Product Name : Dr. Martens Store | Mens Dr. Martens 939 Thinsulate Grenade-Green Boots On Sale - Dr. Martens Men Shoes Model : Dr. Martens Men Shoes 323 Get ready for the winter weather: this 939 6-eye boot features Thinsulate lining meant to withstand extreme weather—without any extra bulk. A padded nylon collar keeps the cold out, and the ankle supported, comfortable and toasty on even the coldest days. The 939 6-eye men’s boot is constructed on our iconic air-cushioned sole, that's oil-and-fat resistant with good abrasion and slip resistance—and has been since 1960. This shoe is Goodyear-welted, meaning the upper and sole are sewn together in our heat-sealed z-welt stitch. The boot is made with a combination of New Laredo, a full grain analine leather with a light waxy finish, and extra tough, 100% nylon.
