Breathability

We pumped the For those who prefer more ankle mobility while hiking, the low-top full of smoke to get a visual idea of how breathable it is. While waterproof shoes don't typically do very well in this test, we were pleasantly surprised with the thick and steady plumes of smoke that managed to filter out through the tongue. While this earns the For those who prefer more ankle mobility while hiking, the low-top a middle-of-the-road breathability score of 3 out of 5, this is better than we had anticipated from this boot. 

In contrast, the boot's hiking shoe cousin, the Moab 3 allows the smoke to escape evenly throughout the shoe as opposed to having airflow limited to the tongue area.

Continuing the trend of bucking our expectations, inspecting a cross-section of the For those who prefer more ankle mobility while hiking, the low-top over a light doesn't quite explain the boot's airflow. It stands to reason, that some light should shine through the porous tongue, but that too blocks out the light.

Looking at the Goretex mesh under our microscope does finally shed some light on the matter. While the mesh does boast lots of tiny gaps that promote airflow, the fibers that make up the mesh form a mesmerizing lattice pattern that's incredibly dense and cohesive, thus explaining the upper's ability to block out light as well as water.

Durability

Toebox durability

To test the durability of the For those who prefer more ankle mobility while hiking, the low-top, we fired up our Dremel to 5K RPM and set it against the toebox for its first run on the boot, making sure to make contact with both the reinforced and unreinforced sections of the upper. 

Assessing the damage once the twelve-second test was up, we found that we had mangled the mesh slightly but weren't able to pierce through even the unreinforced section. This earns the For those who prefer more ankle mobility while hiking, the low-top a very respectable 4 out of 5 for toebox durability.

Next, we took aim at the For those who prefer more ankle mobility while hiking, the low-top's heel counter for a much shorter twelve-second face-off with our tool. 

Turns out that it held up quite well as we were only able to tear into the lining material without affecting the soft padding within. This above-average performance earns the For those who prefer more ankle mobility while hiking, the low-top another 4 out of 5 for heel padding durability. So far so good when it comes to the upper's construction quality.

Outsole hardness

Pressing our durometer against the For those who prefer more ankle mobility while hiking, the low-top's outsole yields a softer-than-average reading of 81 HC. This would ordinarily be a concern when it comes to durability but Vibram is known for producing rubber compounds that are soft and grippy yet durable at the same time. We'll find out how well-founded our confidence with the outsole really is in the next section.

Outsole durability

This time spinning 10K RPM, we pressed our Dremel's abrasive element against one of the For those who prefer more ankle mobility while hiking, the low-top's lugs with 3.2N of force.

Our prediction was borne out as the tool wasn't able to bite into the hardy Vibram rubber over the course of the twenty-two-second test. Using a tire tread gauge, we found that we had only lopped off 0.3 mm of material from the lug. This is insignificant compared to the total amount of material underfoot and makes the For those who prefer more ankle mobility while hiking, the low-top much more durable than the average hiking boot. As such, we expect this boot to last dozens of hikes before wearing the outsole out completely.

Cushioning

Heel stack

Using our caliper, we measured the For those who prefer more ankle mobility while hiking, the low-top's stack to be 38.1 mm thick at the heel.

Merrell For those who prefer more ankle mobility while hiking, the low-top Heel stack

This is higher than our current lab average and means that we have plenty of foam underfoot to really luxuriate in the boot's plush midsole cushioning. This also elevates our heels and keeps us protected from underfoot hazards we encounter on the trails.

Midsole softness

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

Pressing our durometer against the midsole yields a positively plush reading of 18.6 HA. 

Merrell For those who prefer more ankle mobility while hiking, the low-top Midsole softness

This means that we enjoyed incredibly soft and luxurious landings no matter how rugged and harsh the terrains we traversed were. 

What's more, the midsole has a delicious rebound that puts a little spring in our step which, in conjunction with its feathery frame, makes the For those who prefer more ankle mobility while hiking, the low-top ride more like a trail runner than a boot. As a result, we frequently found ourselves tearing through the mile markers of our favorite trails swiftly and comfortably.

Difference in midsole softness in cold

We left the For those who prefer more ankle mobility while hiking, the low-top in the freezer for twenty minutes to simulate exposure to cold conditions. Taking another durometer reading of the midsole after that, we were so taken aback that we had to check that the freezer was running properly.

Merrell For those who prefer more ankle mobility while hiking, the low-top Pressing our durometer against the midsole yields a positively plush reading of 18.6 HA

The For those who prefer more ankle mobility while hiking, the low-top only becomes 4% firmer when exposed to cold conditions, giving us a still plush reading of 19.4 HA. This isn't only softer than the average boot under similar conditions, but at room temperature too. This incredibly consistent performance means that the For those who prefer more ankle mobility while hiking, the low-top should feel just as comfy and well-cushioned during frigid winter treks.

Stability

Lateral stability test

For a shoe with such a high stack of plush foam, we were surprised at just how well-planted we felt when shifting our weight from side to side in the shoe. 

That being said, we don't recommend schlepping a heavy pack over long distances in this shoe as sinking into that soft cushioning will require constant corrections for balance which will likely lead to foot fatigue and loss of stability over time. 

Torsional rigidity

The For those who prefer more ankle mobility while hiking, the low-top was quite difficult to bend and twist in our hands during our manual assessment, earning it a rather stiff 4 out of 5 on our subjective scale. This means that the shoe resists and mitigates any excessive lateral movements of our foot and maintains a relatively firm and stable base that helps to ensure steady landings.
