Our Take:
4.1/5
We’ve been lukewarm about On’s hiking footwear in the past, but the latest Cloudrock Mid ($220) feels like a meaningful step forward. The boot combines trail runner-inspired agility with enough structure for on-trail backpacking, and its durability impresses for the sub-2-pound weight. It’s not the grippiest boot out there, nor does it shine in any one area, but the design is cohesive and well-executed. For hikers and backpackers looking for a modern-feeling boot that’s light, supportive enough, and built to last, the Cloudrock is worth a look.

Pros

Significantly more capable than its predecessors.
Lightweight and nimble feel.
Like most On products, the styling and build quality are top notch.

Cons

Despite improvements, its outsole design is still only average and lacks bite in tricky and technical terrain.
Feels shapeless and pretty flat underfoot.
We’d prefer more toe and foot protection.

We tested the previous Cloudrock 2 and found the latest On Cloudrock Mid maintains a similar feel: a responsive, medium-cushioned boot that blends trail runner traits with more traditional hiking support. It’s not plush underfoot like many Hokas, but the ample midsole foam and signature Cloudtec cutouts do a great job absorbing impact. After full days on the trail, the Cloudrock impressed with strong shock absorption and minimal foot fatigue—especially notable given I found that On’s hiking footwear historically felt overly firm and board-like.


That said, the underfoot feel is still fairly flat and lacking in shape, though the lacing system does a good job locking down the foot. Break-in was minimal: the tightly woven synthetic upper feels a bit stiff at first but flexes well and didn’t cause any rubbing or hot spots. The boot rides just above the ankle with moderate padding that cushions well even when laced snugly, and the tongue is equally well-padded. Rounding out the comfort story is the boot’s low weight and nimble, athletic feel—it wears more like a rugged trail shoe than a clunky hiking boot.

The On Cloudrock has the look and feel of a modern lightweight hiker, and its level of support matches that profile. A key structural element is the X-shaped stiffener above the outsole, which adds some rigidity compared to trail runner–based mids like Altra’s Lone Peak (for more on that boot, see our review of the Lone Peak Hiker 3). The collar rises just above the ankle, and the lacing system—anchored by wide-set eyelets—does a good job securing the foot by snugging evenly both below and around the ankle.


Under the weight of an overnight pack, I found the Cloudrock offers a reassuring level of ankle support, especially when compared back-to-back with my low-top Salomon X Ultra 5s. That said, the X Ultra’s base is stiffer, and the On still has noticeable give—it resists collapse and rolling to a point, but it’s far from a true mountain boot. The heel counter is lightly reinforced, and the overall platform flexes under load more than heavier-duty options. For day hikers seeking more structure than a standard low-top, or backpackers sticking to well-maintained trails with moderate packs, the Cloudrock is up to the task. But if you’re looking for true backpacking-level support, burlier models like the Hoka Kaha 3, Salomon Quest 4, or Lowa Renegade will be the better bet.

The prior-generation Cloudrock 2 struggled in technical terrain, and On has made clear improvements with this latest model. The updated outsole uses a revised rubber compound and reworked lug shape, resulting in a noticeable bump in grip—from underwhelming to roughly average. The tread features small, rectangular lugs that offer decent traction on dry rock and well-maintained trails, but their relatively short height limits their effectiveness in looser or more variable terrain.


Compared to more aggressive hiking boots like the Adidas Terrex Free Hiker 2.0 or Salomon’s X Ultra 5, the Cloudrock’s outsole lacks bite, especially in mud or on steep descents where deeper lugs dig in more securely (for more, read our X Ultra 5 Mid review). Overall, this is a boot best suited for on-trail use in fair conditions. It’s no longer a liability like its predecessor, but still not the best choice for technical, rock-hopping, or mixed-surface environments.

For a sub-2-pound hiking boot, the On Cloudrock offers solid durability. The tightly woven polyester upper is noticeably more resilient than more open-weave synthetics, resisting damage from rocks, roots, and trail debris. A full interior liner adds tear resistance beneath the waterproof membrane, while TPU overlays along the sides of the foot provide extra protection in high-wear zones. Build quality is high across the board, with clean stitching and premium materials used at the collar and ankle.


The midsole has some semi-exposed foam, but the rubber sections have only picked up minor scuffs so far—no chipping or chunks falling off like we’ve seen on some Hokas. The outsole is wearing evenly, and while the upper can’t match the long-term toughness of full leather, that’s a known tradeoff for the weight savings. Overall, if you stay within its intended use—on-trail hiking and moderate backpacking—the Cloudrock should hold up well over time.

The Cloudrock’s trail runner heritage shows in its modest protection levels. Up front, the toe cap covers most of the forefoot—just shy of the pinky toe—but it’s lightly reinforced and doesn’t offer the rigidity of a full rubber bumper, allowing some impact to come through on direct rock hits. The sides are similarly light-duty, with TPU overlays and a multi-layer upper offering basic cushioning but limited shielding. Around the heel and ankle, padding does a nice job of softening accidental bumps against rock. Underfoot is where the On Cloudrock Mid performs best: the medium-density foam midsole and integrated stiffening board help buffer sharp rocks and debris, providing a solid foundation for moderate trail use.

Longevity

Choosing durable outdoor gear is perhaps the most effective way to reduce environmental impact—the longer it lasts, the less it needs to be produced. Our proprietary longevity rating evaluates overall build quality based on factors such as materials, fabric denier, component durability (including zippers and toggles), real-world performance as reported by our field testers, and our experiences with the brand.

The Cloudrock Mid feels as light and nimble as it looks, and my scale confirms it: a men’s size 9 pair came in at 1 pound 15.4 ounces, nearly matching the listed weight of 1 pound 15.1 ounces. That undercuts slightly burlier competitors like the Hoka Anacapa 2 and Adidas Terrex Free Hiker 2.0 (both around 2 pounds 4 ounces), aligns closely with the Salomon X Ultra 5 Mid GTX (1 lb. 15 oz.), and is just a touch heavier than the minimalist Merrell Moab 2 Speed (1 lb. 12.2 oz.). For hikers wanting a lightweight feel without giving up the security and durability of a boot, the Cloudrock strikes a well-balanced middle ground.

Waterproof Liner
The Cloudrock Mid features a waterproof liner, sturdy mesh upper, and DWR finish that together offer reliable moisture protection. In testing, water beaded and rolled off the surface effectively, and even after standing in a creek for a few minutes, the upper didn’t absorb moisture—something full-leather boots often struggle with. Keep in mind that the tongue only attaches midway up the ankle, which sets the limit for how deep you can submerge the boot before water seeps in.


Like most waterproof hiking boots, breathability is limited. I run warm, and in temps between 50 and 80 degrees with a loaded pack, my feet were consistently hot and sweaty—something likely exacerbated by the dark color of my test pair. And while the thin synthetic upper is quick to dry, it doesn’t offer much ventilation.

Lacing System
At first glance, the Cloudrock’s lacing system appears conventional: a series of fabric eyelets down low with two metal hooks at the top. But On widened the spacing across the forefoot, which helped me achieve a snug and comfortable fit over my slightly narrow feet. The laces also wrap partially around the ankle, adding to the boot’s secure feel. I had no trouble dialing in the tension, and the laces held firmly throughout full days on the trail without requiring adjustment.

Lacing up the On Cloudrock Mid hiking boot

I’m consistently a men’s size 9 with a slightly narrow heel and prefer an average-width toe box, and the Cloudrock Mid fit well right out of the box. For a hiking boot—where a little extra space is helpful for thicker socks and avoiding toe bang on descents—the sizing felt spot-on. I wore the boots with Darn Tough’s Micro Crew Cushioned Socks and had no issues with comfort or length.


The customizable lacing system also made it easy to get a secure fit. One caveat: the included insole is quite flat and lacks arch support. Hikers with more pronounced arches may want to consider swapping in a more supportive aftermarket option.

Hoka Anacapa 2 Mid GTX ($195): Comfort First
The Anacapa 2 Mid is one of the most cushioned boots on the market, with a plush EVA midsole that absorbs impact better than the On Cloudrock’s firmer, flatter ride. The Hoka also uses premium materials like a Vibram Megagrip outsole for excellent traction, outclassing the Cloudrock in grip and confidence on variable terrain. That said, the Hoka is softer and less precise, with a floppier upper and rocker shape that can feel bulky or clunky depending on the user. Durability is also more of a concern, with the exposed foam and less protective build picking up wear quickly. Both boots land in the lightweight category and work well for on-trail adventures, but the Anacapa is for hikers who prioritize max cushion and comfort, while the Cloudrock is more streamlined and performance-oriented. For more, read our Hoka Anacapa 2 Mid GTX review.

Salomon X Ultra 5 Mid GTX ($185): More grip and precision, less visual flash
The Salomon X Ultra 5 Mid is a top-performing trail-ready boot that shares a lot with the On Cloudrock Mid: both weigh under 2 pounds, offer good out-of-the-box comfort, and provide enough support for moderate backpacking loads. But the Salomon is the more capable performer on rough terrain. Its All Terrain Contagrip outsole delivers noticeably better grip on rock and steeps than the Cloudrock’s shallow lugs, and it includes more extensive foot protection and a reinforced upper that better resists wear. The Cloudrock fights back with more modern looks and a slightly roomier, less snug fit through the forefoot. But for those who want a trail boot that can do a bit of everything and has the traction and durability to back it up, the X Ultra 5 is the more confidence-inspiring choice. For more, check out our review of the Salomon X Ultra 5 Mid GTX.

4.1/5

This unique hiking boot is a comfortable and stylish option for non-technical trails, with more stability than you’d expect. However, they aren’t particularly protective, and traction falls short of the competition.

For those who prioritize comfort, the Anacapa is a plush, breathable hiking boot from Hoka with a lot to like. Throw in a lower price tag than the Kaha line and a lighter weight, and we’re officially intrigued.

One of the best all-arounders we tested, the Salomon X Ultra 5 Mid GTX delivers impressive support, protection, and durability for its low weight. However, it's not stiff or protective as a true mountain boot, and the thick tongue can make ankle tension harder to dial in.

Is the On Cloudrock Mid for You?

The On Cloudrock Mid is a good match for hikers who want a modern design. It’s not as burly as traditional backpacking boots, but it's far lighter, more cushioned, and hits a sweet spot for fast-moving day hikes and light overnight trips on established trails. If you prioritize weight savings, sleek styling, and a responsive feel underfoot—and are willing to trade off some support and traction in more technical terrain—the Cloudrock Mid is a compelling choice.
