SIZE CHART | PRINTABLE SIZE GUIDE |
SIZING NOTES: Fit is small. Most people order 1/2 size or 1 size larger than their normal US Size.
Weighing a mere 227g (Mens size 10), the Boulder Boot is arguably the lightest boot in the world.
Maybe you’re already familiar with our groundbreaking (not literally, we love nature) Boulder Boot, but if you’re not, this new version will blow your socks off (again, not literally). Complete with every feature you love, this is like the footwear equivalent of the convertible version of your favorite car.
JUST A LITTLE BIT OFF THE TOP
Our original Boulder Boots have long-held the title of most packable boot, but there’s a new boot in town and it might just be coming for that title. This ultimate outdoor boot has the lightweight outsole, the wide toe box, and are obviously zero-drop, but, because we took a little off the top, are even easier to throw in your backpack before hitting the road. Truly, what’s not to love?
Before we put a cork in it, we also wanted to mention that these low-riders are the first pair we’ve used cork in. By adding an ultra-thin 0.8mm cork top layer, your foot will be feeling the benefits of natural coolness and comfort, with or without socks. Cork also molds to your foot giving you the ultimate perfect fit. So, if all that wasn’t great enough, we also want to mention that cork is fully sustainable—which is great because Lems is all about keeping it as green as possible these days.

CORK FOOTBED
By adding an ultra-thin 0.8mm cork top layer, your foot will be feeling the benefits of natural coolness and comfort, with or without socks.

IBR OUTSOLE
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.

ZERO-DROP
Places the forefoot and heel flat 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.

I wish I had bought a pair years ago! I was nervous choosing a size, but I had help from BPrimal and they fit really comfortably. I went for a big walk the other day and it was the first time my feet didn't hurt.

Straight out of the box these were most comfortable boots ever

I absolutely love my waterproof boulder boots, so bought these knowing the fit and comfort would be the same. I was right, they are super comfy, light weight and a great all-rounder. Now Lems, please make these in a black leather. Like with my other boulder boots, these can be worn all day, every day and they feel amazing
