Boulder Summit Waterproof

If you’ve been holding your breath for us to release a Boulder Boot style that can properly tackle the trails, you can go ahead and release that breath. Now take another, and another, because you’ll be huffing and puffing up and over mountains and along stretches of dirt and rock in your spiffy Boulder Summit boots. Rain? Mud? Snow? Sleet? No matter, these boots are fully waterproof and will keep those feet dry despite what Mother Nature throws your way.

The Boulder Summit combines the minimalist features of the Boulder Boot with the outsole of the Outlander. This means these boots offer substantial grip without weighing you down, flexibility as you navigate uneven terrain, and the wide toe box means ample space for your toes to spread out fully. The rubber outsole incorporates 4mm deep lugs and zig-zag grooves for superb traction in even the most slippery situations.

Available in Rugged Bark and Coal - a full-grain, oiled leather, which can be reconditioned overtime to retain its best waterproofing - and Nitro - a fully waterproof Nylon and vegan-friendly option.

We find that the Boulder Summit fits true to size, so you can order your normal US size. This is a unisex shoe, so the width is the same for both men's and women's.

As with all Lems shoes, if you need more volume inside the shoe or increased ground contact, you can remove the insole. If you have any questions, feel free to contact our customer service team at elizabeth@etherealwe.com
