The Rocky Bronco puts the grit in western boots. This 12 square toe boot features waterproof full grain leather and our guaranteed Rocky Waterproof construction creating a moisture barrier so your foot stays dry during the job. Pairing our Rocky Rebound heel with Tpu heel stabilizer, fiberglass shank, and durable ¾ flex welt construction gives this boot a lasting lifetime that can keep up with your workload. Comfort is a priority in the Bronco, so we added an oil and slip resisting rubber outsole and our Rocky Air-Port Lite sponge Pu footbed with memory foam which keeps your feet energized for long days ahead. This boot meets Astm F2892 electrical hazard standard..
