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 usual EU size.

If you’re unsure, please use the cm guide above.

Important: the insole length should be slightly longer than your foot — around 1 cm of extra space for natural movement.

For example: If your foot measures 25 cm, choose an insole length of approximately 26 cm.

FULL RUBBER OUTSOLE WITH ZIG-ZAG SIPING

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.

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.

    Life Changing

    I bought these boots because a friend recommended them.

    Having wide feet and bunions, I have always had foot pain when wearing shoes.

    After purchasing these and several other pairs of Lems, the of health of my feet has transformed

    I'm pain free and my feet have become so strong.

    I will be repurchasing for life.

    Thank you for giving me my quality of life back.

    Amazing shoes

    These are THE shoes.

    I’ve had them for close to 3 months now, they are incredibly comfortable and sturdy. I’ve put their waterproof claim to the test, and I’m happy to report that despite the current floods where I live, my feet are dry and warm!

    I’ve tried a lot of barefoot shoes to go on adventures with my dogs, and none really survived more than 2 weeks nor were they really waterproof.

    The Lem’s are worth their price so far!

    Finally, the shoe that can do it all!

    I don’t know why I waited so long to try Lems. I’ve been running in Altra’s for years. My feet are happiest in a zero drop and wide toe box but Altra’s are so ugly I could never pull them off with a pair of jeans and a cute top. I have an upcoming trip to Europe where I plan on walking 12+ miles a day site seeing, thus my research for the one shoe that can do it all started and I stumbled upon Lems. This is the superior boot, sleek black, waterproof rugged and looks cute with jeans. I will be buying the brown pair soon! They are also true to size. Perfect!
