The GLACIER WLF was designed with input from the guys and gals who get the job done - Rural Volunteer Fire Busters and State and Federal Agencies. GLACIER Wild Land Fire boots exceed minimum height requirements and are built tough - to protect your ankles and feet on rugged, unstable and rocky terrain and also resist heat damage from hot embers. Vibram Ice-New Soles are made from special compound designed to resist 300 C (570 F) temperatures and give serious mountain boot traction. Inside special heat resistant toe and heel counters are employed as well as adhesives that resist 100 C (212 F) degrees temperatures. That said this is not a "front line" boot capable of stepping on fire. Designed for forest management work and post fire clean up. Upper is 3mm Idro-Perwanger rough out leather - the best money can buy - and naturally waterproof and breathable. WLF is fitted with volume adjust Ex Flex tongue and Dry-Best lining for comfort and sweat absorption. 8mm MemFlex and 1.5 mm half steel shank for support, PU Aircushion midsole. 8" tall, ISO 20344 Certified and built to exceed NFPA 1977 Wildland Fire Standards. Available in finely graded Euro sizing for a perfect fit. Shipped anywhere in North America along with a FREE T-Shirt.
