The durable Alderton men's boot takes all the style of our classic Church Monkey boot, and revolutionizes it with a rugged, utilitarian outsole. With a padded collar and twin ski hooks, your boot will be secure, comfortableâand ready for a muddy adventure. The Alderton men's boot is constructed on Dr. Martens air-cushioned soles, that are oil-and-fat resistant with good abrasion and slip resistanceâand have been since 1960. Durable and solid, the boot is Goodyear welted, meaning the upper and sole are sewn together in a heat-sealed z-welt stitch for enhanced comfort. Classic Doc DNA comes in the form of yellow contrast stitching. Finally, the Alderton comes in Kingdom, a soft, waxy leather with oily finish. Material: Leather.
