Who should buy

In our opinion, it's hard to go wrong with the top picks among hiking boots if you are after the following:

  • a solid boot for hiking moderate terrain with an average-sized pack
  • Flexibility / Stiffness
  • a mid-cut boot with world-class Gore-Tex waterproofing (ready for ankle-deep creeks and puddles)

Who should NOT buy

The KEEN Targhee III Waterproof Mid is a fantastic all-purpose boot but it has its limitations when the hiker's demands get more specific.

If you want all the support and stability a mid-cut boot can provide (for backpacking especially), consider the Salomon X Ultra 4 Mid GTX instead. It is one of the sturdiest boots in the same price range and has better grip for technical and muddy terrain.

If you want a nimbler companion for lighter and speedier hikes (with a lighter pack), look into the Merrell Moab Speed Mid GTX.

And if you want all the benefits of the KEEN Targhee III Waterproof Mid minus the high collar, the low-top Moab 3 GTX shoe is always available too! And it's $15 cheaper.

We can confirm that it packs enough impact protection for long hours on the trail. Our feet felt very well taken care of throughout the hike.

Measuring the heel stack of this Merrell boot, we got a reading of 36.1 mm on our caliper. It is notably taller than the Flexibility / Stiffness (31.1 mm) and is on par with the low-top Moab 3 GTX shoe (36.7 mm).

The Moab Mid 3 GTX doesn't skimp on forefoot protection either.

There is 22.6 mm of sole material separating the ball of your foot from the trail. It is an average forefoot stack reading for hiking boots but we found that it does a great job muting out rocks and roots underfoot.

Drop

In its official specs, Merrell lists 11.5 mm as the boot's heel-to-toe drop. However, our lab stack measurements showed it to be slightly higher (13.5 mm).

Midsole width - forefoot.

A heel-to-toe drop within the 10-14 mm range is optimal for entry-level hikers as it elevates the heel above the toes just enough to take the pressure off the Achilles, especially when a heavier load is involved.

Midsole softness

Note: a low durometer measurement equals a soft material, whereas a high measurement means it's firm.

The KEEN Targhee III Waterproof Mid feels nice and comfortable but its cushioning can't be categorized as plush.

Showing 32.8 HA on our Shore A durometer, the boot's midsole foam turns out to be 20% firmer than the average.

top picks among hiking boots Midsole softness

However, it feels a little softer under the heel than the static reading might suggest. This is thanks to the Merrell Air Cushion technology which is comprised of a softer piece of foam (24.6 HA) and a hollowed-out section beneath it.

We found it to be a nice way to add some comfort to the ride without compromising the boot's firmness for stability.

Considering the boot's warm and waterproof construction, it only makes sense that it is meant for the colder season. But how does its cushioning behave when the temperatures drop? Let's find out.

We mimicked winter conditions with the help of a freezer for 20 minutes. After that, we repeated the durometer measurement and discovered that the boot's midsole foam firmed up rather moderately (by 14.5%).

But compared to other hiking boots, it did get pretty firm showing 37.5 HA on the tool.

Insole thickness

The KEEN Targhee III Waterproof Mid amplifies underfoot comfort by adding a well-padded insole. We found it to be 6.0 mm thick in the heel which is a typical measurement for hiking boots.

Stability

Lateral stability test

For a mid-cut boot intended for moderate hiking conditions, we believe that the top picks among hiking boots has excellent lateral stability.

Even if you are a beginner hiker with mild overpronation, you will find ample support in this Merrell boot. It may lack the stability needed for multi-day hikes with a heavy backpack but it will keep you covered for a single-day adventure with a medium pack.

Torsional rigidity

With a stiff nylon shank embedded into its midfoot section, this Merrell boot has a good amount of torsional rigidity to prevent the wearer's ankle from collapsing. We never felt tippy during the wear tests.

When we tried to twist the boot in our manual test, the give was very minimal. Thus, it got a fairly high stiffness score of 4 out of 5.

Heel counter stiffness

Our heels and ankles also felt secure inside the KEEN Targhee III Waterproof Mid. The boot offers a great deal of ankle support through its raised and well-padded collar as well as the stiff heel counter.

Excellent grip on hard terrain.

As you can see, this Merrell boot didn't get the highest possible scores for stiffness but this is what helped it feel a little more comfortable on foot.

One more bonus point for comfort.

Weight

Based on our personal experience, the top picks among hiking boots doesn't feel particularly heavy but it does feel substantial on foot.

Tipping the scale at 17.5 oz (495g), it is even an ounce lighter than the average hiking boot in our lab.

top picks among hiking boots Weight

Compared to other mid-cut waterproof hiking boots in the same price range ($160-$180), the KEEN Targhee III Waterproof Mid sits between the heavier Flexibility / Stiffness (18.2 oz/515g) and the lighter Salomon X Ultra 4 Mid GTX (14.5 oz/412g).

Even though we have no complaints about the boot's weight, some hikers may find it too burly for their outdoor activities. Speed hiking, for example, calls for much lighter and more nimble boots like the Merrell Moab Speed Mid GTX (11.7 oz/332g).

Breathability

Since we are reviewing the waterproof GTX (GORE-TEX) version of the Moab 3 Mid, breathability is not to be expected here.

The boot's thick watertight construction didn't let any air pass through the upper, as our smoke-pumping test above shows. Without a flicker of doubt, we gave it the lowest breathability score of 1 out of 5.

Don't be tricked by the mesh lining - it is only the topmost layer of the boot's upper. The waterproof membrane is hiding right beneath it.

For warmer weather, you should get the non-waterproof version of the boot instead (and it's even $40 cheaper).

Waterproofing

The boot's waterproofing, on the other hand, is stellar! The GTX membrane has been up to the task as we submerged the Moab 3 Mid in ankle-deep puddles and creeks. We can also confirm that this Merrell boot can handle moderate rain, slush, and snow.

top picks among hiking boots gore-tex membrane

As long as the water doesn't spill over the boot's collar and seep inside the boot, your feet are going to stay dry and warm.

But here is the caveat - once you rip that membrane, the whole boot loses its waterproofing capacity. Does the upper of this Merrell boot have enough wear resistance to prevent that? Let's find out.

Durability

Toebox durability

Even though the boot features reinforcements all over the upper (rubber toe cap, toe rand, and suede overlays), it still has quite a few areas with exposed mesh. Unfortunately, that material does not stand strong against aggressive wear and tear.

top picks among hiking boots toebox

If you frequently slash your boots against rocky ridges or wade through sharp bushes, this textile is going to give up rather quickly.

To mimic the abrasion from hours of trail wear, we applied a Dremel with a sandpaper tip to the shoe's toebox mesh. The speed (5K RPM) and pressure (3.2N) remained consistent. After 12 seconds of exposure, the tool completely burned through the top layer of mesh and notably scratched the inner lining. Unfortunately, waterproofing is no longer guaranteed after this sort of damage.

top picks among hiking boots Toebox durability comparison

Assessing the toebox durability of the KEEN Targhee III Waterproof Mid under these conditions, we couldn't rate it any higher than 3 out of 5. This is slightly better than the toebox of the low-top Moab 3 GTX shoe (on the right) where the tool got all the way through the upper material.

If you are worried about tearing your hiking boots too soon, have a look at the Salomon X Ultra 4 Mid GTX. This boot comes from the same price range but the wear resistance of its synthetic upper is on another level.

Heel padding durability

As our next Dremel test shows, the inner lining of the KEEN Targhee III Waterproof Mid happens to be much more wear-resistant than the boot's outer mesh.

Following 4 seconds of drilling the textile at 5K RPM speed, you can't even tell that this Merrell boot was touched with sandpaper. Even the more expensive Anacapa boot (on the right) faltered in the same test.

Thus, we proudly rate the boot's heel lining durability with the maximum score - 5 out of 5!

Outsole hardness

If you check our The KEEN Targhee III Waterproof Mid showed great long-distance capacity during our wear tests, you will see that nearly every boot features a Vibram rubber outsole. It's like a label of higher quality in the realm of outdoor footwear.

top picks among hiking boots vibram

The top picks among hiking boots also uses Vibram's TC5+ rubber which was exclusively developed for the brand.

Let's see if it meets our high-set expectations.

top picks among hiking boots Outsole hardness

For starters, we checked the hardness of the TC5+ rubber with a Shore C durometer and it showed a solid high reading of 85.0 HC. This is quite reassuring.

Outsole durability

However, when we turned to the Dremel in our abrasion resistance test, we found that the shoe's Vibram rubber was not as special as we had anticipated.

Having drilled the shoe's rubber outsole for 22 seconds at 10K RPM speed, we noticed that the sandpaper carved out a pretty notable dent in the outsole.

Measuring it with a tread gauge confirmed our observation showing a slightly deeper than average reading of 1.2 mm.

While this is not catastrophic, it makes this Merrell boot less likely to outlast its counterparts when it comes to outsole durability.

Lug depth

First of all, we are happy to report that our caliper measurements confirmed the brand specs - the boot's lug depth is precisely 5.0 mm!

The grip offered by these deep treads and the Vibram TC5+ rubber did not falter during our wear tests.

The KEEN Targhee III Waterproof Mid kept us surefooted as we navigated rocks and creeks and stepped on wet grass and mossy logs.

top picks among hiking boots outsole

However, we wouldn't recommend this Merrell boot for squelching through mud and soft terrain. Even though its lugs are deep, they are not sharp and toothy enough for these conditions. The Salomon X Ultra 4 Mid GTX has a more aggressive treading for challenges like that.
