Story A waterproof, featherlight boot to move fast in the mountains The Waterproof Boulder Summit Boot takes the best of Lems’ signature Boulder Boot and pairs it with the rugged reinforcements of the Outlander. This zero-drop boot features a leather and nylon upper, as well as a waterproof membrane to keep your feet dry in the wettest conditions. It comes in at a featherlight 14.8 oz.—thanks in large part to the air-injected outsole—and is pliable while still providing enough support to keep up in the mountains. To top it off, it also has a removable insole in case you want to swap in custom inserts.
