Anti-torsion TPU arch plate provides maximum stability on the trail. Vibram rubber outsole bites into sketchy terrain for great traction and grip. Impact Brake System offers superior grip on very steep terrain; slanted and opposing lugs absorb 20% of the shock on feet, knees, hips, and back while walking on hard ground. * Lightweight, durable, and ergonomically shaped PU/EVA midsole provides excellent support and performance for day hikes and backpacking. Co-molded PU/EVA midsole is supportive and soft to provide stability and shock-absorbing cushion. 7 mm Ergoflex nylon insole provides support underfoot. * Idro-Perwanger rough-out leather and Cordura upper for durability and water repellency. Gore-Tex membrane for waterproof protection and breathable comfort. Ergonomic constructed upper wraps naturally around the foot and works with the shock-absorbing midsole to help reduce negative impact on hard ground. * Soft stretchy Cordura ankle and gusset material minimize top-of-foot pressure points. 3D Flex ankle allows uninhibited maneuverability on technical terrain for greater stability. Rubber rand at toe and heel for protection and durability. * Symbios construction balances protection, comfort, flexibility, and function with an ergonomically shaped PU/EVA midsole and ergonomic last which hugs the foot and provides the best fit possible.
