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 - 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 WIDE 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.

    Lightweight with Great Ankle Support

    I'm so excited about these boots. I have trouble with rolling my ankles and I am thrilled at how "stiff" the ankle support is while the boots are still super lightweight with lots of room for my toes to spread out.

    Women's Boulder Summit

    I normally hike in Keenes and wear custom orthotics. My orthotics don't fit well in the my new Lem's Hikers. I am not sure I can hike in the Lems shoes due to orthopedic surgery I have had on my left ankle. I need the support of the orthotic to tackle hiking with vertical gain. I still love my other Lem styles and I haven't given up on my new Lems hiking boots but I think I will have take trail hikes easy until I see how I do in them.

    Found my "forever" boot

    I can't decide what impresses me most about these boots. They are so comfortable that I want to wear them daily. The look good enough that I don't mind throwing them on with a good outfit. After a wet weekend in the mountains with shockingly dry feet, good grip, and a startling lack of mud tracked into the truck, I am officially sold on them. I have loved them for day hikes for months but after spending the weekend in them I can say that they are now my best boots. I can't believe how dry and clean they stayed. The tread is grippy and durable on and off the trails. I was worried about the durability of the tread after my primal zens didn't hold up but the Boulder summits have been fantastic. I can't recommend these enough.
