Our Take:
4.3/5

The Keen Targhee Apex Waterproof Mid ($190) is an intriguing chimera of a hiking boot. It’s one of the lightest mid-cut boots we’ve tested thus far, and its design—which pretty much fuses a high cuff onto the lower, hiking-shoe version of the Targhee Apex—works in some ways, but not in others. The cuff itself seems like an afterthought, but otherwise this boot delivers an attractive combination of comfort and protection for hikers who prefer light and flexible footwear.

Pros

Super light for a hiking boot, which promotes speed and helps stave off fatigue.
Midsole wrap and rubber toe bumper provide a good amount of protection.
Wide toe box works well for hikers who might struggle with narrow footwear.

Cons

Outsole cutout that exposes midsole foam could cause durability issues.
Relatively flimsy cuff construction does more for defense than stability.
Bland insole design doesn’t provide a lot of arch support, and you should replace it.

Foot feel is one of the Keen Targhee Apex Waterproof Mid’s biggest strengths, and I noticed it as soon as I left the trailhead for my first testing hike, a 7-miler on Washington’s Whidbey Island. After dealing with foot issues for more than a year, I’ve become especially picky about the shoes and boots I hike in, and this one stood out right away for its generous toe box. My toes had plenty of room to spread naturally without sliding around, and the heel cup maintained a solid hold on the back of my foot throughout testing.


Underfoot, the Keen Targhe Apex Mid lands somewhere between a flexy hiking shoe and a more traditional boot. The outsole bends slightly but still maintains enough structure to feel supportive on uneven ground, and the midsole cushioning is soft without feeling overly squishy—it’s less plush than something like a Hoka boot but still forgiving enough to smooth out rough trail surfaces. The padded cuff adds a comfortable buffer around the ankle, though the tongue is thin.

Including the Whidbey Island hike, my first two testing outings in the Targhee Apex Mid were on muddy, rocky trails, where classic Pacific Northwest coastal winter conditions resulted in slick and uneven terrain. The hikes totaled about 10 miles and 2,000 feet of gain, and this boot felt comfortable the entire time; I never developed hot spots or pressure points. My only real complaint is that the stock insole feels flat, which limits arch support. After swapping in aftermarket insoles, the overall comfort improved significantly.

For such a lightweight hiking boot, the Targhee Apex Mid provides a good amount of support, if not quite the weight-bearing heroics of heavier hiking boots, such as Danner Mountain 600 Leaf or the Salomon Quest 5. The cuff reaches just above the ankle, offering more coverage than a low-cut shoe but not a ton of stability—the natural stride it promotes is nice, but you can definitely still roll an ankle. The lacing system includes traditional eyelets along the midfoot and a hook near the top of the cuff, which helps cinch the upper portion down tightly. That setup helps stabilize the foot without creating pressure points and is aided by a shank, as well as a structured portion of the midsole that rises around the middle of foot, granting a boost to lateral stability.


The Targhee Apex won’t feel as secure as a heavy backpacking boot, but it performs well within its intended use, which is day hikes and light-to-moderate backpacking trips. During an overnight hike to Steliko Lookout in Washington’s Central Cascades, I wore this boot while carrying around 30 pounds of gear. Despite the relatively flexible ankle structure, the Targhee Apex handled the weight well on a trail that included dirt, mud, and rocky sections. I never felt unstable or worried about injury, thanks to the supportive platform underfoot. Backpackers who routinely shoulder heavier loads might want a sturdier boot, though.

The Targhee Apex Mid uses Keen’s proprietary Keen.All-Terrain rubber outsole, paired with medium-height lugs that are spaced fairly widely. The lug pattern varies, with different shapes and orientations at the front and rear of the boot to help generate grip in multiple directions. The rubber compound itself is quite firm rather than sticky, which differentiates it from some of the category's top outsoles, such as Vibram Megagrip.


On the trail, the boot’s traction proved reliable across a range of conditions. While hiking down muddy trails on Whidbey Island, the Keen Targhee Apex Mid maintained a solid grip on slick soil and roots. I also scrambled around wet coastal rocks during testing and was pleasantly surprised by how confidently the outsole held on to damp surfaces. Having said that, I don’t think the outsole would be able to match Megagrip or La Sportiva’s Frixion compound if you were to take it into steep, loose, rocky terrain. That’s the only thing keeping it from achieving a perfect score in this metric, but all in all the traction feels very dependable and predictable.

The Keen Targhee Apex Waterproof Mid feels thoughtfully built and well-constructed, with particular credit to its synthetic upper. The upper’s thick mesh and TPU overlays give the boot a largely seamless appearance, with very little exposed stitching, and it doesn’t seem like it will puncture easily. The toe cap also deserves a mention; it consists of a thick rubber bumper that wraps well over the front of the shoe and protects the toes from impacts with rocks and roots, as well as wear and tear in areas that can scrape the ground hard if you’re not careful. After roughly 20 miles of use—including hikes on rocky trails, squelching through muddy terrain, and city walking—the boot shows no signs of meaningful wear. That said, the true test of longevity comes as the miles really stack up, and we’ll follow up if any issues arise.


As it stands, I’m wary of the exposed midsole foam in the outsole cutout on the bottom of the boot. I’ve had poor results with Hokas that also have exposed foam on the outsole, and even though the Targhee Apex’s material feels more dense than that of midsoles that have caused me trouble, it raises a question mark. If it becomes an issue as I hike more in this boot, I’ll update this review. The Targhee still feels like a good value at $190, though, especially when you take into consideration the prices of similarly lightweight, high-performing hiking boots, which often run north of $200.

Protection is another area where the Keen Targhee Apex Mid outpunches its weight class. The rubber toe bumper wraps high over the front of the boot and provides solid coverage against impacts. I never felt any pain after accidentally smoking a rock with my toes. Underfoot protection is also strong. The combination of the firm outsole, cushioned midsole, and shank isolates your feet from sharp terrain. Even on rocky ground, I never felt uncomfortable pressure points on the sole of my foot, which helps make this boot well suited for longer hikes.


There’s a decent amount of armor along the rest of the boot as well. The midfoot features slightly thinner material than the toe cap, but the foam and overlays still offer a respectable buffer against trail hazards. At the back, the structure becomes even more rigid, with a thick heel counter that helps stabilize the foot and guard against accidentally intense heel strikes. The Targhee Apex Mid clearly isn’t as impenetrable as a big leather boot like Keen’s own Targhee IV, but it holds its own.

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.

Coming in at 1 pound, 6.2 ounces per pair of the women’s version, the Targhee Apex Mid is fantastically light for a full-coverage hiking boot. On the trail, it feels much closer to a more minimalist hiking shoe than traditional mid-cut footwear, which makes it easy to move quickly and comfortably across long distances. I never felt the usual urge to take them off immediately at the trailhead, and for hikers who prefer light and responsive footwear but also want ankle coverage, this boot provides just that.

Waterproof Liner
The Targhee Apex Mid uses Keen’s proprietary Keen.Dry waterproof membrane combined with a PFAS-free durable water-repellent treatment on the upper. During my testing on muddy and puddle-filled trails, the boot kept my feet completely dry. The terrain around Whidbey Island is often saturated during winter months, but water never penetrated the membrane.


Breathability was also surprisingly good considering the waterproof build. Temperatures during testing stayed below about 50 degrees, but the Targhee never felt overly warm or damp inside. The tongue area appears to be the most breathable section of the upper, while the rest of the shoe focuses more on weather protection.

I normally wear a women’s size 10 in street shoes and a 10.5 in hiking boots, which is the size I tested for the Keen Targhee Apex Mid. The fit felt true to size, with a roomy forefoot and slightly narrower midfoot that helps keep the foot locked in place.


The wider toe box is particularly welcome for hikers who struggle with feeling cramped in their footwear. My toes had plenty of space to move without developing blisters or pressure points, and the heel remained secure once the boots were fully laced. Frustratingly, though, Keen does not sell an even wider women’s version of the Targhee Apex Mid, as it does with the men’s model.

Altra Lone Peak Hiker 3 ($160): Go Comfier…
The Lone Peak Hiker 3 is only a couple ounces heavier than the Targhee Apex Mid, weighing 1 pound, 8 ounces for a women’s pair. It can’t compete with the Targhee Apex when it comes to protection and precision (it has a thin suede upper, and we found its forefoot to be a bit too roomy for technical hiking), and we wouldn’t trust its more minimalist midsole with schlepping the kind of weight we carried in the latter boot. But where the Lone Peak Hiker stands out is its extremely accommodating feel, which we’ve compared to a slipper. That spacious toe box feels luxurious, as does the close-to-the-ground feel and zero-drop design. Saving some money doesn’t hurt, either, but the Targhee Apex is the more well-rounded boot. For more, read our review of the Lone Peak Hiker 3.


Keen Targhee IV Waterproof ($180): …Or Burlier
The OG Targhee may have been bypassed design-wise by the Targhee Apex and its lightweight ilk, but there’s still something to be said for brawny leather hiking boots. That conversation mostly revolves around durability and foot protection, both of which you’ll get a ton of with this boot. However, the Targhee IV is stiff and requires break-in time, weighs almost twice as much as the Targhee Apex, and actually provides a little less support than we’d like for a boot this beefy. We also found its traction unimpressive, and for the cost, you’re betting off getting the lighter, newer boot unless you spend all your time hiking in extremely rugged terrain. To learn more, check out our Targhee IV Waterproof review.

4.3/5

The Targhee Apex Waterproof Mid is one of the lightest hiking boots we’ve tested, which is a feat unto itself. But it’s much more than a novelty, with a versatile design that hits many of the marks we look for in mid-cut boots. We have durability concerns, though, and its low cuff didn’t exactly win us over.

With a roomy toe box, zero drop, and soft suede upper, the Lone Peak Hiker 2 is the slipper of hiking boots. It’s undeniably comfortable, but most hikers will find that it doesn’t offer enough protection or support for anything more than smooth trails.

Keen Targhee IV Mid Waterproof ($180)

A beefy, traditional hiking boot, the Targhee has been around for twenty years and is still here to tell the story. However, it’s becoming long in the tooth compared to more modern designs, with a clunky build and particularly middling traction. It excels in durability and protection.

Is the Targhee Apex Mid for You?

The Keen Targhee Apex Waterproof Mid makes a lot of sense for hikers who want to reap the benefits of both light trail shoes and burly, mid-cut boots, without fully committing to one or the other. Its wide toe box, comfortable ride, and decent support made it particularly appealing for day hikes and reasonable backpacking routes. While it may not be the best pick for intense routefinding in steep terrain, it still has plenty of stability and traction for the majority of hikers.
