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 waterproof boots are incredibly comfortable right out of the box with zero break-in time needed. The wide toe box accommodates various foot shapes, including those with bunions or wide feet, while providing excellent ankle support. Users report the boots perform exceptionally well in wet conditions, keeping feet completely dry through rain, snow, and creek crossings. Many mention the flexible sole allows natural foot movement while still offering protection from rocks and nails. The aggressive tread provides excellent grip on various terrains from city streets to mountain trails. Several customers note the boots are lightweight yet durable, with some using them for demanding work environments. A few mention the laces could be longer and some experience minor rubbing from tongue seams.

    Ready For Iceland

    My wife grabbed these for our upcoming trip to Iceland on the recommendation of friends.

    Stylish without the clunkiness of typical hiking boots.

    She's been wearing them to "break them in", but that wasn't needed.

    Very comfortable toe box.

    Two thumbs up!!

    The exact long-distance walking shoes I needed

    Bought these for a 2-week trip to the UK, didn't have to spend any time breaking them in which was amazing. I immediately was able to wear them for 5-10+ miles of walking (cobblestone, pavement, through museums, up & down historic outdoor sites), over 5 days in a row - with no lower back pain (something I normally get when walking longer distances) or blisters, discomfort, etc. Super light, super comfy, highly recommend! I intentionally got a half size bigger than I probably needed (wanted to make sure there was room for thicker socks), but wearing two pairs of socks at a time made it a non-issue.

    Outstanding Performance

    I wear barefoot shoes. I needed some boots for a trip to Scotland. After a lot of research over a wide variety of companies I decided on the Summit Waterproof boot. I even ordered a Vivobarefoot boot so I could feel them side by side. I stuck within the Lems. For 8 days I hiked in the highlands through mud and water and then the hilly city of Edinburgh. I went a total of 51 miles in my Lems throughout the week. I didn’t break them in before and I still didn’t get a single blister. We didn’t get as much rain as anticipated but when there was, my feet were comfortable and dry the whole time. These boots were my best purchase for the trip. I can’t say enough good things about them. I wear a 9.5 in non-barefoot shoes and my feet are about 25.5 in. For most barefoot brands I wear a 10. I ordered a 10 in these and they fit perfect, still plenty of room for toe splay even with wool socks. I highly recommend these boots!

    10/10

    I have painful bunions, so I usually treat new shoes like enemies. But these? Absolute champions.

    i wore the Lems Boulder Summit Waterproof all over Japan and walked up to 36,000 steps a day without pain. I only brought this one pair, and they somehow handled snow, miles of walking, and dressing up for dinner. They’re also super spacious, which my bunions greatly appreciate.
