The Sixton Peak Montana from the Endurance collection is a sturdy, comfortable safety boot. The upper of this 81156-00 is made of full-grain leather, which has been treated with Hydrotech technology to be extra water-repellent. No liner or HDry membrane has been installed. An anti-perforation midsole keeps sharp objects out. The Dual Insulation insole is specially made for winter use and provides extra insulation. This keeps the foot warm and dry. Dynamic HC control and Stabil Active keep the heel in the correct position, provide support to the heel and arch and control the lateral movement of the ankle. The safety toe is made of ultra-light metal-free composite; thermo-insulating and does not conduct electricity, but still offers protection against an impact of up to 200 joules. The PU/PU outsole is shock-absorbing and, with its SRC standard, offers excellent stability and anti-slip. Conductive WED strips give this shoe anti-static properties. The crawl toe significantly increases the wear resistance of the toe of the shoe. This is particularly useful if work is regularly done where the nose rubs against the ground. Every Montana is metal-free!
