Merrell Moab Speed 2 Mid Gore-Tex
For this season's top models, see our guide to the Best Hiking Boots.
During the first couple miles of my initial test hike, I thought the Moab Speed 2 Mid GTX felt stiff out of the box for a boot with a synthetic upper. By the third mile, though, it began to soften up and mold to my foot, and on my next hike, it felt broken in enough that I decided to break a cardinal rule of mine: Normally, I would never take a new boot on a backpacking trip with less than 15 miles of wear, but the Moab Speed 2 Mid felt so good that after those first two test hikes that I wore it on a four-day trek through the Grand Canyon. The result? I hiked out of the canyon without a single blister or hotspot, which might have been a first for me.
On trail, the Merrell Moab Speed 2 Mid GTX leverages its medium-thick cushioning, with plenty at the heel and toe, into a soft-and-squishy underfoot feel. I found it to be plenty comfy while remaining lighter than other hiking boots I’ve worn, including the Altra Lone Peak and the Keen Targhee. Compared to the Merrell Moab 3 Mid, the Moab Speed 2 broke in much faster and generally felt more flexible.
Typically, I prefer a stiff boot that’s stable at its base, yet still has some flexibility around the ankle. The Moab Speed 2 Mid performed in line with my preferences: I was easily able to trust the boot, and I felt secure when I was hauling a 35-pound pack through the Grand Canyon. Stability comes courtesy of a few different design factors, including a full-foot, fiberglass-reinforced polyamide layer that sits between the boot’s foam midsole and Vibram TC5+ outsole. The plate isn’t as rigid as a nylon shank, but still grants torsional support. The Moab Speed 2’s lacing system also helps, as it made it simple for me to increase tightness around the ankle—and thus stability—as I traversed off-kilter terrain or became tired and more prone to losing my balance. (If anything, this boot could have been a tad more stiff around the ankle.)
Compared to the Moab 3 Mid, which I’m also testing, the Moab Speed 2 is noticeably less stiff. Its lacing made up the difference in a lot of ways, but for hikers who don't like to lace tightly I think the lack of ankle support could be an issue when you’re carrying a multiday backpacking load.
The Moab Speed 2 Mid features a high-quality Vibram TC5+ outsole with 4-millimeter lugs, which lends itself to wonderful performance on rock (including wet slickrock) and packed dirt. However, these lugs are shorter than average for a hiking boot, so the Speed 2 gives up some traction in loose terrain like snow, wet leaves, and mud. That said, I did notice that the heel lugs provided a helpful “catch” when I was hiking downhill in steep and rocky terrain. Finally, it is worth noting that the Vibram TC5+ outsole prioritizes grip over durability with its soft build, and I noticed it starting to wear down after about 30 miles of use. Compared to hiking boots with firmer (yet less sticky) outsoles, the Moab Speed 2 won't last for as many miles.
Although the Moab Speed 2 appeared rugged at first glance—the nylon ripstop upper sports a collage of TPU overlays, and the midsole/outsole combo is chunky—the boot began to show signs of wear far more quickly than I anticipated. The exposed midsole foam had significant abrasions after 50 miles of testing, and the TPU details on the side are peeling and looking worn. Plus, as I mentioned above, the lugs on the outside edge of the boot have already begun to wear down and round off. So far the wear and tear has only affected aesthetics, not performance; but compared to more robust leather hiking boots, the Moab Speed 2 will certainly have a shorter lifespan.
The Merrell Moab Speed 2 Mid GTX has a TPU toe bumper, but it fails to extend far enough to the sides: Striking a rock close to your big or little toe is a recipe for some pain. The rest of the boot offers minimal protection, and I definitely felt rocks when I hit something on the side of my foot. Underfoot, at least, the protection granted by the tall midsole and polyamide plate isolates wearers from most terrain—but you’ll still likely feel the effects of a super-sharp rock.

Longevity
Choosing durable outdoor gear and keeping it in use for longer is one of the best ways to reduce environmental impact. Our proprietary longevity rating assesses factors like overall build quality, materials, fabric denier, component durability, and real-world performance. A green check indicates that we expect the product to be long-lasting relative to its peers, a yellow check mark indicates average longevity, and a red X indicates a product that may have a limited lifespan.
Recycled Materials
Recycled materials are prevalent in outdoor gear, with nylon, polyester, wool, and down among the most common, but the composition varies widely. A green check mark indicates the product is made with a substantial amount of recycled materials (100% recycled or the core fabric that makes up most of the product is recycled), a yellow check means it contains a moderate to small amount of recycled materials, while a red X means there are no recycled materials in the product.
PFAS-Free DWR
Durable water-repellent (DWR) finishes can contain PFAS (per- and polyfluoroalkyl substances). These highly persistent “forever chemicals” are used in outdoor gear for their strong resistance to water, oil, and heat, but are linked to environmental contamination and a range of health concerns. A green check mark indicates the product uses a PFAS-free DWR, while a red X means the DWR contains PFAS.
PFAS-Free Waterproof Membrane
The membranes used in waterproof products such as rain jackets, ski jackets, and shoes can contain PFAS (per- and polyfluoroalkyl substances). These highly persistent “forever chemicals” are valued for their resistance to water, oil, and heat, but are linked to environmental contamination and a range of health concerns. A green check mark indicates the product’s waterproof membrane is PFAS-free, while a red X means it contains PFAS.
Bluesign Approved
Bluesign Technologies, based in Switzerland, operates a third-party textile management system that ensures materials are manufactured to strict environmental, chemical, and worker safety standards. A green check mark indicates a product is either a Bluesign Product (contains at least 90% Bluesign-approved fabrics and 20-30% Bluesign-approved accessories) or features a significant amount of Bluesign-approved materials. A yellow check mark means it uses some Bluesign-approved materials but less than the aforementioned category, and a red X means there are no Bluesign-approved materials in the product.
Responsible Manufacturing
This criterion evaluates a brand’s commitment to fair wages, safe working conditions, and reducing environmental impact through certifications and programs like Fair Trade Certified, Fair Wear Foundation, Worldwide Responsible Accredited Production (WRAP), and the Fair Labor Association, while also recognizing brands that manufacture primarily in the U.S. or Europe under strict labor and environmental regulations. A green check mark indicates a brand meets our responsible manufacturing criteria, while a red X means it does not.
Recycled and/or Reduced Packaging
Packaging can add significant waste to outdoor gear purchases, so many brands work to reduce its impact by using recycled materials, incorporating Forest Stewardship Council-certified paper products, and minimizing plastic and paper use. A green check mark indicates a brand uses recycled or reduced materials across all of its packaging, a yellow check indicates moderate or limited use of recycled or reduced packaging, and a red X indicates the brand does not make either of these efforts.
Resale and/or Recycling Services
Resale and recycling programs help keep outdoor gear in circulation longer and out of landfills, ranging from trade-in resale platforms that offer store credit to take-back initiatives that recycle products at the end of their usable life. A green check mark indicates a brand offers both resale and recycling programs, a yellow check mark indicates it offers one or the two, and a red X indicates it offers neither.
Carbon Footprint Tracking
This criterion evaluates whether a brand measures, reports, and works to reduce its greenhouse gas emissions using established frameworks such as the Higg Index, Greenhouse Gas Protocol, or The Change Climate Project. A green check mark indicates a brand publicly reports greenhouse gas emissions data, sets clearly defined reduction targets, and uses established tracking frameworks such as Higg or The Change Climate Project. A yellow check mark indicates the brand tracks emissions and outlines reduction goals but provides limited data, lacks science-based verification, or does not clearly report progress. A red X indicates the brand does not appear to track greenhouse gas emissions or provides so little information that its efforts cannot be verified.
Annual Impact Report
Annual impact reports provide transparency and accountability by outlining a brand’s sustainability efforts across areas such as material sourcing, greenhouse gas emissions, waste, water use, supply chains, and packaging. A green check mark indicates a brand publishes a detailed, brand-specific impact report that closely aligns with our sustainability criteria and leaves little room for ambiguity. A yellow check indicates a brand provides some relevant sustainability reporting but lacks detail in key areas or is covered only briefly within a parent company report. A red X indicates a brand does not regularly publish an impact report.
The Moab Speed 2 Mid GTX is a lightweight hiking boot; at 1 pound 8.7 ounces for the women’s pair, it positions itself weight-wise right in the middle of competitors that you can use for either day hiking or light backpacking duty. For comparison’s sake, Merrell’s traditional Moab 3 Mid checks in at 1 pound 12.9 ounces for the women’s pair, while the midweight Lowa Renegade is much heavier at 2 pounds 2.2 ounces. The Moab Speed 2 Mid isn’t a boot that will weigh you down (unless you’re looking to go light and fast, in which case a trail running shoe makes more sense), but at the same time, it’s not meant for particularly rough terrain or missions that require a burdensome pack.
Waterproof Liner
Gore-Tex liners are the highest-performing waterproof constructions on the hiking boot market, and the one in the Moab Speed 2 lives up to its reputation. I tested it in several stream crossings and never felt even a touch of dampness. I don’t often use waterproof boots, but I did have a pair of Altra’s that were waterproof, and they felt similar in terms of waterproof capabilities. However, the Moab Speed 2 was more breathable in high temps: The majority of my Grand Canyon hike was done in 70- to 85-degree Fahrenheit weather, and this boot managed to still feel comfortable in the heat. It definitely warmed up when I was working hard on the uphill, but it felt comparable to non-waterproof hiking boots I’ve used.
Lacing System
This is a standard lace-up boot, with the ankle joint lace placed a bit farther back than the rest for added tightening and stability. A metal hook keeps the final lace crossing in place, and makes the boot easy to batten down. This system keeps a solid hold and I never needed to retighten throughout the day.
I typically fall right between a women’s size 8 and 8.5, with a thin heel and wide midfoot and toes, and often end up sizing up due to issues with narrow toe boxes. In this case, though, I tested the Merrell Moab Speed 2 Mid in a size 8 and it was perfect. The toe box was wide enough for my comfort, but not too wide where my toes were moving around and rubbing enough to cause blisters (I’ve had that issue with Altras in the past). The midfoot felt snug but not tight, even when my feet swelled after a long day. The heel also fit well, not too constricting but not so loose that my heel moved around and I got hotspots. Overall, this is one of the best-fitting hiking boots I’ve worn.
Merrell Moab 3 Mid Waterproof ($150): Traditional Merrell
I usually reach for the Merrell Moab 3 Mid Waterproof for short hikes, and while they share part of their name the Moab Speed 2 has some key differences. First is durability: The Moab 3 has an upper made from pigskin leather and thick mesh, which is much longer-lasting than the Moab Speed 2’s relatively flimsy synthetic material. It’s also geared towards heavier loads and longer hikes, with a molded nylon arch underfoot and a midsole with more rebound (but a less-cushy feel). The Moab 3 is also heavier and less-breathable, but it costs $30 less (notable given the disparity in durability) and has increased forefoot and underfoot protection. Finally, while we’re usually loath to harp on aesthetics in hiking boots, the Moab 3 is an especially nerdy looking boot, which might matter if performance doesn’t tip the scales.

On Cloudrock Mid WP ($220): Similar Design But Tradeoffs Galore
The first difference you’ll notice about the On Cloudrock Mid is its price ($220), which seems fairly ridiculous given its on-trail performance tracks closely with the Moab Speed 2. The Cloudrock offers a bump in comfort and perhaps stability, but its lugs are shallower than the Moab Speed 2’s and durability is about the same. This boot has more of a trail running shoe-inspired design than the Moab Speed 2, and so grants a more natural stride. While the Cloudrock might support a heavier pack, it’s not by much, and both of these boots aren’t made for anything more than a four-day jaunt. Given the price discrepancy, though, we’d probably pick the Moab Speed 2. For more, read our review of the On Cloudrock Mid.
Merrell goes modern with the Moab Speed 2, combining lightweight design, plush cushioning, and unexpectedly strong support. You sacrifice some protection and durability, but it’s hard to beat this boot’s comfortable and athletic feel.

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 looking to move fast and light without a whole lot of compromises, the Merrell Moab Speed 2 Mid GTX is an excellent option. This boot is more than just a souped-up trail runner—it offers impressive underfoot stability, true above-the-ankle support, and a premium Vibram outsole that's in its element on rocky terrain. And like most of Merrell's footwear, comfort is a real highlight. The boot's lack of foot protection is a potential buzzkill if you consistently travel off-trail, and its durability does fall noticeably short of burlier leather designs. But if speed is the name of your game but you want a big step up from a trail runner, take a closer look at the Moab Speed 2 Mid.
