Multi-day backpacking treks can be rugged in a couple of ways. First of all, you'll be hiking over peak after peak on rocky summit trails and never-ending downhills. Second, you'll be out in the elements for a few days at a time at the mercy of anything Mother Nature chooses to throw at you. Luckily you'll be ready for all of it when you're rocking the Merrell Phaserbound 2 Tall Waterproof Backpacking Boot. It's got a tough and durable construction for gnarly mountain trails, comfortable support for long daily miles, and a waterproof membrane to ensure that a little rain won't have you swapping out socks every few miles. The M Select Dry membrane is both waterproof and breathable, keeping water out but letting vapor escape so your feet don't end up hot and sweaty despite the waterproofing. Underneath your feet you've got a Vibram Megagrip outsole that offers tough and dependable traction on everything from steep and dusty switchbacks to slippery rock, while the leather upper construction provides all the durability you could need for a summer full of sleeping under the stars.
