Lems Boulder Boot Review

Lems Boulder Boot Overview

Lems Boulder Boots are versatile, lightweight travel shoes that excel as casual urban footwear and hold up well against the rigors of the trail. They’re also incredibly packable. Whereas most boots take up as much storage space as a bowling ball (and prove to be more awkward), the Boulder Boots pack away better than a water bottle.

It’s all in the design philosophy. Lems puts the foot above all else — on a pedestal, if you will. The company is known for creating minimalist footwear that supports the natural foot shape with a zero-drop design and roomy toe-boxes. The Boulder Boots encourage the natural walking rhythm of your feet rather than forcing them into an artificially bolstered gait, and happen to look suave too.

Capability, versatility, and convenience are the key qualities of the Lems Boulder Boots. They’re like the little black dress of boots– they’ll work great for any occasion, including light hiking, and you should take them wherever you roam.

The Lems Boulder Boots are best for Urban Hikers, Day Hikers, and Car Campers They perform exceedingly well for anyone accustomed to zero-drop shoes, and would be ideal for international adventures due to their packability.

Gear Review of the Lems Boulder Boot

Origins: Easing You In

I first laced up the Lems Boulder Boots at the tail end of winter when rain and snow were the daily norm here in the Pacific Northwest. It was boot season, the time of year when sidewalks were speckled with puddles and the local trails were squishy with mud and slush.

I wondered how these zero-drop, water-resistant boots would fare. Everywhere was wet, and I was accustomed to wearing waterproof hiking boots when I ventured out on anything more sloshy than a gravel road. Lems does offer waterproof versions of the Boulder Boots, but I tested the standard edition.

The Lems Boulder Boots in Timber. High quality leather and robust nylon make for a durable boot.

And I have to say, I was duly impressed. Through mud and muck, rain and more rain, my feet were kept dry. Not only were they dry, but they also felt comfortable over the various terrain I traversed.

These boots have a zero-drop design, meaning that there is no slope from heel to toe, unlike traditional boots that often feature a moderate rise in the heel to support and soften your step. This flat style can take some getting used to — which is a nice way of saying don’t walk 10 miles during your first day in a zero-drop shoe.

Enjoying the zero-drop life in the Boulder Boots.

For context, I have been running in Altra shoes for the last nine months and have become accustomed to the zero-drop style. The beauty of zero-drop — beyond the relief if it suits your feet and gait — is that each zero-drop shoe is the same. A boot, a trail runner, a basketball shoe, if they are zero-drop it’ll feel similar to your foot.

Revelation: The Moment I Knew

Two specific moments light up in my brain whenever I think about these boots. These thoughts define the affection I have for the Lems Boulder Boots, and they give my heart a fuzzy feeling. Is this love? Boot love, perhaps.

The first time I slid my feet into the Boulder Boots I knew they were much different than any other boot I had ever worn. The nylon uppers were pliable, the interior plaid cotton was soft, and the flat, cushioned insole left my feet feeling as if I had put on my favorite pair of slippers.

A supportive liner plus cozy flannel interior make the Boulder Boots feel like slippers right out of the gate.

It was a fantastic experience. The boots felt like they were molded to my feet right out of the box (not the case for basically any outdoor hiking boot), but the question remained: would they be durable and supportive enough for daily all-purpose duty and a weekend full of hiking?

Short answer: Yeah.

Through town I felt like I was walking around in plush high-top sneakers, but with a stitched-leather exterior that looked mature and professional. Out in the woods, though, is where I became confident that the Boulder Boots could handle it all.

I hiked a few trails in the foothills of the Cascades where everything was covered in moss and dripping with rainwater. Standing atop Royal Terrace Falls, looking down at the muddy and root-filled path I had scaled, is when I first understood that these were serious hiking boots.


Not just for the city, the Boulder Boots can handle wet, dirt trails with the best of ’em.

The rubber outsole held tough as I stepped over large rocks and fallen trees, and the wide toe-box allowed my forefoot to naturally spread out for better grip and comfort.

Digging Deeper

The Lems Boulder Boot has a few unique design features beyond the zero-drop.

The 9 millimeter injection blown rubber outsole performed much better than I had expected it to. It’s an extremely lightweight material that is more flexible than my own aging joints could ever hope to be. Naturally, I assumed there would be a compromise and that the underfoot protection would be lacking, but I was wrong.

Lems Boulder Boots review Tread

A solid rubber sole provided capable for any pavement and most trails. However, the lugs aren’t very deep, and will only provide so much traction on slick rock.

That said, the waffle pattern of the sole doesn’t have much depth to it. While it’s plenty grippy for urban use and light to moderate trails, they will likely slip on slick rocks and other treacherous surfaces one finds when backpacking for long stretches.

Next, let’s talk about the midsole. There isn’t one.

Somehow Lems designed a comfortable, supportive boot without a midsole, which is traditionally what gives the foot the most “comfort.” How? I don’t know.

The 3.5 millimeter removable moisture-wicking insole provides all the cushion you’re going to get, but it is enough, even for long walks, much to my surprise.

That’s because the zero-drop design and wide toe-box allow your feet, tendons, and calf muscles to act as a natural suspension system rather than making the shoe do the work with unnatural supports in the heel and elsewhere. Think about it, do you really need to wear high heels every day? While most boots don’t raise your heel quite as much as high heels, it is a significant amount, and we’ve all grown accustomed to wearing them.

On the outside of the Boulder Boot, the leather trim acts as a durable barrier in all the right places, and strong, yet flexible 1200D nylon gives these boots their unmistakable look and feel.

The entire package weighs in at a featherlight 10 ounces. That’s not per boot, that’s the weight of the entire pair. I cannot stress how light this is.

Lems Boulder Boots review packability

The Boulder Boots are also extremely packable. Each boot can be flattened to an inch-thick slab, and I was able to scrunch one down into a ball the size of my favorite Snoopy coffee mug.

Comfort – 4.5 Stars

The Lems Boulder Boots are wonderful to wear with the caveat that you need to adjust to the zero-drop style if you’re not already accustomed to it. I prefer zero-drop shoes over sloped designs, but I do admit that it took a couple of months for my feet, ankles, and calves to fully adjust.

Even without a midsole, and on serious day hikes, the Boulder Boot proved more than comfortable.

Durability – 4 Stars

The Boulder Boot design and materials are top-notch. I have no doubt about the long-term durability of these boots, but the soles are rather thin. This shouldn’t be an issue for most people, but if you plan on undertaking frequent hardcore hikes I suspect the soles will wear down faster than you would like.

Soles – 5 Stars

Again, it comes down to getting comfortable in zero-drop shoes, but walking in the Lems Boulder Boots is a joy. I could parade around in them all day without issue, and my blister-prone feet have not suffered a single hotspot thanks to the cushioned insole and wide toe-box.

Uppers – 4 Stars

I like the moccasin-style of the stitched leather and nylon uppers of the Boulder Boots. The material has proven to be quite water-resistant (despite not being the “waterproof” version) and breathable to boot. The flexibility of the nylon will take some getting used to — see below for more on that.

Highly flexible with plenty of lace control, these boots are easy to get comfortable in. There is spacious wiggle room for your toes, but your heel, midfoot, and ankle all can be locked in as tight as you need thanks to the robust lacing system and flexible nylon uppers.


I have one issue with the Boulder Boots: those nylon uppers can be irritating from time to time.

I may be biased because of my history with more rigid boots, but the pliability of the nylon upper on the Boulder Boot shows itself on uneven terrain. This isn’t an issue on flat surfaces because the boots maintain their shape, but when your foot and ankle are being forced into extreme angles, such as when you’re hiking on uneven trails, the nylon collapses and, being that it is a thick and durable fabric, it has a sharp edge on those creases that can dig into your skin despite the interior cotton lining.

This crease of fabric tends to poke and scratch at my achilles tendon and under my ankles, which is less than ideal for long, technical treks.

That’s the only reason why I wouldn’t take these boots out on anything longer than a moderate day hike.

Final Word

Lems Boulder Boots are lightweight, durable, and comfortable zero-drop boots that wear well on trail and on pavement. They’re versatile travel shoes that’ll pack down as small as your favorite puffy jacket, and weigh as much, too.

  1. Have two pairs of these- Full Leather and the pair you tested. One thing I learned over the years (former SSgt and Eagle Scout) hiking prodigious miles is the importance of having something else to slip into to give ones get a break. These babies do the job PERFECTLY! They pack down super small and are supremely comfortable to wear while performing “camp tasks” and trips to El Baño. Appreciate your write up!

  2. Oliversays:

    How would they be in a hot humid climate?

    1. The nylon version you see here is the one you’d probably want to get for a hot a humid environment. They’re very breathable and comfortable in humid weather — I live in the PNW where humidity is always high (though the temps aren’t always). I’d suggest staying away from the leather or waterproof versions of the Boulder boot if humidity and heat are your primary concerns. The nylon version has served me well, though.
