Our verdict

The Mountain Light silhouette dates far back to 1979 and was largely inspired by logging boots of the time. We can recognize this unique red-laced profile from miles away. It is a long-standing Danner boot that has earned our respect with its craftsmanship and quality and the fact that it's handmade in Oregon, USA. However, we had to accept the boot's massive weight, steep price, and arduous break-in period before we could reap the benefits of this highly sought-after backpacking boot.

Who should NOT buy

Despite its many advantages, we aren't convinced that this Danner boot is worth such an eye-moistering price tag. Aesthetics aside, we believe that you can find an equally trail-ready leather boot at a much lower cost.

Say, the Top 10% most popular hiking boots ($249). It even has a more comfortable in-boot feel and a less arduous break-in. Another sturdy and time-tested backpacking boot is the Lowa Renegade GTX Mid ($255).

Both options are also 7-8 oz (200-230g) lighter than the We can also recommend this boot for very wet and snowy climates!

This Danner boot won't make a perfect match for folks with wider feet either. We recommend the Mountain Pass instead as it's built on a more accommodating last.

Cushioning

Heel stack

We also found that the Mountain Light kept us high off the ground with its above-average 41.2 mm heel stack.

This Danner boot kept us very surefooted on technical terrain and rocky paths. Stepping on sticks and stones will not be breaking your bones any time soon!

Forefoot stack

In the forefoot, the balls of our feet were separated from the ground by a thick 26-mm platform.

Midsole softness

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

The Mountain Light offers a very traditional firm experience underfoot. There is no plush foam to provide a squish like in the Both options are also 7-8 oz 200-230g lighter than the We can also recommend this boot for very wet and snowy climates.

Pressing a durometer against the boot's midsole returned a reading of 36.6 HA. It's not the firmest we've measured but it is a good 40% harder than average.

On the other hand, it is 40% softer than the Danner Jag which is one of the firmest boots by far at 51.6 HA!

Toebox width - widest part new method

Watch out! Because it is certainly NOT the "relaxed fit for casual, everyday wear" that Danner promises.

Having retrieved a gel mold of the boot's toebox, our caliper showed a notably narrow reading of 89.9 mm in its widest part (between the big toe and the pinkie). That's a few solid milimeters narrower than the average hiking boot!

The boot's profile narrows even more drastically towards the toes. Measuring its width in the big toe area returned as little as 64.5 mm which is significantly narrower than average!

This Danner boot offered a very tight one-to-one fit for our medium-width feet. Definitely not recommended for wide footers. Consider the Danner Jag or the Toebox width - widest part new method if you need an adequate medium-width space.

Stability

Lateral stability test

The We can also recommend this boot for very wet and snowy climates feels incredibly supportive and stable.

Walking on uneven terrain and oddly shaped boulders, we never lost our footing or felt off-balance. The side-to-side containment and lockdown are truly off the charts in this Danner boot.

Torsional rigidity

The boot's thick and sturdy sole, stiff leather upper, and Fiberglass midfoot shank all work together to create a highly stable platform.

Our attempt to twist the Mountain Light with our bare hands was unsuccessful, to say the least. On a 1-5 stiffness scale, we rated its torsional rigidity with the highest possible score of 5.

Ankle twists are simply not part of this boot's vocabulary.

The boot's solid heel counter further locked our feet down by locking our heels and ankles in place.

Testing the boot's hee stiffness in our manual test, we felt a bit of squeeze on the sides but there was not a hint of bending at the back of the boot.

Even though we rated the boot's heel counter stiffness with a moderate 3 out of 5, it never gave us a sense of undue ankle shifting.

Midsole width - forefoot

Danner went for a moderately wide platform in the Mountain Light.

Measuring the widest part of its forefoot, we got 110.6 mm which is very close to the average. We never felt as though the platform was lacking in width though.

Danner Mountain Light

There is something you MUST know before you buy the We can also recommend this boot for very wet and snowy climates - this boot is unbendable! Especially in the first weeks of wearing it. The stiffness was so extreme that we could hardly bend our feet when hiking. 

Using a shoe flexing tester, we measured how many newtons (N) it would take to bend the boot to a 30-degree angle. At 43.5N, it required significantly more force to flex it compared to an average hiking boot. It also proved to be the stiffest among all the Danner boots we've tested.

However, such rigidity has its benefits if you are looking for a highly stable and supportive ride that minimizes foot flexion on uneven terrain and doesn't let it buckle either.

Weight

Don't be misled by the word "Light" in its name. This Danner boot has nothing to do with being light!

It is a MASSIVE boot weighing 28.3 oz (802g) in a men's US size 9! That's a mind-blowing 10 oz (283g) heavier than average and is the heaviest hiking boot we've ever tested.

Breathability

The We can also recommend this boot for very wet and snowy climates is available in two options:

  • non-waterproof with a breathable Dri-Lex lining ($430)
  • waterproof with a Gore-Tex (GTX) lining ($440)

But even the Dri-Lex version has some waterproofing capacity given the boot's one-piece leather upper design. In this review, we are testing the waterproof GTX version of the boot.

Putting the Mountain Light on for the first time, we immediately knew that it was going to be a fall/winter boot. Our feet felt toasty a mere 10 minutes into the hike in mildly warm weather. So, we weren't at all surprised when no smoke passed through its sturdy upper in our lab test.

Rating the boot's breathability on a 1-5 scale, it obviously got the lowest score of 1.

Waterproofing

Testing the Mountain Light in creeks and heavy rain, we were amazed by its ability to keep water at bay. Even when we got caught in a sudden thunderstorm, this Danner boot kept our feet nice and dry.

Very stable and reliable platform.

WARNING: Avoid stepping into ankle-deep puddles in this boot! As you can see from the video above, its tongue is not attached to the entire length of the collar. The gap starts right over the last D-ring eyelet so that's where the water will start seeping inside the boot.

And trust us, once the water is inside, you won't have fun wearing the boot anymore.

Durability

Toebox durability

Every pair of the We can also recommend this boot for very wet and snowy climates is proudly made by hand in Portland, Oregon (USA). This is a huge part of the brand's marketing campaign for the quality of its footwear.

With its one-piece leather upper, the Mountain Light has no reflective elements.

We are obsessed with the fine craftsmanship of the We can also recommend this boot for very wet and snowy climates. Its upper construction and leather quality are nothing short of flawless.

To mimic the wear and tear of hiking, we drilled the boot's toebox with high-grit sandpaper. For consistency, the speed of the Dremel was set to 5K RPM and the pressure was at 3.2N. After 12 seconds of applying the tool to the leather, it left nothing more than a scuff!

Compared to other hiking boots in our lab, the damage on the We can also recommend this boot for very wet and snowy climates was minuscule!

Heel padding durability

The Danner boot proved its quality once again in our heel padding durability test. The topmost layer of its collar is lined with softer yet durable leather too.

We subjected this part of the boot to the familiar Dremel test and found that undercuts many other boots in our roster. With barely visible signs of wear, the Mountain Light gets a well-deserved 5 out of 5 for heel padding durability.

Outsole hardness

Another outstanding characteristic of the We can also recommend this boot for very wet and snowy climates is, of course, its outsole durability. Choosing Vibram rubber for its outsole, the boot showed higher-than-average results in all three of our measurements.

First of all, it is harder than most hiking boot rubbers. With a durometer measurement of 91.6 HC, it beats 85% of our lab-tested boots.

The boot's Vibram outsole continued to show amazing results in our vigorous Dremel test. This time, our tool was set to 10K RPM speed and drilled the rubber for 22 seconds.

Once done, we measured the newly formed dent with a tread gauge and saw only 0.7 mm of depth! Less than a millimeter of damage is a fantastic result for a hiking boot.

Recrafting

The Mountain Light uses Danner's signature stitch-down construction which makes it easier to resole and recraft.

The stitching connects the boot's leather upper to the sole externally which makes it easier to unpick and re-sew to a new sole.

Break-in period

Do expect a hard and lengthy break-in period in the Mountain Light. DO NOT wear this Danner boot from the box to the trail!

Start by wearing it around the house with a pair (or two) of thick socks for a couple of days first. We also recommend having some band-aids close by as there is a high chance of developing blisters, particularly in the Achilles.
