The Heritage Chukka Work Boot was made and inspired by the work shoes worn by carpenters, mechanics, wood workers, and engineers. The 520 Pro features a durable heavy-duty polyurethane sole offering shock absorption, tread, comfort, and dependable performance. The outsole material is designed with tiny micro air bubbles to relieve heavy pressure when your feet put through tough movement during work. Unlike most chukka boots, the 520 features 3 nickle plated eyelets for strong and tightly secured lacing. The insole has a cushion pillow comfort for arch support. With a strong oil full grain upper leather for durability and soft pigskin lining for comfort, this well-developed work shoe fits both work and casual. As with all our Golden Fox shoes this boot has a classic Goodyear Welt construction stitched to its upper allowing for maximum durability and resole-able capabilities.
