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.

This shoe is available in only one width. It is built on our WIDEST Natural-Shape Last. (see image below)



This brand new, 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.


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!


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


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.

    The perfect boot

    I've been waiting for these boots. These are my new work wear. I'm so excited to have well fitting shoes that feel comfortable all day. This is my 3rd pair of Lems, and probably my favourite. No complaints at all. Highly reccomend.

    My favorite pair of LEMS!

    This is my 4th pair of LEMS and they are my fav!!! Fits true to size, love the thicker insole and super grippy outsole.

    So comfy!

    These boots are as comfortable as slipping into your sweat pants at the end of the day. Love the look and feel. I ordered a half size over what I sometimes do based on my Drifters size of 10.5 and could probably have stayed at a 10, but I'm okay with more room rather than a tighter fit. I only have one suggestion and that is to exchange hooks for the top two or three eyelets, allowing easier on and off. I've really never had a bad experience with Lems, and since finding them, I have ordered multiple styles. I have very picky feet. A neuroma on one, cheilectomy on the other as well as a middle tow bone spur. Above all else, I have bad knees so I need a low or zero rise shoe to help make those feel SO much better. So glad I found Lems! Xero's are good too, but I prefer my Lems. PS. If you love Lems, you owe it to yourself to have a pair of Drifters. Just sayin'. My favorite every day shoe. But, I'll be wearing these Summit's a ton too!
