The Sixton Peak Montana from the Endurance collection is a sturdy, comfortable safety boot. The upper of this 81156-05 is made of greased nubuck leather, which has undergone Hydrotech treatment to be extra water-repellent. The inside of the boot has a wool lining, ideal for work in cold weather conditions. The Dual Insulation insole is specially made for winter use and keeps the foot warm and dry. There is also a synthetic anti-perforation midsole to keep sharp objects out. This Montana boot has a safety toe made of metal-free composite. This is light, thermo-insulating and does not conduct electricity, but still offers protection against an impact of up to 200 joules. The SRC standard PU/PU outsole is shock-absorbing and has very good anti-slip properties and stability. Conductive WED strips provide anti-static properties. The crawl toe strengthens the toe of the shoe and protects it against wear. This is particularly useful if work is regularly done where shoes rub against the ground with the toes. This Montana is a completely metal-free boot!
