The KARNAK 222BV-05 HI HRO S3 SRC is a premium safety boot engineered for demanding work environments, fully compliant with Standard EN ISO 20345:2011.
The upper features a high-performance tight-knit three-dimensional textile structure that ensures exceptional breathability while keeping feet dry, along with reflective material for added visibility and an SBX TPU stabilizer designed to support the ankle and maintain perfect balance during movement.
At the core is the Esolight 1.0 polyurethane midsole, crafted from low-density micro-cells that enhance energy absorption and promote correct body weight distribution throughout the workday.
Protection is delivered by the PZ88 steel toe cap, rated at 200 Joules, paired with a perforation-resistant Txzero textile insole that combines lightness, flexibility, and outstanding protection. The T-01 anatomic insole adds extra comfort with supporting PU foam for energy return and a micro-perforated conductive lining to minimize foam wear.
The ICON two-component PU-RUBBER VIBRAM® outsole provides maximum grip and stability on uneven and slippery surfaces — slip-resistance tested by SATRA laboratories on metal grating and wooden scaffold boards. It is also HRO heat-resistant, fuel oil resistant, self-cleaning, and offers a wide fit for superior stability.
