The Gauge BOA® combines cycling-specific features, like clipless pedal compatibility and supportive fit, with the reliable grip of an aggressively lugged rubber outsole and the feel of a trail running shoe. The BOA® Fit System provides a mircoadjustable, precision fit, while reinforced heel and toe boxes offer protection from scrapes and impacts. With an upper made from supple synthetic fiber and breathable mesh and a stout injected-nylon inner shank to help transfer your power to the pedals, it gives you the confidence to take on any trail.
