What Our Gearhead(R) Experts Are Saying: "I've taken the TPS 520 GV Evo on some seriously demanding treks, and it never lets me down. The full leather upper breaks in beautifully and offers solid protection, and that Vibram sole with built-in shock absorption is clutch when I'm carrying a heavy pack over rocky terrain." We count on the Asolo TPS 520 GV Evo Backpacking Boot for long-haul missions deep into the wilderness, especially when the trail gets rough and the miles stretch long. This serious backpacking boot is built from a single piece of water-resistant full-grain leather that resists wear and delivers long-lasting protection. Backed by a Gore-Tex Performance Comfort membrane, it seals out moisture while still breathing-ideal for alpine storms and humid valleys alike. Underfoot, the TPS 520 GV Evo balances support and comfort with a co-injected dual-density polyurethane midsole, softening each step while keeping our stride stable on tricky traverses. The Triple Power Structure outsole, developed with Vibram, uses three shock absorbers in high-impact zones and features a self-cleaning tread for dependable grip across technical terrain. Finished with a Micro Pully lacing system and a tried-and-true backpacker fit, this boot is built for remote trails, heavy packs, and multi-day performance.
