- Waterproof: Gore-Tex
- Outsole: Contagrip MA
- Best For: Day hiking, fast-packing
When I first unboxed the Salomon X Ultra 4 GTX, I was immediately struck by how lightweight they felt compared to my previous hiking boots. At just 14 ounces, these shoes challenge the traditional notion that you need heavy, bulky boots for serious hiking. The synthetic upper with strategic leather reinforcements gives them a modern, technical appearance that screams performance.
The Advanced Chassis (ADV-C) system is immediately noticeable – you can feel the structured support underfoot even when just trying them on. The Quicklace system, while polarizing among users, allows for rapid on-and-off convenience that I've grown to appreciate during multi-day trips. However, my first impression was that the ankle collar felt higher than expected for a low-cut shoe, which would later prove both beneficial and problematic during extended wear.
What sets the X Ultra 4 apart from competitors like the previous X Ultra 3 model is the refined balance between trail runner agility and hiking boot protection. The toe box feels roomier than its predecessor, and the overall construction quality appears robust, though as I'll discuss later, this initial impression doesn't tell the whole durability story.
Performance Analysis: Traction & Stability
The Contagrip MA outsole is where the X Ultra 4 truly shines. During my testing on the challenging granite slabs of Yosemite and the loose scree of Colorado's fourteeners, these shoes consistently outperformed my expectations. The chevron-patterned lugs provide exceptional grip on both wet and dry surfaces, with the rubber compound striking an ideal balance between stickiness and durability.
What impressed me most was the shoe's performance on technical descents. The Advanced Chassis system provides remarkable lateral stability without sacrificing the flexibility needed for varied terrain. I felt confident navigating loose rock sections that would typically require more cautious footwork in standard trail runners.
Traction Performance by Terrain
Rocky/Technical: 9/10
Excellent grip on granite and limestone. Confidence-inspiring on exposed sections.
Mud/Loose Dirt: 7/10
Good performance, though lugs can pack with clay. Self-cleaning is adequate.
Wet Surfaces: 8/10
Surprisingly capable on wet rock and trail surfaces. Gore-Tex adds security.
The stability system truly differentiates these from basic trail runners. During river crossings and off-trail scrambling, I noticed significantly less ankle fatigue compared to my previous Salomon models. However, this enhanced support comes with a slight weight penalty that purists might notice during ultralight adventures.
Pro Tip: The Contagrip compound performs best when warmed up. Allow 10-15 minutes of walking for optimal traction on technical terrain.
Comfort & Fit: Real-World Testing
Comfort is where the X Ultra 4 presents a complex story. During my first 20-mile day on the John Muir Trail, I experienced what many users report: initial pressure points around the ankle collar that required careful lace adjustment. The synthetic materials don't offer the same give as leather, meaning proper fit from day one is crucial.
The Ortholite insole provides adequate cushioning for day hikes, though I found myself wanting more underfoot padding during longer efforts with heavy packs. What impressed me was the toe box space – significantly improved from the X Ultra 3 generation. My feet never felt cramped during descents, a common issue with previous models.
My Experience: Breaking Them In
Unlike traditional leather boots, the X Ultra 4 requires a different break-in approach. I spent the first week wearing them around town for 2-3 hours daily, focusing on adjusting the Quicklace system to eliminate pressure points. The key breakthrough came when I loosened the laces through the midfoot while maintaining snugness around the heel – this configuration eliminated the ankle rubbing that plagued my first few hikes.
Comfort Challenges
- Higher ankle collar can cause rubbing
- Quicklace system loosens over time
- Synthetic materials less forgiving
- Limited cushioning for heavy loads
Comfort Wins
- Excellent toe box roominess
- No break-in period once adjusted
- Breathable for synthetic construction
- Secure heel lock when properly laced
For sizing, I found these run true to size, though users with wide feet should consider the wide version. The women's model addresses some of the fit issues through gender-specific modifications, according to several female hiking partners who tested both versions.
Durability & Build Quality Concerns
This is where my review takes a more critical turn, and frankly, where Salomon has disappointed many long-term users. After 200+ miles of testing, I've observed concerning durability issues that align with widespread user complaints since the brand's acquisition by Chinese parent company Anta Sports in 2019.
The most problematic area is the synthetic upper construction around the toe box. Unlike the robust X Ultra 3 model, the X Ultra 4 uses more welded seams and thinner materials to reduce weight. While this achieves the lightweight goal, it compromises long-term durability significantly.
User Review Summary: The Reality Check
Amazon Customer "Mountain Goat" (663 miles): "I am getting another pair of these shoes since I just blew out my first pair yesterday after two seasons. I have gotten less than a season out of other shoes." - However, this positive review contrasts sharply with more recent experiences.
Reddit User Experience: "The soles wore off VERY quickly and became dangerous to hike in... Initially they were great, very comfortable and grippy on the trail." - This reflects the common pattern of good initial performance followed by rapid degradation.
REI Customer Feedback: Multiple 1-star reviews cite premature failure within 4-6 months of moderate use, with particular issues around heel padding separation and outsole delamination.
Durability Red Flags
- Sole wear after 100-200 miles
- Heel padding degradation
- Upper material tearing
- Inconsistent quality control
What Still Works
- Gore-Tex membrane integrity
- Lacing system hardware
- Initial traction performance
- Structural chassis durability
My personal pair shows moderate outsole wear after 200 miles, with the heel area displaying the soft rubber wearing faster than expected. The upper remains intact, but I can see stress points developing around high-flex areas. For comparison, my previous Salomon models from 2018 lasted over 500 miles with similar use patterns.
Reality Check: If durability is your primary concern, consider the older X Ultra 3 model if still available, or look at alternatives like Lowa or Merrell for better longevity.
Waterproofing & Weather Protection
The Gore-Tex membrane remains one of the X Ultra 4's strongest features. Throughout my testing in Pacific Northwest conditions, including stream crossings and unexpected downpours, these shoes consistently kept my feet dry. The gusseted tongue design effectively prevents water entry from the top, while the raised eyelets add an extra layer of protection.
What surprised me was the breathability performance. Despite the waterproof membrane, I rarely experienced the swamp-foot sensation common with Gore-Tex footwear. The synthetic upper materials and strategic ventilation seem well-designed for moisture management during high-output activities.
Seasonal Performance Testing
Spring/Fall Conditions
Excellent performance in wet conditions. No water entry during 6+ hour rainy hikes. Some condensation with heavy exertion.
Summer Heat
Surprisingly breathable for Gore-Tex. Better than expected in 80°F+ temperatures, though not as airy as non-waterproof options.
Stream Crossings
Reliable waterproofing up to mid-ankle depth. Quick drainage when water overtops. No delamination observed.
The low-cut design does limit deep water capabilities compared to mid or high-top alternatives. For serious creek walking or snow conditions, you might want to consider the X Ultra Trek GTX or mid-height variants.
One notable advantage over competitors is the integration between the Gore-Tex membrane and the synthetic upper. Unlike some brands where the waterproof layer feels like an afterthought, Salomon has engineered the entire upper as a waterproof system. This approach contributes to the overall durability of the waterproofing, even as other construction elements may fail prematurely.
Value for Money & Alternatives
At $140-180 retail, the X Ultra 4 GTX sits in a competitive price bracket where every dollar matters. The value proposition depends heavily on your priorities: if you need lightweight performance for day hiking and can accept reduced longevity, these shoes deliver. However, if durability is paramount, your money might be better spent elsewhere.
Best Value Scenarios
- Weekend day hikers (under 200 miles/year)
- Lightweight priority over durability
- Need Gore-Tex at this price point
- Occasional technical terrain
Poor Value Scenarios
- High-mileage hikers (500+ miles/year)
- Backpackers carrying heavy loads
- Budget-conscious buyers seeking longevity
- Commercial or guide use
Better Alternatives to Consider
For Better Durability:
Lowa Renegade GTX: Heavier but built to last 1000+ miles. Better value for high-mileage users despite higher upfront cost.
Merrell Moab 3 GTX: Proven durability, wider fit options, and $50-70 less expensive. Trade-off in technical performance.
Previous X Ultra 3: If you can find them, the older model offers better construction quality with similar performance characteristics.
For Similar Performance:
Hoka Anacapa 2 Mid GTX: Excellent comfort, similar weight, potentially better durability. Higher price point but worth considering.
La Sportiva TX Hike GTX: Superior build quality, technical performance, though less comfortable for casual hiking.
The honest assessment is that while the X Ultra 4 performs well initially, the durability concerns significantly impact its value proposition. For casual hikers who prioritize performance over longevity, they remain a solid choice. For serious hikers putting on significant mileage, investing in more robust alternatives will likely provide better long-term value.
Frequently Asked Questions
Are the Salomon X Ultra 4 GTX worth buying in 2025?
The X Ultra 4 GTX remains worth buying for specific use cases: casual day hikers prioritizing lightweight performance, those needing Gore-Tex waterproofing at this price point, and hikers covering under 200 miles annually. However, high-mileage hikers should consider alternatives due to durability concerns that have emerged since the brand's ownership change. The initial performance is excellent, but longevity has become questionable compared to previous generations.
How do the X Ultra 4 compare to the previous X Ultra 3 model?
The X Ultra 4 offers improved toe box roominess, updated Advanced Chassis technology, and better initial comfort. However, the X Ultra 3 featured superior build quality with more durable materials and construction methods. The newer model uses more synthetic materials and welded seams to reduce weight, but this compromises longevity. If you can find X Ultra 3 models in stock, they may offer better long-term value despite being technically outdated. The performance difference is minimal, but durability favors the older model significantly.
What are the main durability issues with the X Ultra 4?
The primary durability concerns include rapid outsole wear (often within 100-200 miles), heel padding degradation causing discomfort, upper material tearing around high-stress areas, and inconsistent quality control between manufacturing batches. The Quicklace system can also loosen prematurely. These issues represent a significant departure from Salomon's historical build quality, largely attributed to manufacturing changes following the brand's acquisition by Anta Sports. Many users report shoes failing within 4-6 months of moderate use, contrasting sharply with previous models that regularly lasted 500+ miles.
Do the X Ultra 4 GTX run true to size?
Yes, the X Ultra 4 GTX generally runs true to size, though the fit characteristics differ from previous models. The toe box is roomier than the X Ultra 3, which most users appreciate. However, the ankle collar is higher and less padded, which can cause rubbing for some users. People with wide feet should consider the wide version, as the synthetic materials offer less stretch than leather alternatives. I recommend trying them on with hiking socks, as the fit can feel different with various sock thicknesses. The Quicklace system allows for fine-tuning, but proper initial sizing remains crucial for comfort.
How waterproof are the X Ultra 4 GTX in real-world conditions?
The Gore-Tex membrane in the X Ultra 4 GTX performs exceptionally well, maintaining waterproof integrity even when other construction elements begin to fail. In my testing, they remained completely waterproof through stream crossings, heavy rain, and wet terrain up to mid-ankle depth. The gusseted tongue and raised eyelets effectively prevent water entry from above. Breathability is surprisingly good for a Gore-Tex shoe, though some condensation occurs during high-exertion activities in warm conditions. The waterproofing system appears to be one of the few aspects where Salomon has maintained their quality standards, making these suitable for wet-weather hiking despite other durability concerns.

The Salomon X Ultra 4 GTX represents a frustrating paradox in modern outdoor gear: exceptional initial performance undermined by questionable long-term reliability. During my 200+ mile testing period, I consistently appreciated their lightweight agility, technical traction, and waterproof protection. These shoes excel in their intended role as fast-and-light day hiking footwear.
However, the durability concerns are real and significant. The quality control issues that have emerged since Salomon's ownership change represent a betrayal of the brand's reputation for reliability. For casual hikers covering limited annual mileage, these concerns may be manageable. For serious hikers depending on their gear, they represent a genuine risk.
My recommendation is nuanced: if you prioritize performance over longevity and hike fewer than 200 miles annually, the X Ultra 4 GTX can serve you well. Take advantage of REI's generous return policy or similar retailer guarantees to protect your investment. However, if you're looking for a reliable workhorse that will last multiple seasons, your money is better invested in alternatives like the Lowa Renegade or Merrell Moab series.
The outdoor gear landscape continues evolving, and while the X Ultra 4 GTX isn't the bulletproof recommendation its predecessors were, it still has a place in the right hiker's quiver. Just go in with realistic expectations about longevity, and you won't be disappointed by the performance.
