The STAN S3 HI fire-resistant safety boot offers particularly good protection due to the S3 safety standard. But this safety boot has more to offer than that. The upper material is made of fire-resistant cowhide leather and is finished with heat-resistant seams. As a result, this boot offers protection against splashes of molten iron and aluminium. Besides the steel toecap and metal-free midsole, the STAN S3 HI has a coarsely profiled non-slip rubber sole that is heat-resistant up to 200°C and can briefly protect against temperatures up to 300°C. The quick-release fastening on the shaft can be adjusted to the wearer's preference. The safety boot is approved for orthopaedic adjustments according to EN ISO 20345 (DGUV 112-191).
