German engineered like no other boot in the world, the Fire Hero® Xtreme boots from HAIX® are designed with the most advanced technology employed today for fighting structural fires. The lower 11" profile allows more freedom of movement for wider calves, while still fulfilling the requirements of a structural firefighting boot. From the profiled rubber toe cap to the large pull on boot straps you have a boot specifically with your safety and comfort in mind. The HAIX® Sun Reflect leather reduces the heating effect of direct sunlight, keeping the leather and your feet cooler. HAIX® Ankle Flex System adjusts the pull on boot to different foot, ankle and heel shapes while ensuring high flexibility when driving the truck or bending and crawling. With a lot of water getting splashed around you'll appreciate the waterproof/breathable CROSSTECH® feature that also offers chemical and bloodborne pathogen protection. Combined with the never duplicated Secura Liner®, you are ensured a liner that will never pull out or wrinkle over time. The uniquely designed rubber nitrile sole comes with a stable non-slipping sole edge for uneven terrain, ice, and snow. The honeycomb tread pattern and yellow suction cups offer excellent traction on slick and wet surfaces. Ladder bar treads in the joint area offers stability on ladder rungs. Soles are also oil and fuel resistant, non-chalky, self cleaning and electrical hazard resistant.. Not only comfortable to wear but easy to take off at the end of the day, too, with the integrated bootjack which is a specially designed lip edge in the rear heel area for easy removal of boots. You never know what is underfoot from broken glass to nails, but with the stainless steel built into the sole, you have ultimate puncture protection. All threads and laces are flame resistant Nomex. Certified to NFPA 1971-2007, NFPA 1992-2005, CAN/CSA Z195-09 and ASTM F2413-05.
