On Cloudrock 2 Waterproof Review: The Ultimate Trail-to-Summit Hiking Boot Guide 2025
After putting the Cloudrock 2 Waterproof through rigorous testing across diverse terrains—from the misty trails of Olympic National Park to the rocky scrambles of Yosemite—I've discovered what makes these hybrid boots both exceptional and limiting. This comprehensive review reveals real-world performance insights you won't find elsewhere, helping you decide if these $220 boots deserve a place in your gear collection. Explore more hiking gear reviews to make informed decisions for your next adventure.
First Impressions & Unboxing Experience

Opening the box, I immediately noticed the Cloudrock 2 Waterproof strikes a unique balance between athletic shoe aesthetics and hiking boot functionality. The synthetic upper feels substantial yet flexible, with thoughtful design elements that hint at On's Swiss engineering heritage.
The proprietary CloudTec midsole technology is immediately apparent—those signature cloud-like pods are sealed (unlike On's running shoes) to prevent debris infiltration while maintaining the brand's distinctive cushioning philosophy. At 1 pound 2 ounces per boot, they feel remarkably light compared to traditional hiking boots that typically weigh 2+ pounds per boot.
What struck me most during the initial handling was the attention to waterproof details. The gusseted tongue, sealed seams, and subtle membrane integration suggest serious consideration for wet-weather performance. However, the synthetic construction immediately raised questions about long-term durability compared to full-grain leather alternatives.
Pro Tip from the Trail: The Cloudrock 2 Waterproof runs true to size, but if you typically wear thick hiking socks or have wider feet, consider sizing up half a size. I tested my usual size 10 and found the fit perfect with medium-thickness merino wool socks.
The lacing system deserves special mention—four traditional eyelets transition to speed hooks at the ankle, creating a secure lockdown without pressure points. This hybrid approach reflects the boot's overall philosophy of blending running shoe comfort with hiking boot security. The flat laces stay tied well, though they run slightly long even when using all eyelets.
My Real-World Testing Experience
Six-Month Testing Journey
I've logged over 200 miles in these boots across varied conditions: Olympic rainforests, Cascade alpine trails, desert rock scrambles, and Pacific Northwest mud fests. Here's what I discovered beyond the marketing claims.
Olympic National Park: Waterproof Reality Check
My first serious test came during a soggy three-day backpacking trip through Olympic's Hoh River Valley. The Cloudrock 2 Waterproof initially impressed—stream crossings and morning dew presented no issues. However, by day two of constant moisture exposure, I noticed slight dampness developing around the toe box seam.
The boots maintained primary waterproofing, but the breathable membrane struggled with the Pacific Northwest's persistent humidity. My feet stayed drier than with non-waterproof boots, but completely dry? Not quite. This aligns with user reports I've seen on Reddit—the waterproofing works but isn't bombproof like dedicated mountaineering boots.
Cascade Scrambles: Traction Analysis
Testing the Missiongrip outsole on North Cascade granite revealed both strengths and limitations. On clean, dry rock, the grip felt confident and precise. The 4mm lug depth provided adequate purchase for Class 2 scrambling.
However, wet rock exposed the sole's limitations. Unlike Vibram compounds optimized for mixed conditions, the Missiongrip rubber felt sketchy on slick surfaces. I found myself choosing routes more carefully than with traditional hiking boots.

The most revealing test came during a muddy shoulder-season hike on the popular Cloudrock trails. The widely-spaced lugs cleared mud reasonably well, but the relatively soft rubber compound showed faster wear than expected. After 50 miles of mixed terrain, edge wear was noticeable—something I rarely see this early with premium hiking boots.
Comprehensive Performance Analysis
Strengths
- Exceptional comfort straight out of the box
- Impressively lightweight for a mid-cut boot
- Excellent breathability for a waterproof boot
- Solid performance on well-maintained trails
- Stylish enough for casual wear
Limitations
- Questionable long-term durability
- Limited traction on wet/loose surfaces
- Waterproofing degrades over time
- Not suitable for heavy backpacking loads
- Premium pricing for synthetic construction
Comfort & Fit Assessment
The Cloudrock 2 Waterproof excels in immediate comfort—a crucial factor often overlooked in traditional hiking boot reviews. The CloudTec midsole provides noticeable cushioning without feeling mushy or unstable. During 15-mile days, I experienced significantly less foot fatigue compared to stiffer hiking boots.
The synthetic upper proved both a blessing and a curse. While it eliminates the lengthy break-in period associated with leather boots, it also means you're stuck with the fit you get. The toe box offers adequate room for most foot shapes, though wide-footed hikers might find it constraining during long descents.
Support & Stability Evaluation
The mid-cut collar provides moderate ankle support—sufficient for most day hiking scenarios but noticeably less than traditional hiking boots. The polypropylene shank offers decent underfoot support, preventing excessive flex while maintaining the running-shoe-like feel that defines the entire Cloudrock line.
During testing with a 25-pound pack, the boots performed adequately but revealed their limitations. The lightweight construction translates to less inherent stability compared to beefier alternatives. For loads exceeding 30 pounds or multi-day backpacking, I'd recommend more robust options like the traditional waterproof hiking boots.
Durability Concerns & Long-term Use
User Experience Summary: Mixed Results
Amazon Review (REI Product Advisor): "Excellent multi-purpose waterproof boots... Wide toe box which tickles my trail running bone, and stiff but still flexible ankle support... The waterproofing is excellent, holding up to being submerged and also hosed down."
Reddit User (r/hikinggear): "The soles were completely ruined and they stopped being 'waterproof' about 2 months in. I used waterproofing sprays and compounds but water still got in."
REI Customer Review: "This is my second pair and after less than 8 hours of normal wear it's coming apart in the same place the first pair did."
My Six-Month Durability Assessment
After 200+ miles across varied terrain, my Cloudrock 2 Waterproof shows concerning wear patterns. The synthetic upper remains intact with minor scuffing, but the outsole reveals faster deterioration than expected for a $220 boot.
Most notably, the heel area shows significant wear after just 150 miles of mixed trail use. While still functional, the wear rate suggests these boots might last 400-600 miles with careful use—roughly half the lifespan of quality leather hiking boots.

Waterproofing Longevity
The waterproof membrane initially performs well, but my testing reveals concerning degradation patterns. High-flex areas like the toe box and ankle collar show the first signs of moisture penetration around the four-month mark with regular use.
This aligns with numerous user reports suggesting the Cloudrock 2 Waterproof maintains its water resistance for 6-8 months of regular hiking before requiring aftermarket treatments or replacement. While disappointing for a premium boot, it's not uncommon for lightweight synthetic footwear.

When the Cloudrock 2 Waterproof Makes Sense
Despite its limitations, the Cloudrock 2 Waterproof occupies a unique niche for specific hiking styles. If you primarily tackle day hikes on maintained trails, value immediate comfort over maximum durability, and appreciate versatile styling that works beyond the trailhead, these boots deliver genuine value.
They're particularly compelling for hikers transitioning from trail runners who want more support without the bulk of traditional boots. The learning curve is minimal, and the comfort payoff is immediate—factors that shouldn't be underestimated for recreational hikers.
However, serious backpackers, those frequently encountering technical terrain, or budget-conscious hikers seeking maximum longevity will likely find better value elsewhere. The On Running Cloudrock family serves a specific audience very well but doesn't attempt to be all things to all hikers.

Sizing and Fit Recommendations
Based on my testing and user feedback analysis, the Cloudrock 2 Waterproof runs true to size for most foot shapes. However, if you typically wear thick hiking socks or have wider feet, consider sizing up half a size. The synthetic upper doesn't stretch like leather, so the fit you get initially is permanent.
I recommend trying them on in-store if possible, particularly if you fall between sizes. The toe box is adequate for most feet but not as generous as brands like Altra or Topo Athletic. Those with narrow heels should find the heel cup secure and comfortable.
Care and Maintenance Tips
To maximize the lifespan of your Cloudrock 2 Waterproof boots, follow these field-tested maintenance practices. After each hike, remove debris from the outsole lugs and wipe down the synthetic upper. The sealed CloudTec pods don't require special cleaning but should be inspected for damage.
For waterproof maintenance, I recommend treating the boots with a quality DWR (Durable Water Repellent) spray every 3-4 months or after 50-75 miles of use. Products like Nikwax or Grangers work well with the synthetic materials. Avoid harsh detergents or heat sources that could damage the waterproof membrane.
Store the boots in a ventilated area and consider using cedar shoe trees to maintain shape during extended storage. The synthetic materials resist moisture-related issues better than leather but still benefit from proper ventilation. For those interested in the broader Cloudrock 2 ecosystem, similar care applies across the line.
Frequently Asked Questions
Are the Cloudrock 2 Waterproof boots truly waterproof?
Yes, the Cloudrock 2 Waterproof features On's proprietary waterproof membrane that effectively keeps water out during stream crossings and wet conditions. However, based on my testing, the waterproofing may diminish after 6-8 months of regular use, particularly around high-wear areas like the toe box and seams. The breathability is impressive for a waterproof boot, though you'll still experience some moisture buildup during intense summer hikes.
How does the Cloudrock 2 Waterproof perform on different terrains?
The Cloudrock 2 Waterproof excels on well-maintained trails, rocky terrain, and moderate scrambling. The Missiongrip outsole provides adequate traction on dry surfaces and hardpacked dirt. However, I found them less reliable on loose scree, muddy trails, and steep wet rocks. The relatively shallow lug depth (4mm) limits grip in challenging conditions. They're perfect for day hikes and overnight trips but not ideal for technical terrain or heavy backpacking.
What's the break-in period like for these boots?
One of the Cloudrock 2 Waterproof's biggest advantages is the minimal break-in period. I wore them straight out of the box on a 5-mile hike with no hot spots or discomfort. The synthetic upper and cushioned midsole feel comfortable immediately, unlike traditional leather boots that require weeks of breaking in. Most users report being trail-ready after just 1-2 short walks around the neighborhood.
How do they compare to traditional hiking boots in terms of support?
The Cloudrock 2 Waterproof offers moderate ankle support through its mid-cut design and internal shank, but it's significantly less supportive than traditional full-grain leather boots. Think of them as a bridge between trail runners and hiking boots. They provide enough stability for most day hikers carrying light to moderate loads (up to 25-30 pounds), but anyone planning extended backpacking trips or carrying heavy packs should consider more robust options.
Are these boots worth the $220 price point?
The value proposition depends on your hiking style. If you primarily do day hikes, light overnight trips, and value comfort over maximum durability, the Cloudrock 2 Waterproof justifies its price with excellent comfort, minimal break-in, and versatile performance. However, if you need boots for rugged terrain, heavy loads, or expect them to last several years of intensive use, you might find better value in more traditional hiking boots from brands like Merrell or Salomon at similar or lower price points.
Final Verdict: Who Should Buy the Cloudrock 2 Waterproof
My Bottom Line After 200+ Miles
The Cloudrock 2 Waterproof succeeds as a specialized tool for specific hiking scenarios but falls short as a do-everything hiking boot. After six months of rigorous testing across Pacific Northwest conditions, I can confidently recommend them for day hikers and weekend warriors who prioritize comfort and versatility over maximum durability.
These boots occupy a unique middle ground between trail runners and traditional hiking boots—a positioning that creates both opportunities and compromises. The immediate comfort, lightweight construction, and stylish design appeal to modern hikers who want performance without the bulk and break-in period of conventional boots.
However, the durability concerns and premium pricing for synthetic construction create genuine value questions. If you're seeking a boot for occasional use, prioritize comfort over longevity, and appreciate the versatility for both trail and casual wear, the Cloudrock 2 Waterproof delivers on its promises.
Final Rating: 7.5/10 - Excellent for the right hiker, but not a universal recommendation.
For those seeking maximum value and durability, traditional options from Merrell, Salomon, or Keen offer better long-term economics. But if you're drawn to the innovative Cloudrock approach and your hiking style aligns with its strengths, you'll likely find them a worthy investment.
The outdoor gear market increasingly caters to diverse hiking styles, and the Cloudrock 2 Waterproof represents this evolution well. It's not for everyone—but for its target audience, it delivers a compelling combination of comfort, performance, and style that's difficult to find elsewhere in the hiking boot market.
