Some boots look great with semi-formal clothing. Some are capable on the trail. Danner's Mountain Light is both. Seen in a black-over-brown colorway, it offers a one-piece full-grain leather upper lined in Gore-Tex to protect against water intrusion. That sits atop a fiberglass shank, with a military-inspired Vibram Kletterlift lugged outsole for outstanding traction, on the curb or on the trail.
