A special nitrile rubber tread to withstand the toughest situations
3Ultra Rubber is a safety shoe designed to withstand the most extreme weather conditions (from -30°C to 300°C) and to provide maximum protection against sharp objects. This level of protection is made possible by a special super-resistant nitrile compound that forms the sole of the shoe. Specifically, the tread features deep lugs designed to grip the ground and provide maximum traction on uneven surfaces. Additionally, the wider spacing between the lugs ensures the sole to be self-cleaning. The side of the shoe, with its attractive design, includes a front overcap that offers maximum protection against hazards found on construction sites. Another strength of this work shoe is the innovative "anti-vibration" sole concept: a combination of technologies that reduce vibrations caused by machinery and moving equipment, minimizing physical stress and wear throughout the day. Finally, the sole is equipped with "ICE GRIP" technology: a series of grooves placed on the sole's lugs that increase traction and help brake the safety shoe on icy or snowy surfaces. The PS-certified puncture-resistant plate also protects the safety shoe from small and dangerous nails.
