Finding boots that are ultra-minimalist, featuring a wide toebox, lightweight form and zero-drop design doesn't need to be difficult!
If you loved the incredibly good looking Leather Boulder Boot, have we got something exciting for you. The upgraded version is made with all the features you know and love, like supreme flexibility, a zero-drop platform, and unparalleled packability, but now, it’s also waterproof! That’s right, you can dive right into your next adventure while keeping your feet fully dry.
This boot still maintains the lightweight frame you’ve come to know and love from Lems — even though they have added a unique waterproof membrane, these puppies still hit the scale at a featherlight 365gm.
They also took some time to rethink the overall construction of the boot, and reinforced everything; from a thicker gauge thread to an overall stronger outer construction, this is the 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 the 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.

Lems - Waterproof Boulder Boot - Shadow (Unisex)
A few months ago I bought a pair of these for myself - they are SO comfortable and light to wear (having previously been a DM and Blundstone fan). This pair I bought for my son. The only thing that both of us have found is that it is vitally important to check the size. I have a 25.3 cm foot and find the Men's 9.5/Women's 11 for a 27.3 cm foot fit well. My son has a 28cm foot and is wearing the Men's 12.5/Women's 14 for a 30 cm foot. Both of us wear them without socks. Both of us find them tight to get on (we must have wide feet). the tightest part for both of us is at the bottom of the lacing (I think it is called the 'throat'). I own a pair of Chukkas and find them to be the same. Having said that, once on they are wonderful: light, wide in the toe, no rubbing, keep our feet warm and dry on these frosty mornings. We both walk barefoot around the house and these are the only shoes we possess.

The best boots ever!
The comfort of these boots cannot be matched. I have total comfort, support and warmth with these boots and my feet do not hurt at all from being on them all day. I have two pairs of boots and three other pairs of LEMS. Best shoes ever!

Top Notch Walking Boot
These boots are fantastic, feel great on my feet, flexible, light and the waterproofing holds up. Printing the size guide to figure out your size is worth it. The only disappointment is that one of the shoelace tabs in the middle of the tongue broke in the first week while trying to lace them tightly. Still wearing these everywhere happily.
