The SL M3 Boot by Scarpa is their premier backpacking boot. Recommended by NOLS, and just about every guiding service you'll sign up for, the SL M3 sets the standard for durability and stability; whether you are doing a long trail, carrying a heavy load, or hiking in rough terrain, you should consider the SL M3.
Its silicone-impregnated leather uppers stand up against the most abusive trails while they give you water protection for wet-weather hikes. Scarpa added articulated cuffs to increase flexibility while still giving you the support you expect from leather boots. Vibram M3 outsoles increase the SL M3 Backpacking Boots' traction on steep, rough, slippery trails, so you stay on your feet and continue your hike with ease."
