What Our Gearhead(R) Experts Are Saying: "I've worn these boots on long alpine approaches and multi-day treks-they're bombproof. The leather upper breaks in beautifully, the Vibram sole grips on sketchy terrain, and the dual-density midsole keeps things comfortable even with a loaded pack." The Asolo TPS 520 GV Evo Backpacking Boot is built to handle long miles, technical terrain, and unpredictable conditions without sacrificing comfort. Crafted from a single piece of water-resistant full-grain leather, this boot offers superior durability and protection. Inside, a Gore-Tex Performance Comfort lining guarantees waterproof breathability, keeping our feet dry on river crossings and through sudden storms. Underfoot, the two-density polyurethane midsole offers long-lasting cushioning and support for extended treks. The Asolo/Vibram Triple Power Structure Evo outsole features three targeted shock absorbers, delivering grip and stability across varied terrain-from alpine rock to forest floor. A Micro Pulley System makes lace-up fast and precise, locking in a secure, customized fit that holds up for long-haul travel and technical backpacking.
