Built to combat the elements and the asphalt, the Alcan™ boot is ready for the harshest of ADV use. The upper is comprised of TechTuff leather, renowned for its durability. The reinforced shin plate provides cover for the BOA® lacing system for optimized fit. A waterproof/breathable liner keeps the interior dry while D3O® ankle inserts provide increased coverage. The outsole is a combined construction of internal reinforced shank, hi-rebound foam cushioning, and an oil & slip resistant rubber bottom unit.
