KEEN Targhee III Waterproof review

The Targhee III Waterproof is an iconic low-cut day hiker from KEEN that we recommend as a great choice for: 

• Casual hikers looking for a lightweight and comfortable shoe that can be used both for light hiking as well as everyday activities
• Those in need of supportive footwear with ample traction and bite in muddy and rocky environments
• Anyone in the market for a breathable waterproof shoe that will ensure a comfortable and dry hiking experience
• Hikers who frequently go on winter treks and need a shoe that performs consistently in cold conditions

Hikers with narrow feet will likely find themselves bumping against the walls of the Targhee III Waterproof, especially during descents. For a shoe with a more snug toebox, we suggest checking out the Hoka Anacapa Low GTX.

While the Targhee III Waterproof is relatively breathable for a waterproof shoe, it's going to feel quite stuffy during hot summer hikes. The Merrel Moab 3 is a more well-ventilated option that won't turn into a sweatbox as the mercury rises. 

If deep puddles and river crossings are part of the planned adventure route, we recommend opting for the shoe's mid-length cousin; the Targhee III Waterproof Mid instead.

We measured the Targhee III Waterproof's stack to be 29.5 mm thick at the heel which is right around the average range for hiking shoes. While this does include the shoe's chunky outsole and substantial insole, there is still plenty of foam underfoot to provide well-cushioned landings during our test hikes. 

Moving up to the forefoot, the Targhee III Waterproof's stack is shorter than average at 17 mm thick according to our caliper measurements. This gives us a good sense of the ground below for a natural and intuitive ride, while the midsole and outsole provide adequate cushioning and protection from any harsh objects below. 

The difference in our stack measurements leaves the Targhee III Waterproof with a drop height of 12.5 mm. This is slightly steeper than our current lab average but still feels quite natural while delivering a healthy balance of an elevated heel and a grounded forefoot. 

For more experienced runners who prefer a more parallel-to-the-ground experience, we recommend looking into the brand Altra and their wide range of zero-drop hiking and trail running shoes. 

The Targhee III Waterproof's midsole is rather firm, giving us a durometer reading of 31 HA.

This reading isn't out of the ordinary as hiking shoes tend to sport rather firm midsoles in order to promote a stable gait, especially when carrying a heavy load.

Nevertheless, we enjoyed well-dampened landings that felt forgiving and protective throughout our test hikes. No matter how harsh the terrain or arduous the journey, it was never foot pain that slowed us down. 

On the other hand, for those who prefer a more plush ride during their hikes, we recommend the Adidas Free Hiker 2 as a more suitable alternative. 

To test the effects of cold conditions on the midsole, we placed the Targhee III Waterproof in the freezer for twenty minutes. We then took another durometer reading of the midsole and were so shocked that we had to check that our freezer was running properly! While a reading of 34 HA puts it in the average range, the Targhee III Waterproof's midsole only becomes 9.7% more firm in the cold; thus making it much more consistent than the average hiking shoe. As such, the shoe's already firm ride won't feel too different whether out on the trails during summer or winter. 

The Targhee III Waterproof's insole is 6 mm thick according to our measurements, putting it on par with our current lab average. This insole provides excellent in-shoe comfort as well as arch support that kept us pushing through the mile markers. 

In addition to width, the shoe's toebox is also pretty tall (plenty of vertical space). With a height of 30.5 mm, it is among the tallest in our lab.

That's why we can't recommend the KEEN Targhee III WP to explorers with narrow feet. The Salomon X Ultra 360 would be a more appropriate option or this audience.

KEEN shoes have a good reputation for their rounded and extra spacious toeboxes. And now that we have a gel mould of the Targhee II WP, we can put its roominess into numbers.

The shoe's forefoot width proved to be on par with the average in the widest area of the forefoot. Our calliper showed a standard reading of 94.06 mm. But it's the front portion of the toebox that makes all the difference...

Measuring the Targhee III's width at the big toe mark, we got 74.57 mm which is a couple of millimetres wider than average.

Because it's narrower than the widest part of the forefoot by less than 20 mm, the shoe's toebox has a nice and rounded shape and is not very tapered.

In addition to width, the shoe's toebox is also pretty tall (plenty of vertical space). With a height of 30.5 mm, it is among the tallest in our lab.

That's why we can't recommend the KEEN Targhee III WP to explorers with narrow feet. The Salomon X Ultra 360 would be a more appropriate option or this audience.

Stability is the name of the game with the Targhee III Waterproof. We exuded confidence with every stride in this shoe whether scampering up and down hills for quick hikes or slogging our heavy supplies over long distances. Suffering a rolled ankle was the furthest thing from our minds while testing this incredibly stable shoe. 

Ordinarily, we'd expect a shoe this stable to be quite difficult to bend and twist in our hands. However, the Targhee III Waterproof only put up a moderate level of resistance to our manual manipulations, leading us to give it a middle-of-the-road 3 out of 5 for torsional rigidity based on our subjective assessment. 

This gives us a healthy balance of stability and comfort as the shoe conforms to the natural contortions of our foot to a certain extent while mitigating any excessive lateral movements. 

The rigid heel counter puts up more of a fight against our squeezing and prodding, earning it a stiffer-than-average score of 4 out of 5. This also helps to promote stability in our stride by locking our heel in place and limiting how far it can move laterally. 

The Targhee III Waterproof's midsole is about as wide as our current lab average at the forefoot, measuring 112 mm based on our caliper measurements. 

Back towards the heel, the Targhee III Waterproof's midsole is broader than average at 91.4 mm wide.

This gives us a good surface area of grippy lugs to prevent wobbly landings in this shoe. 

We secured the Targhee III Waterproof to our workbench and found that 29N of force is needed to bend the shoe 90 degrees, making it about as stiff as the average hiking boot.

This level of stiffness contributes to the shoe's stable and supportive underfoot sensation that keeps us feeling sure-footed even when schlepping a heavy pack. 

Further proving how winter-oriented this shoe is, we also repeated the fitness test after leaving the shoe in the freezer for twenty minutes. This seems to have had almost no effect on the shoe which only becomes 4.6% stiffer when exposed to the cold. This change is negligible compared to our current lab average and means that the shoe's ride will feel consistent all regardless of the surrounding temperature. 

As protective as all that rubber feels, it doesn't do the Targhee III Waterproof any favours in the weight department. At 17.1 oz (486g), it's significantly heavier than the average hiking shoe and puts the Targhee III Waterproof more on par with the average hiking boot. 

For a more lightweight option, consider the almost feathery Adidas Terrex Trailmaker instead. 

We don't expect much airflow from a waterproof shoe, though the Targhee III Waterproof surprised us during our smoke test with a slow but relatively steady stream of smoke making its way through the tongue. We wouldn't exactly describe it as airy, but the Targhee III Waterproof performs better than anticipated, earning a breathability score of 2 out of 5. As a result, the shoe will certainly feel quite toasty during warm hikes, but not nearly as bad as some of its other waterproof counterparts. Conversely, this makes the Targhee III Waterproof a great companion for those challenging and frigid wintertime adventures. 

Compare that to how easily the Merrel Moab 3 vents out the smoke, making it better suited for summertime hikes. 

The Targhee III Waterproof entirely blocks out the light when inspecting a backlit cross-section of its upper, confirming the shoe's insular and watertight nature. With the shoe being a low-top, however, we recommend avoiding splashing through streams as any water that does manage to get in through the top won't drain out. We recommend checking out the shoe's mid-length cousin, the Targhee III Waterproof Mid for treks where being submerged in water is a possibility. 

As we saw in the smoke test, the tongue is the only part of the shoe that promotes any airflow. To investigate this further, we looked at it under the microscope and found that the mesh is incredibly dense and compact enough to prevent water from seeping through.

First up to face the Dremel in our battery of durability tests is the Targhee III Waterproof's toebox. Spinning at 5K RPM, we pressed the tool's abrasive element against the shoe's reinforced toe bumper. 

After twelve seconds of grinding, our Dremel wasn't able to wear away enough material to reach the leather part of the upper, with only a barely noticeable scuff left in its wake. This confirms the shoe's tank-like build and means that our feet are well protected from any knocks or bumps along the way. 

Now focusing on another vulnerable part of the shoe, we set the Dremel against the Targhee III Waterproof's heel collar for four seconds. 

The damage is hard to assess visually, but there is a notable crater where the tool's abrasive element made contact with the shoe. The damage isn't too devastating however leading us to give the Targhee III Waterproof a heel padding durability score of 3 out of 5. 

Pressing our durometer against the outsole gives us a reading of 82.1 HC. This is on par with our current lab average and doesn't give us too much cause for concern regarding its durability. Our confidence in the outsole will be put to the test in the next section. 

Last to face the merciless Dremel is the outsole. Now spinning at a more formidable 10K RPM, we set the tool against one of the Targhee III Waterproof's lugs. 

After twenty seconds of debris misting our workstation, we assessed the damage with a tyre tread gauge and found that we had shorn off 1.1 mm of rubber from that lug. This is about the same amount that the average hiking shoe loses in the same test and less than 1/7th of the total rubber on the Targhee III Waterproof's outsole. It's going to take a lot of long and rugged treks to fully wear out this shoe. 

At 3.3 mm thick according to our caliper measurements, the Targhee III Waterproof's outsole is thicker than our current lab average. Having all this rubber underfoot gives us added confidence while traversing rocky or untamed trails. 

Using our calliper, we measured the Targhee III Waterproof's lugs to be 4.5 mm thick which is only slightly thicker than average. They have a solid bite to them that gives us confidence with every step while the multi-directional formation on the outsole did a good job gripping a variety of surfaces. Whether on dirt, mud, gravel, or grass, the Targhee III Waterproof never let us down during our tests out on the trails. 

The Targhee III Waterproof features a reflective pattern at the rear of the sho which partially runs up the finger loop at the heel. This is great for those occasions where we find ourselves hiking by the roadside at night. 

At 10.5 mm thick, the Targhee III Waterproof's tongue is slightly thicker than our current lab average. All that padding gives us an incredible in-shoe feeling that made us not want to take the shoe off after testing!  

As expected from a waterproof hiking shoe, the Targhee III Waterproof's tongue is fully gusseted on both sides. This keeps us safe not just from water entering the shoe, but any unwanted debris that might find its way in. 

The finger loop at the heel makes it a little easier to slide the Targhee III Waterproof on as well as adding a little stylistic flair to the shoe. 

Targhee III Waterproof's already supportive insole is easily removed if custom orthotics are required.
