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 recommend ordering your normal US size.

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.

    Solid boot; unmatched comfort.

    Incredibly comfortable, I’ve been in T brand boots my whole life and my feet always hurt. Gave Lem’s a chance and I’m completely blown away that all boots arent this shape and this comfortable. The almost zero drop is a new concept to me for boots, but making a huge difference in my leg pain.

    One con is, I’m a 13wide. And was expecting a 13 to be perfect since it’s a wide boot and says true to fit. It was much shorter than you’d expect. A 14 was PERFECT. Truly a great fit.

    Another, on the 7th day of wear, the loop behind the boot broke just putting the boots on. Lems says they have a one year warranty on manufacture defects. I’ll update the review when I receive an email back.

    Love my Lems

    Love these boots, I use them for hard work with heavy equipment and have to stand for up to 4-8 hrs a day and have no foot pain and my feet don’t get too hot either, which is a big plus for working in Texas.
