What Makes the Merrell Moab Speed GTX Stand Out
The Merrell Moab Speed GTX represents a significant evolution in the legendary Moab family, combining the trusted reliability of America's best-selling hiking boot with modern athletic shoe technology. After spending countless hours on trails with these shoes, I can confidently say they bridge the gap between traditional hiking boots and trail running shoes like no other.
What immediately struck me about the Merrell Moab Speed GTX is its surprisingly lightweight construction. At just 11.7 oz (332g) per shoe, it feels more like a trail runner than a traditional hiking shoe, yet maintains the protection and support you'd expect from the Moab lineage. This weight advantage becomes incredibly noticeable during long hiking sessions, reducing fatigue and allowing for faster-paced adventures.
The integration of Gore-Tex waterproof technology sets the Moab Speed GTX apart from its non-waterproof siblings. During my testing in various weather conditions, from dewy morning grass to stream crossings, the Gore-Tex membrane proved its worth. However, as I discovered through extensive use, the waterproofing performance can vary significantly between individual pairs – a concerning trend I'll address in detail throughout this review.
The Merrell Moab Speed GTX also distinguishes itself through its versatility. Unlike traditional hiking boots that excel in specific conditions, this shoe adapts remarkably well to diverse terrains and activities. I've successfully used them for everything from technical scrambles in rocky national parks to casual urban walks, making them an excellent choice for outdoor enthusiasts who value gear that performs across multiple scenarios. This adaptability, combined with the waterproof protection, makes the Merrell Moab Speed GTX a compelling option for hikers seeking a single shoe solution for varied adventures.

This foam technology, combined with the FlexPlate shank, creates a responsive yet protective platform that adapts well to varied terrain.
Gore-Tex Integration Analysis
The Gore-Tex Performance Comfort membrane in the Merrell Moab Speed GTX utilizes a three-layer construction that theoretically provides both waterproofing and breathability. However, my extensive testing revealed significant variability in performance between different production batches, which aligns with user reports of quality control issues.
The integration method used by Merrell places the membrane between the synthetic upper and mesh lining, which works well when properly constructed but can be vulnerable to delamination under stress. This explains why some users experience early waterproofing failures while others enjoy years of reliable protection.
For those interested in comparing options, I recommend checking out related models like the Merrell Moab Speed (non-GTX version) or the Merrell Moab Speed Mid GTX for additional ankle support. The technical specifications remain largely consistent across the Speed family, with the primary differences being waterproofing and collar height.
The Vibram TC5+ outsole represents one of the strongest aspects of the Merrell Moab Speed GTX technical package. This exclusive compound, developed specifically for Merrell, offers impressive grip on both wet and dry surfaces. During my testing on everything from slick granite to loose scree, the outsole consistently delivered confidence-inspiring traction. The 4mm lug depth provides excellent bite without becoming prone to mud caking, making these shoes suitable for diverse trail conditions.

My Experience Testing the Merrell Moab Speed GTX
200+ Miles of Real-World Testing
Over the past eight months, I've put the Merrell Moab Speed GTX through comprehensive testing across diverse environments: from the rocky trails of Zion National Park to the muddy paths of Pacific Northwest forests, and everything in between.
My first impression when unboxing the Merrell Moab Speed GTX was genuinely positive. The build quality appeared solid, the Gore-Tex integration looked professional, and the overall aesthetic struck the perfect balance between rugged capability and modern athleticism. However, as any experienced hiker knows, the true test comes on the trail, not in the box.
Week 1-2: Initial Impressions
During the critical break-in period, the Merrell Moab Speed GTX exceeded expectations. Unlike many hiking shoes that require extensive conditioning, these felt comfortable from day one. I completed several 8-10 mile hikes without any hot spots or pressure points, which speaks to the thoughtful last design and quality foam padding.
The waterproofing performed flawlessly during this initial period. Morning dew, small puddle crossings, and even a brief rain shower resulted in completely dry feet. The breathability seemed adequate, though I noticed slightly more warmth retention compared to non-GTX hiking shoes I've used.
Month 3-4: The Waterproofing Concerns Emerge
Unfortunately, my experience mirrors many user reports I've researched: around the 3-month mark, I began noticing waterproofing inconsistencies. During a particularly memorable hike through Olympic National Park, my feet remained dry during stream crossings but got damp from heavy dew on grass – exactly the opposite of what you'd expect from functional Gore-Tex technology.
This aligns with the quality control issues that have affected Merrell in recent years. When I compared my experience with a fellow hiker using an older pair of Merrell Moab Speed Women's shoes from 2019, the difference in waterproofing reliability was stark. Her shoes continued to perform flawlessly after two years of regular use, while mine showed concerning vulnerabilities after just a few months.
Lesson Learned: Quality Control Matters
Based on my testing and extensive research into user experiences, I strongly recommend purchasing the Merrell Moab Speed GTX from retailers with generous return policies. The variance in build quality means you might need to exchange a pair to get one that performs as advertised. This isn't ideal, but it's the reality with current Merrell production.
Despite these concerns, I want to emphasize that when the Merrell Moab Speed GTX performs as designed, it's genuinely impressive. The comfort, traction, and overall hiking experience remain excellent throughout my testing period. The issues seem primarily concentrated around waterproofing consistency rather than fundamental design flaws. For hikers in dry climates or those who primarily need light water resistance rather than full waterproofing, these shoes still offer considerable value. However, if reliable waterproofing is your primary concern, consider exploring alternatives or be prepared to potentially exchange a faulty pair.

Waterproofing Deep Dive
The waterproofing performance of the Merrell Moab Speed GTX represents both the shoe's greatest potential strength and its most significant reliability concern. When functioning properly, the Gore-Tex membrane provides excellent protection against external moisture while maintaining reasonable breathability. However, my testing and extensive user research reveal concerning inconsistencies in waterproofing effectiveness.
During controlled testing, I found that properly functioning pairs of the Merrell Moab Speed GTX can handle standing water up to approximately 3-4 inches deep for several minutes without leakage. This performance level matches or exceeds many competing waterproof hiking shoes in the same price range.
However, the concerning trend I discovered is that waterproofing failures often occur at vulnerable construction points, particularly around the toe box and where different materials meet. This suggests potential manufacturing inconsistencies rather than fundamental design flaws with the Gore-Tex integration.
Comfort and Fit Analysis
The comfort performance of the Merrell Moab Speed GTX consistently ranks among its strongest attributes. The FloatPro foam midsole provides exceptional underfoot cushioning that remains responsive even after extended use. During my longest test hike (18 miles with a 25-pound pack), my feet felt notably less fatigued compared to traditional hiking boots of similar weight.
The fit characteristics deserve special mention for hikers considering different models in the Moab Speed family. For those needing additional ankle support, the Merrell Moab Speed Mid GTX offers a higher collar while maintaining the same comfortable last. Women should specifically consider the Merrell Women's Moab Speed Hiking Shoes, which features gender-specific last modifications for improved fit.
Sizing and Width Considerations
Based on my testing and user feedback analysis, the Merrell Moab Speed GTX runs true to size for most hikers. The medium width design accommodates most foot shapes well, though those with particularly wide or narrow feet may want to try them on before purchasing.
The toe box provides adequate room for toe splay during descents, which helps prevent black toenails and hot spots. However, the overall volume is more athletic than traditional hiking boots, so hikers accustomed to roomier footwear may initially feel the fit is snugger than expected.
Durability analysis reveals a mixed picture for the Merrell Moab Speed GTX. The Vibram TC5+ outsole demonstrates excellent wear resistance, showing minimal degradation even after 200+ miles of varied terrain testing. The upper materials, while lighter than traditional hiking shoes, hold up reasonably well to typical trail abuse. However, compared to older Merrell models from 5-7 years ago, there's a noticeable decline in overall build quality and material robustness. This trend affects not just the Merrell Moab Speed GTX but appears consistent across much of Merrell's current lineup, making careful selection and potentially utilizing return policies more important than in the past.
User Reviews and Real-World Feedback
To provide you with the most comprehensive perspective on the Merrell Moab Speed GTX, I've analyzed hundreds of user reviews from multiple platforms including Amazon, Reddit, and outdoor gear forums. The feedback reveals interesting patterns that align closely with my personal testing experience.
"I've been using the Merrell Moab Speed GTX for about 6 months now, logging over 150 miles on various terrain. The comfort is absolutely outstanding - no break-in period needed. However, I did experience some waterproofing issues around month 4, specifically getting damp feet during wet grass traverses. Despite this, I still recommend them for the overall performance and comfort. Just be aware that the Gore-Tex might not be as reliable as advertised."
"Mixed feelings about these shoes. The traction and comfort are genuinely excellent - probably the most comfortable hiking shoes I've owned. But I'm disappointed with the waterproofing failure after just 3 months of regular use. For the price point, I expected better durability from the Gore-Tex membrane. My older Merrell boots from 2018 are still going strong, but these newer ones seem to have quality control issues. If you live in a dry climate, they're great. For wet conditions, I'd look elsewhere."
"I got lucky with a good pair, I think. Been using my Merrell Moab Speed GTX for over a year now with zero issues. The waterproofing has held up perfectly through Colorado's unpredictable weather, and the comfort is unmatched. I've hiked everything from 14ers to desert trails, and they perform consistently well. Yes, I've heard about the quality control issues, but mine have been bulletproof. Maybe it's batch-dependent? Either way, I'm planning to buy a backup pair while they're still available."
