Whatever the day brings, Basalt helps get the job done. As the successor to the Volcano, this S3 safety boot is solidly built and features several enhanced characteristics, including an improved PU rubber outsole. The shoe is designed for tough working conditions where perfect protection, stability, and ESD, metal-free, as well as heat-resistant requirements are needed. Thanks to the pull-up leather upper and membrane lining, the Basalt is completely waterproof while remaining breathable. This makes it the ideal choice for anyone looking for an all-around outdoor safety shoe.
