Serving as a premium backpacking boot, the Crater Rim’s profile and construction mirror the immensely popular Danner OCH. With outsole and internal materials that reflect the needs of the rugged outdoorsman, this boot was specifically designed to tackle the most challenging terrain. The Vibram Bifida outsole delivers premium traction in the harshest environments, while a polyurethane footbed and Gore‐Tex lining ensure a comfortable and 100% waterproof yet breathable boot.
