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 this boot, and reinforced everything; from a thicker gauge thread to an overall stronger outer construction. 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.

Unsure of your size? We recommend ordering 2+ pairs at a time, as we offer a flat shipping fee of $5.95 & free exchange options for US customers.

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. 


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

    Didn’t work out for me.

    Unfortunately, these boots were just too small for me. I usually wear a size 11 US women’s, I ordered the size 12 US women’s and they’re much too small (they feel more like a size 10 US women’s). I gave them four stars anyway, because I’m sure they’re fine boots when sized correctly.

    Super cute and roomy

    These boots are so dang cute. It is so hard to find cute winter wide toe box, zero drop boots and these fit the bill. They seem sturdy and well made and my toes have plenty of wiggle room, which is great! Customer service is also super awesome!

    They are super stiff around the ankles which I hope loosens up with time. I don’t think I could hike in these without some serious breaking in because of this. They are also incredibly hard to get on. Like I have to unlace the top two holes and it’s still tough and I have narrow feet. The tread is a bit slippery. More like a casual dress shoe.

    These are great day to day shoes though! So happy with my purchase and happy I was able to find these!

    Oh definitely go up a full size when ordering. I sent back twice to adjust sizing and this worked out for me!

    My favorite boot

    These are my absolute favorite boots! A necessity for my job- water resistant yet lightweight, and best of all, my feet don't hurt! I'm SO so sad the Shadow version of these is being discontinued! :( I hope it can come back some day! Their understated, monochromatic appearance even makes them versatile enough for me to wear outside of work. Unfortunately I don't feel that way about the other version of this boot!
