The Bonny unisex boot was created to withstand any weather or terrain with serious style. Made with a military-esque waxed canvas and extra-tough nylon paneling, the Bonny is a chukka style that's rugged, durable yet lightweight. Best of all, it retains all the DNA of a classic Docâincluding stitching and signature loop. The Bonny is extra comfortable, with a large, chunky Dr. Martens air-cushioned sole that's oil and fat-resistant, with good abrasion and slip resistance. The Bonny also has a more lightweight soleâthat's cemented, and non-welted. The Bonny unisex Chukka boot is made with 16 oz. waxy Canvasâa traditional weave canvasâand extra tough 100% nylon. Material: Canvas, Nylon.
