The TRX 17" Insulated Boot offers 100% waterproofing and features a 5mm Neoprene boot for flexibility and warmth. It's designed for easy on and off, with a roll-down calf pipe for tucking in pants or ventilation in warm weather. The boot provides great traction in various weather conditions, thanks to its slip-resistant rubber outsole with a rugged all-terrain tread. The rubber is made from natural vulcanized rubber, making it ozone resistant and anti-aging. Inside, there's an EVA insole for lightweight cushioning and comfort during hikes, complemented by a 4-inch steel shank in the footbed for added stiffness. The boot is comfort-rated from -70 to 30 degrees Fahrenheit, ensuring versatility in extreme temperatures.
