I'd been eyeing a new pair of mid hikers after my old boots finally gave up the ghost on a soggy fall loop around Mount Hood. The trail was classic Oregon: roots, mud, standing water in every low spot. My previous boots had developed a slow leak months earlier that I'd been pretending wasn't there, and by mile six my left sock was a sponge. That's the kind of humbling moment that makes you actually sit down and research your next purchase instead of just grabbing whatever's on sale. When I came across the KEEN Men's Zionic Nxt Mid, the waterproof promise and the ripstop build caught my attention. I ordered a pair and took them out to see if they'd hold up.

What I noticed first
Out of the box, the Dark Olive/Black colorway is sharp without being loud. These look like a boot that means business, not a boot trying to cosplay as a trail runner. The ripstop mesh construction is the first thing I touched, and it feels noticeably different from standard nylon uppers. There's a stiffness to the reinforced overlay zones, especially around the toe box and lower ankle, which gave me confidence that the material won't abrade through on rocky scrambles.
The lacing system uses speed hooks on the upper section, and getting a snug, even lace tension was quick. KEEN also uses 100% recycled plastic laces, which is a small detail I appreciated. The cushion panel near the Achilles is easy to notice when you slip your heel in. I've wrecked my fair share of Achilles tendons on long descents, so anything that reduces hotspot pressure there gets my attention immediately.
One thing I'll flag right away: the toe box runs on the roomier side, which KEEN calls their Contoured Fit. If you're used to a snug, performance-running-shoe feel, there's an adjustment period. For me, after a knee injury forced me to slow down and actually pay attention to foot comfort on long days, the extra room was welcome. But if you've got narrow feet, I'd say size down half a step and see how that sits. Check sizing options on Amazon before you order.
What I actually liked
The KEEN.DRY waterproof membrane is the headline feature, and honestly, it delivered on the trails I tested it on. I hit a stretch of the Larch Mountain trail on a drizzly weekend where the path was basically a shallow creek for about a quarter mile. Boots in, no hesitation. My feet stayed dry. The membrane breathes well enough that I didn't feel like I was hiking in plastic bags, though I'll be realistic: no waterproof boot breathes like a non-waterproof boot. On a warm day with sustained climbing, expect some heat buildup.
The KEEN.ALL-TERRAIN rubber outsole with 4mm multi-directional lugs gave me solid grip on wet root networks and muddy switchbacks, which is exactly the test case I care about most in the PNW. The lugs bit into soft ground without packing up with mud, and on wet rock they performed reasonably well. Not crampon territory, but I didn't feel sketchy on anything a day hiker would realistically encounter.
The full-length plate underneath is a feature I didn't fully appreciate until mile eight of a loaded day pack outing. On rocky, uneven ground, that underfoot support reduces the micro-adjustments your foot and ankle have to make constantly, which translates to less fatigue. Combined with the high-rebound foam cushioning, the platform feels lively rather than dead, which matters on long descents when your knees are already doing a lot of work. You can grab these on Amazon here.
The removable footbed is a practical bonus. I've swapped in my own aftermarket insoles in other boots, and it's always a fight with a glued-in factory bed. KEEN made it easy, which I respect.
My one real criticism: the upper breaks in a little slowly. The first two outings, I had minor rubbing at the ankle collar. Nothing that drew blood, but enough that I was reaching for my blister kit. By outing three it had softened up, but if you're buying these for a big trip that starts in two weeks, do yourself a favor and wear them around the house and on shorter walks first. Don't learn this the way I learn most things.
Compared to what I'd used before
My previous daily driver was a mid boot from a competing brand in a similar price bracket. I won't name it, partly because they're a fine company and partly because my pair had been through more than it deserved. The biggest difference I noticed switching to the Zionic Nxt Mid was the weight-to-support ratio. The Zionic Nxt feels nimble for a mid-height waterproof boot, something I'd describe as closer to a trail runner in stride feel than a traditional leather hiker.
The outsole grip on wet rock is roughly comparable to what I'd gotten used to, maybe a slight edge to the Zionic Nxt on muddy terrain thanks to the lug geometry. The breathability is similar, which means: pretty good for a waterproof boot, not magical. Anyone coming from a non-waterproof trail runner will notice the difference on hot days.
What the Zionic Nxt does better is the ankle collar cushioning and the Achilles relief panel. My old boots had a hard collar edge that I'd taped over on every multi-day trip. That's not a problem I've had with these. If you're shopping for a mid waterproof hiker on Amazon, these are worth a serious look.
| Pros | Cons |
|---|---|
| KEEN.DRY membrane kept feet dry on wet PNW trails | Ankle collar takes 2-3 outings to break in fully |
| 4mm multi-directional lugs grip mud and wet roots well | Roomier toe box won't suit narrow-footed hikers |
| Full-length plate reduces foot fatigue on rocky terrain | Breathability is decent but not exceptional on warm climbs |
| Achilles cushion panel noticeably reduces hotspot pressure | Price not listed on Amazon PA-API; check current pricing before buying |
| Removable footbed makes aftermarket insole swaps easy | Lug pattern packs with mud in very saturated clay soil |
| Recycled plastic laces and consciously made materials |
If you're a PNW hiker who spends most of their time on wet trail and wants a mid boot that doesn't feel like a brick, the Zionic Nxt Mid is a genuinely solid option. Break them in before your big trip, account for the roomy toe box if you're narrow-footed, and you're getting a waterproof, well-supported hiker that won't quit on you in the rain. I'll keep reaching for mine on the kind of damp, unpredictable days that Portland specializes in. Happy trails out there., Dave
