The Sierra 9" in jet black by Bonanza is built for tough work where durability, support, and a clean look all matter. The full-grain leather has a rugged base with a more refined finish, so it holds up in harsh conditions while still looking sharp. The taller 9-inch height adds extra ankle support, especially useful on uneven terrain or long, demanding shifts. The unlined interior helps with airflow, keeping things more comfortable over extended wear. Underfoot, the oil and abrasion-resistant outsole provides steady traction, while the 90° heel adds grip and balance on ladders and rough ground. With Goodyear welt construction, it’s made to last through heavy use. The optional steel toe version adds protection when needed without changing the overall feel of the boot. It’s a reliable, work-focused boot that balances strength with everyday comfort.
