The Waterproof Boulder Boot has long been our most requested shoe, and we’re confident that they’ll be worth the wait. Speaking of weight, this boot still maintains the lightweight frame you’ve come to know and love from Lems — even though we’ve added a unique waterproof membrane, these puppies will still hit the scale at a featherlight 12.9oz. 

We also took some time to rethink the overall construction of our latest release, and reinforced everything; from a thicker gauge thread to an overall stronger outer construction, this is our toughest pair yet. And yes, before you ask, they’re zero-drop. Ready to roll through a river, plow through an ice pack, or anything else on your agenda? Good, because so are our Waterproof Boulder Boots, which keep your feet shockingly clear from clammy conditions due to a breathable waterproof membrane that stops water from penetrating into the boot, while still allowing the heat from your feet to escape. This kind-of-a-big-deal boot also utilizes a pre-treated leather upper, that can be reapplied with waterproofing wax/spray to help extend its water repellency.

The Waterproof Boulder Boot is the one shoe that does it all without ever missing a step. You can easily pack it, but you’ll also feel good wearing it everywhere, everyday. And just so you know — this boot was designed with an incredible amount of detail and care, and we can’t wait to see where you go in it.

We recommend ordering UP 1/2 size from your normal US size. If you plan to wear a thicker sock, consider a full size up.

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


Rain or sun, we’re ready. Not only can you skip along streams and keep your toes dry, you can up the ante on where your travel takes you this winter, thanks to your new favorite pair, complete with a gusseted tongue.  


We’ve utilized a 100% full-grain leather with an oiled finish, that is pre-treated to be water repellent. To increase the water-repellency and extend it over the life of the shoe, we suggest using a waterproofing wax such as Otter Wax and reapplying 2-3 times per year.


Our injection blown rubber outsole is what makes Lems incredibly lightweight and flexible. Deemed as the perfect travel companion, this boot can pack down to the size of your favorite puff jacket. 


These everyday shoes are some of the lightest on the market. You might be tempted to think you’re not wearing shoes at all, but don’t be fooled; we’ve got your feet covered. 


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


Whether you prefer your laces loose, or tied up tight, thanks to the gusseted tongue you’ll always be protected from the elements.

    Almost PERFECT!

    I got a half size up from what I normally wear and these were a perfect fit right out of the box and super comfy. I've been wearing them for 7 months almost every day and they've held up wonderfully. I only really wear them for work, but I walk miles every day in a huge warehouse and they're exposed to all kinds of dust and grime from working in maintenance. I have taken them out in the woods before and they are very waterproof but completely lacking tread. I managed, but I felt like I could slip at any second. They're super lightweight, thus easy to pack and not a burden to wear. I love them so much I was super stoked to hear about the Boulder Summit! I already bought a pair of them and I'm so excited!

    Nice boots

    Bought them for my wife and she loves them. Just make sure you order 1/2 size up didn’t read the size guild and had to exchange them for a 1/2 size bigger.

    Everything they claim to be

    I’ve been watching these boots for years, waffling about whether they were what I actually needed, and how often I would wear them. I finally got a pair, and after spending a weekend walking through a semi-flooded city in the wake of tropical cyclone Ophelia, I can say that they are just as comfortable and waterproof as they claim to be. Perfect comfortable and straight out of the box, with almost 10 miles of walking the first day, and no hotspots at all.

    Only complaint: I would say that the treads are not great on slippery surfaces, and would consider their more rugged-soled model, but I did not like the colors available.
