This 16 inch black heavy duty full-grain leather upper engineer biker boot is tough enough to protect against a harsh work environment and classy enough to convey status. A split shaft and two adjustable straps with buckle closures allow for a tailored fit at the calf. Another plus is the Goodyear welt construction that ensures durability.
