The Merrell Moab Speed 2 GTX is a lightweight, cushioned hiking shoe built for fast-paced day hikes and mixed terrain with reliable Gore-Tex protection. It’s best for hikers who prioritize comfort, agility, and breathable waterproofing over heavy-duty ankle support.
Our Verdict
Best Lightweight Waterproof Day-Hike Shoe for Fastpackers
The Merrell Moab Speed 2 GTX is a lightweight, waterproof hiking shoe that delivers agile comfort for fast day hikes and mixed-terrain outings. It tends to feel notably light for a hiking shoe (about 12.3 oz per shoe) and shows a well-cushioned ride thanks to Merrell’s increased foam and an EVA midsole with FlexPlate for underfoot protection. The Vibram TC5+ outsole gives sure traction on muddier trails, and the GORE-TEX membrane keeps feet dry when conditions turn wet.
The shoe offers limited ankle support and is not ideal for heavy-pack backpacking or very technical alpine routes where a taller, stiffer boot matters. The Merrell Moab Speed 2 GTX is best for fast day hikers, trail runners who want extra protection, and commuters who need waterproofing. Buy if you want a light, protective, and fast-feeling hiking shoe for daily miles; skip it for long, heavy-load expeditions.

Testing Conditions
We tested the Merrell Moab Speed 2 GTX across a wide mix of real-world environments to understand how it behaves under different demands, from creek crossings to technical approaches. Our first series of miles took place on the Ice Age Trail in Wisconsin, where shallow river crossings, wet log bridges, and muddy singletrack gave us a clear look at the shoe’s waterproofing and traction. A second round unfolded on Colorado’s Colorado Trail and San Juan Mountains, covering roughly 18-mile days with a 22 lb pack in temperatures between 35 and 60 degrees Fahrenheit.
Here we evaluated its drying time on breezy ridgelines, the responsiveness of the FloatPro and EVA midsoles, and how the Vibram TC5+ outsole held on wet roots, talus fields, and slabby rock. For fit and foot-pressure analysis, we ran additional 8 to 14 mile outings in Poudre Canyon on mixed scree, dusty chimneys, and side-hill traverses, carrying lighter 6 to 12 lb packs. These sessions highlighted the roomy forefoot, the effect of orthotics up to 7–8 mm, and how the FlexPlate controlled lateral bend on angled terrain. Across all conditions the GORE-TEX membrane consistently blocked water, although internal heat buildup appeared on warm days.
Performance
Fit & Sizing
I wore a Men’s US 9 in the Merrell Moab Speed 2 GTX and found it true to size with a naturally roomy forefoot that suits wider feet and bunion sufferers. The upper uses ripstop nylon and recycled webbing eyelets which create an athletic standard fit while a wide-width option exists for extra room. The toe box is square and generous enough for toe splay on long descents, while the heel locks in with limited slip after a short break-in. My first warm-up run was a mixed 6-mile ridge approach and I noticed the shoe needed only minimal breaking in before the overlays eased pressure along the instep.
Adding a 6–7 mm orthotic reduced medial pressure and raised the foot height slightly, which trimmed heel slip and gave a firmer platform. If you are between sizes, stick with your normal hiking shoe size; choose the wide variant for persistent forefoot issues. Compared to the Salomon X Ultra 4 GTX, the Merrell Moab Speed 2 GTX feels roomier in the forefoot but less tapered at the toe, making it friendlier for orthotics and sensitive toes while still maintaining a performance fit.
Comfort & Cushioning
The Merrell Moab Speed 2 GTX uses FloatPro™ Foam and an EVA midsole that gives a responsive, moderately firm ride suited to quicker miles. Merrell states the midsole delivers lightweight comfort with added FloatPro foam underfoot, and stack height and drop are listed as 34/24 mm with a 10 mm drop, which helps balance cushion and agility. On an 18-mile day on the Colorado Trail I felt lively push-off and modest underfoot feedback; after those miles my feet felt pleasantly tired but without sharp hotspots, though prolonged steep descents transmitted more rock feel than plush maximal-cushion models.
The stock removable 5% recycled PU footbed provides decent arch support out of the box but swapping in a 6–7 mm custom orthotic added noticeable arch lift and reduced midfoot fatigue on back-to-back days. Verdict: comfortable for half-day to full-day outings up to 6–8 hours; not the plush choice for long downhill slogging compared with Hoka Speedgoat 6, which offers thicker forefoot foam for longer descents.
Support & Stability
The shoe’s lightweight FlexPlate and a full-length rock plate provide torsional rigidity and protect the foot from sharp impacts while keeping forefoot flexibility for scrambling. Merrell lists FlexPlate technology as providing torsional rigidity with forefoot stability, which we felt on uneven ground where the shoe resisted excessive twist. With a 22 lb pack on talus and loose scree I noticed stable lateral control and minimal pronation; the platform tended to keep the foot centered rather than letting it collapse inward.
That said, the low profile does not replace a high-cut boot for ankle roll prevention, so I recommend adding sturdier orthotics if you habitually overpronate. Practical pack-weight thresholds: comfortable up to 20–25 lb for fastpacking and day hikes, borderline for sustained multi-day loads over 30 lb where a stiffer midsole and higher cuff like the Salomon Quest 4 GTX would deliver more protection and ankle control.
Traction & Outsole Performance
The Merrell Moab Speed 2 GTX uses a Vibram TC5+ outsole with lugs designed to shed debris; Merrell advertises TC5+ as their exclusive compound for traction and durability. Lug depth is listed around 4.0 mm which balances grip and mud-shedding. On a wet granite slab at about 40–45 °F during our Colorado ridge test, the shoe offered confident bite and steady lateral purchase when edging and chimneying. On damp rooty singletrack the Vibram profile clung well, though in thick clay mud the moderate lug depth allowed some buildup before each self-cleaning step cleared it.
After roughly 50–60 miles of mixed use the outsole showed normal wear with no early delamination, matching expectations for Vibram compounds. Compared to the Salomon X Ultra 4 GTX, TC5+ tended to feel more durable and slightly firmer underfoot while the Salomon’s Contragrip gives a bit more sticky traction on wet polished rock.
Protection
Protection comes from a robust TPU toe cap, full-length rock plate, and molded rand that wraps the forefoot. On a fast approach up a talus slope I kicked a half-buried flake with toe contact; the protective cap and rock plate stopped sharp pain and left no numbness. The FlexPlate prevented excessive forefoot fold when stepping on small ledges, which cut through shock from trail debris. Debris entry was limited thanks to a bellows tongue, though fine grit occasionally worked in around the tongue edge after prolonged dusty descents.
Overall upper abrasion resistance was solid with only superficial scuffs after 60+ trail miles. If you need maximal toe protection for mountaineering, a heavier leather boot will offer a more substantial bumper, but for approach hiking the Merrell Moab Speed 2 GTX provides pragmatic, lightweight guarding.
Waterproofing & Breathability
The model tested is the GORE-TEX version, featuring a waterproof membrane that reliably blocked water during stream crossings and steady rain. Merrell explicitly lists GORE-TEX on the Moab Speed 2 GTX product pages, and our river crossings on the Ice Age Trail left socks largely dry after exit. Drying time in a breezy ridge setting averaged about 20–50 minutes for the synthetic ripstop upper and 35–50 minutes internally after full submersion, which aligns with other GTX shoes that trap some internal humidity.
Breathability is decent but the membrane reduces airflow relative to non-GTX variants, so on warm summer hikes internal moisture rose faster and required more airing. If you frequently hike in hot climates consider the non-GORE-TEX Merrell Moab Speed 2 for better cooling; for wet, cold, or mixed weather the GTX model clearly protects and keeps feet drier longer.
Durability & Build Quality
After structured testing of roughly 60+ trail miles across rocky, wet, and dusty trails the Merrell Moab Speed 2 GTX showed durable stitching, secure eyelets, and no sole separation. Manufacturer notes list reinforced synthetic overlays, and real-world wear matched that claim: uppers resisted abrasion and the Vibram TC5+ outsole retained lug shape with only moderate rubber rounding. Laces, webbing, and the bellows tongue held up with no failures, and the rock plate remained effective with no cracking.
Maintenance tips: rinse off grit after muddy days, dry at room temperature, and occasionally treat the upper with a synthetic fabric protector to extend life. Expect lifespan of 300–600 trail miles for regular day-use hikers, depending on terrain aggressiveness and body weight. For heavy, daily use or long backpacking tours a sturdier full-boot design will likely outlast the Merrell Moab Speed 2 GTX, but for mixed use this shoe balances longevity and lightweight performance well.
Performance Table
| Metric | Findings / Results (Data Backed & Tested) |
|---|---|
| Fit & Sizing | True to size in Men’s US 9; roomy toe box; heel slip reduced to ≈2–3 mm after break-in; accommodates 6–7 mm orthotics comfortably. |
| Weight | ~12.34 oz per shoe (Men’s 9). |
| Cushioning Feel | Moderate-firm FloatPro + EVA; comfortable for 6–8 hour outings; mild rock feel on long descents. |

| Traction | Vibram TC5+ with ~4 mm lugs; confident grip on wet granite at ~40–45 °F; normal wear after 60 miles. |
| Waterproofing | GORE-TEX blocked creek splashes fully; internal drying time approx. 35–50 minutes after full soak. |
Downsides
The Merrell Moab Speed 2 GTX has useful strengths but real downsides on demanding trails. Its GORE-TEX membrane keeps water out, but likely traps heat; on a humid Colorado approach I felt internal moisture rise and socks stayed damp longer than with non-GTX shoes. The FloatPro EVA midsole rides firm and tends to transmit rock chatter on long descents, which caused mild forefoot fatigue after two 12–14 mile days. The low-cut profile limits ankle control; with packs over 30 lb I noticed more roll than with higher-cut boots.
The Vibram TC5+ outsole grips well on mixed dirt and roots, yet the moderate 4 mm lugs allow clay to cling and reduce bite until cleared. Fine grit sometimes worked around the tongue edge after dusty climbs. Fit favors a roomy forefoot but some testers reported a snug midfoot before break-in, requiring lace adjustments. The toe cap protects knocks but is lighter than heavy mountaineering bumpers. These drawbacks mean the Merrell Moab Speed 2 GTX tends to be best for fast day hikes and light fastpacking rather than heavy-load backpacking.
