The Les boot takes the classic Dr. Martens 7 eye boot silhouette, and makes it clean, feminine and modern. How? They give it a lightweight sole, with a specialized Ranil compound. With a contrast sole, a subtle wedge heel and three additional tunnel loops. On top of that, Dr. Martens winterized the boot, lining it with soft, rich artificial fur. The Les Fur Lined boot is made with Burnished Wyoming, a leather with a subtle grain and an oily surfaced, that's been treated for an antiqued look. It has all the DNA of a classic Doc - it's Goodyear welted, meaning the upper and sole are sewn together in a heat-sealed z-welt stitch for enhanced comfort, but uses a compound called Ranil. That, along with its design, is why it's so lightweight. Material: Leather.
