sealed and sewn together, not merely glued, 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.
