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