I recently tested the Brooks Cascadia 18 on a multi-day trip near the Phou Pha Mone region in Laos, a spot known for its scenic mountain trails, varied terrain, and steep inclines that can push even top-tier trail running gear to the limit.
Over about 60 miles of dirt paths, slick stone steps, and humid lowlands, I checked out how well this trail running shoe handles everything from casual hiking to serious mileage.
This review is part of my ongoing mission to find standout trail running shoes for both seasoned trail runners and those new to the sport.
Early on, I noticed solid stability, a solid upper construction, and a generally stable platform, though the shoe does feel a bit heavy, and the midsole loses some bounce after long runs.
Let’s jump into this Brooks Cascadia 18 review and see how it performed across various surfaces.
Our Verdict 4.6/5
The Brooks Cascadia 18 is a durable trail running shoe designed to handle technical terrain with confidence. The Trail Adapt design and rock plate provided reliable control on uneven trails and the TrailTrack Green outsole offered dependable grip on wet and dry surfaces.
Over long miles, the midsole softened slightly, reducing some of its initial bounce, and its heavier build is noticeable on speed-focused runs.
However, for runners and hikers prioritizing durability and all-terrain versatility, the Cascadia 18 is a solid, well-cushioned choice that holds up when the trails get challenging.
To deliver a well-rounded review of the Brooks Cascadia 18, we carried out in-depth testing across a variety of terrains, including smooth trails, rocky routes, muddy stretches, and loose gravel. We assessed its water resistance in wet environments and its durability under high-heat conditions. Both our internal team and external trail-running experts evaluated the shoe’s break-in period and long-term comfort. We paid close attention to critical features such as fit, cushioning, traction, and breathability. Additionally, we gathered user insights and examined the manufacturer’s warranty to provide a comprehensive perspective on the Cascadia 18.

Detailed Performance Breakdown
1) Durability
Ultrarunning legend Scott Jurek ran the Appalachian Trail in a record-breaking 46 days while wearing Cascadia shoes, so I had high expectations for their durability.
The Brooks Cascadia 18 shoe features a mesh upper design reinforced in high-wear areas (like the toe cap and lace zones). After muddy trails, sharp debris, and root-heavy sections, I only saw small marks—pretty good for a trail running shoe made for rugged terrain.
Meanwhile, the TrailTrack Green outsole held up well, with minimal lug damage. The DNA Loft v2 midsole, known for its soft cushioning, did show mild compression while testing for this Brooks Cascadia 18 review, aligning with other premium Brooks shoes I’ve tried like the Levitate 4 and Hyperion Elite.
Compared to a traditional hiking shoe, it’s more flexible but still stands up decently over time.
2) Traction
Traction is a make-or-break attribute for a trail running shoe, especially on technical terrain and steep inclines.
The Brooks Cascadia 18 packs the brand’s trail adapt system, merging the 4.5mm lugs with midsole geometry that yields great stability and improved ground feel.
In Laos, where wet leaves, loose gravel, and clay-based soils are commonplace, the outsole seldom slipped.
Mud occasionally stuck between lugs in extremely sticky spots and soft ground, but a quick scuff on a rock cleared it. On damp logs or slippery rocks, the Cascadia 18 outperformed plenty of other models in the Brooks lineup, supporting a secure stance.
This shoe might not boast hyper-aggressive grips like specialized winter boots, but for multi-season trail running, it has more than enough bite.
3) Weight
Weighing roughly 10.9 oz per shoe, the Cascadia 18 sits firmly on the heavier side of modern trail running footwear.
Initially, I assumed the extra weight might hamper quick tempo sessions, but it delivered a reliable platform that prevented ankle rolls on uneven trail surfaces.
For heel strikers in particular, the added heft can actually provide extra support during descents.
During tighter switchbacks, the Cascadia 18 still felt nimble enough, balancing the cushioned feel with moderate agility. If you’re used to a super-minimal road running shoe, there’s a big difference, particularly for runners seeking to maintain a zippy stride.
Yet for cross-country slogs or multi-hour hikes, the secure ride overshadowed any slight dip in raw speed, boosting my confidence on precarious ground.
4) Comfort
Thanks to the DNA Loft v2 foam, the Brooks Cascadia 18 delivers a solid mix of balanced cushioning and quick response on long runs. My foot felt well-supported without sinking too much.
The wide toe box lets your big toe and other toes spread out naturally, a real plus on long descents when things can get cramped.
I also liked the horizontal elastic strip located partway down the tongue, which lets you tuck your laces away. This not only prevents them from coming undone in the undergrowth but also helps keep them cleaner.
The sturdy heel counter gives you a snug fit around the heel, though heel strikers might need to adjust their laces a bit for extra lock. This setup cuts down on friction, so I didn’t get many blisters, even on humid days.
If you’re used to narrower shoes, the forefoot might feel a bit roomy, but it never feels sloppy—just comfortable, especially after breaking it in for 30–40 miles.
5) Breathability
As I have already mentioned, the testing for this Brooks Cascadia 18 review took place in warm, often wet conditions. I found the mesh upper lets air flow pretty well, keeping my feet cool except during the hottest afternoons.
Light crosswinds helped the shoes dry quickly after shallow creek crossings. Overall, moisture build-up was minimal, so I didn’t deal with any hotspots or that soggy-sock feeling.
If you opt for the GTX model, you’ll get top-notch waterproof protection—but you’ll lose some of that open, breezy feel. Given Laos’s tropical climate, I appreciated the standard model’s breathability, especially on sweaty climbs.
For those needing something winter-friendly or fully waterproof, the sealed version might be the way to go, even though it runs a bit warmer and slightly heavier.
6) Waterproofing
Brooks offers both standard and GTX versions of the Cascadia 18. In my quick tests, the GTX style kept out moderate rain and wet grass pretty well, so your foot stays drier.
The downside is that your feet don’t cool as much because the moisture can’t escape as easily.
On the flip side, the standard Cascadia 18 uses a quick-drying upper, so a splash or a passing shower won’t leave you soaking for long.
If you’re often hiking in rainy or chilly conditions, the sealed version might feel safer.
In my runs during tropical storms, I really appreciated how the standard model let water in and out quickly. Ultimately, the best choice comes down to your local weather.
7) Support
The Brooks Cascadia 18 trail running shoe stands out for its stability on technical terrain, thanks to its trail adapt design. It’s a more stable platform than some older Cascadia models I’ve tried, largely due to the well-shaped foam that spreads your weight evenly.
The built-in rock plate does a solid job protecting your foot from sharp stones or roots.
Plus, the updated heel counter—and the option for a gaiter attachment—adds extra debris protection. Whether you’re running on rough ridgelines or training in muddy local parks, your foot stays secure without rolling around.
Still, the shoes are soft enough to be comfortable.
Another neat detail is the laces, which include a bit of bungee give for extra comfort. If you need a bit of arch support or extra help around your ankles, these features deliver a secure feel that competes with the heavier, more protective options found in traditional hiking shoes.
8) Fit and Sizing
The Brooks Cascadia 18 runs true to size for most runners, including me. The toe box is roomy, giving your big toe plenty of space so your feet don’t feel cramped, especially useful on long runs when your foot might swell. Plus, the improved heel lock keeps your heel snug with minimal slipping.
Compared to some other models, like the narrower Brooks Glycerin in the road category, the Cascadia 18 trail shoe offers extra forefoot volume, which is great if you like extra breathing room or wear thicker socks on cold runs.
If you’re between sizes, consider going up half a size for a bit more comfort, but standard sizing usually works just fine with minimal break-in.
Brooks Cascadia 18 Evolution
Compared to last year’s model, the new Cascadia 18 feels a bit lighter and has more cushioning thanks to the updated DNA Loft v2 foam.
The upper now includes more recycled materials, making it tougher overall, while a reinforced heel gives a better lockdown. Plus, the refreshed outsole pattern offers enhanced traction on technical trail terrain.
It’s not a complete overhaul, but these tweaks address minor issues from the previous version—like a narrower toe box and quicker wear around the overlays.
Overall, the new trail shoe shines in comfort and usability over long distances, offering a higher cushioning level and durability than the last model.
Brooks Cascadia 18 Competitors
The Brooks Cascadia 18 has earned its spot as a go-to for trail fans who need an all-around trail running shoe. Here’s how it stacks up against some popular rivals:
La Sportiva Bushido III
La Sportiva’s Bushido III is a favorite among serious trail runners tackling steep, rocky climbs.
This shoe features a firm platform and a precise fit, but that tightness can feel a bit harsh on longer runs.
In contrast, the Cascadia 18—a key member of the Cascadia line—delivers a secure ride with balanced cushioning that keeps your foot from feeling hammered during extended sessions.
While the Bushido III is more “race-ready” for short, intense efforts, the Brooks Cascadia 18 gives you almost perfect balance if you mix in some hiking or slower-paced runs.
Hoka Torrent 3
Hoka’s Torrent 3 is known as a lightweight, mid-cushion shoe that blends aspects of a road running shoe with moderate off-road capability.
It’s quick on groomed trails and easy runs, but if you’re venturing into truly technical terrain or logging long distances, you might need something a bit sturdier.
The Brooks Cascadia 18 shoe steps up with a built-in rock plate for extra protection, making it a more dependable choice on rough ground, although it does weigh a bit more.
If you prefer more speed on smooth trails, the Torrent 3 might be appealing; for more technical routes, the Cascadia 18 holds its ground.
Brooks Divide 5
Within the Brooks family, the Divide 5 serves as an entry-level, more lightweight trail shoe for casual outings or shorter runs.
It’s more budget-friendly, but it can’t match the extra support, impressive traction, or overall secure platform of the Cascadia 18, especially on technical trails or mountain trails.
The Cascadia 18 shoe comes with better protective features like a reinforced toe cap and rock plate, plus a more cushioned midsole for those long distances.
If you’re just starting out on casual trails or looking for a better ground feel, a pair of Divide 5 can be a great option. But when the mileage or the terrain gets trickier, the Brooks Cascadia 18 clearly steps up as the superior option.
Brooks Cascadia 18 Strengths
From firsthand testing, the Brooks Cascadia 18 really shines if you need excellent stability and steady traction on various terrains, including those more technical.
For anyone logging long miles, it offers a stable ride and protects your foot with its integrated plate, especially handy on mountain trails or backcountry treks where the ground can shift from muddy to rocky in a flash.
Another big plus is the roomy toe box; it gives your big toe plenty of space so you never feel pinched, and the supportive heel counter adds extra confidence to every step.
All in all, if you’re looking for one versatile trail running shoe that can handle everything from weekend loops to serious backcountry adventures, the Cascadia 18 stands out as a dependable choice in the Brooks stable.
Brooks Cascadia 18 Weaknesses
Despite its strengths, the Cascadia 18 isn’t without its drawbacks. For speed-focused runners or those who lean toward a minimalist style, it can feel a bit heavy compared to a pure road running shoe or super-light racing flats.
During extended runs, I noticed that the midsole can flatten out a bit, which means you might lose some of that initial cushioned feel after a lot of pounding.
Also, the Gore-Tex model tends to run hot in warm climates, making it less breathable if you’re tackling tropical or desert conditions. That sealed design works better in rainy or wintry weather. And while the toe cap and overlays do a great job protecting your foot, they can feel a bit stiff if you’re used to a more sock-like upper.
