Developed and designed for the serious rider, the Quadrant Boot redefines what performance is all about. With class leading features like our pre-curved shin plate, and action-pivot buckle bases, no other boot comes close. This year we've improved the boot even further by adding aluminum buckles and refining the sole curvature for improved performance. "Action-pivot" buckle system which ensures a secure fit and proper alignment with the closure straps. Elastic gaitor keeps out dirt and debris. Pre-curved injection molded shin. Split grain leather heat shield provides protection and comfort. Adjustable positive-lock buckles feature an action-pivot base. Injection molded medial abrasion plate with integrated shift protector. Unidirectional outsole with steel shank insert. Genuine split grain leather construction.
