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.

FULL RUBBER OUTSOLE WITH ZIG-ZAG SIPING

This sticky rubber outsole incorporates 4mm deep lugs for incredible traction on snow, mud, and everywhere in-between! The built in zig-zag grooves (siping) provide additional biting edges to cut into ice/snow and helps ground your feet in slippery situations.

100% WATERPROOF UPPER

With its fully waterproof membrane and gusseted tongue, the Boulder Summit will keep your feet dry and warm, especially after a day on the slopes or slogging through slush on your way to the bar!

ZERO-DROP

Places the forefoot and heel close to the ground correcting posture, aligning your spine, and encouraging mid-foot strike.

WIDE TOE BOX

Unlike traditional footwear that squeeze the toes together, our foot-shaped toe box allows for maximum room giving the toes ultimate freedom to wiggle and spread.

Reviews Summary
Customers say these boots are exceptionally comfortable and require no break-in period. Many appreciate the wide toe box that accommodates natural foot shape and reduces pain. Users report excellent waterproofing and traction in snow, ice, and wet conditions. The boots perform well for various activities including construction work, hiking, and daily wear. Common praise includes their lightweight feel despite being durable work boots. Some mention they run slightly large in sizing. A few customers note difficulty getting them on and off due to the lacing system, and some find the toe box could be even wider. Several users report the boots helped alleviate foot, back, and hip pain.

    My Favorite Boot!

    I’ve always struggled to find hiking boots that remain comfortable, especially as the miles increase on long days. These boots deliver! I just returned from 20 days touring and hiking in Patagonia. I wore these boots every day. They were super comfortable whether traversing the paved streets, riding 8+ hours on a plane or tackling the Laguna de Los Tres (14.5 miles). The boots held up well and remained waterproof through stream crossings, hikes in steady rain and intermittent rain and sea spray on trips in the Magellan Straights. I’m relatively new to LEMS and bought these earlier this year. I tested these boots rucking(40 lb pack) and on some of the lower elevation trails during the first months of 2026. I do wish this waterproof version was available with the vibram sole however I’ll continue wearing and testing to see how the current sole performs. So very happy I found LEMs and this model boot.

    Amazing Look, Fit, and Feel

    I’m always skeptical about buying shoes online but got a good recommendation from a friend. I took a gamble and it paid off.

    They were a bit tight around the mid because I got wide hobbit feet but I knew they would break in. Once they did, it was like the shoe was meant for my feet. I love the wide toe box. The soles feels great as I walk. The transition from tradition shoe to zero drop was good and painless. I’m doing six miles rucks on them and my feet feel great so far.

    Please, please, please do not change or discontinue this product! It’s one of the best shoes I’ve ever put on my feet.

    Good shoe

    Very comfortable from day 1. I've hiked in them on some very difficult trails. Great traction even on wet rocks and roots. Stayed dry wading through puddles and shallow streams.

    Will have to see how durable they are over time.

    My only complaint so far is the outer leather has a suede like texture, so they hold dirt and look dirty all the time.
