The Mammut Aenergy Hike Low is a new hiking shoe for 2025. Its technical specs look great on paper—and it comes in some sick colorways—but how does it perform in the field? To answer this question, I scored a pair to test and review in New Mexico's Sangre de Cristo and Sandia Mountains. Over the past month, I've put my pair through some test hikes that I handpicked to evaluate this shoe's support, weight, fit, comfort, weather protection, traction, and overall value. My Mammut Aenergy Hike review gives you the goods based on my first-hand experience and my professional experience working in the outdoor gear industry.

Mammut Aenergy Hike Low Review
I tested and reviewed the Mammut Aenergy Hike in the summer of 2025. For my test hikes, I chose an easy trail (4-mile loop on the Sandia Crest trail), two moderate trails in Embudito Canyon (each approximately 5 miles with 1500 ft elevation gain), and a difficult day hike in the Pecos Wilderness (14 miles, 3000+ elevation gain). Testing hiking shoes over a range of trails and varied terrain helps me pinpoint each shoe's best use and its specific pros and cons.
My Mammut Aenergy Hike review is based on the non-waterproof, low-cut version (since I live in the high desert). Mammut also makes a GTX (GORE-TEX) waterproof version, a burlier Aenergy Mtn (Mountain) version, and a taller mid-cut version. My nephews think my powder blue and white pair looks sick, but I prefer Mammut's other colorways—from the muted Strata-Black to eye-popping Black-Mammut Red or Marine-Dark Glacier Blue.
It turns out these shoes aren't only good-looking. They're pretty solid in the field, too. Here's my in-depth, first-person take on the Mammut Aenergy Hike:
Testing the Mammut Aenergy Hike in New Mexico's Pecos Wilderness
Support
The Mammut Aenergy Hike is surprisingly supportive for such a lightweight shoe. It's stiff from the heel to my foot's natural flex point, where there's a little bend right where there should be. The thick, max cushion midsoles—35mm of cush under the heel and 28 under the toes—not only adds comfort but also foot support and torsional rigidity. My feet especially felt this support on my 14-mile hike to Lake Katherine in the Pecos Wilderness.
The arch support on this shoe is especially pronouced. Mammut doesn't call this a stability shoe, but it sure feels like one?! There's clearly extra structure and firmer foam along the inner midfoot area. Especially if you over-pronote, that could be welcome support. However, I'm a supinator, so that firm, medial structure seemed to put more pressure on my outer ankle, especially my downhill ankle on steep side-hill trails.
Overall, this moderately stiff yet well-cushioned hiking shoe delivers above average support—in spite of its below average weight.
The Mammut Aenergy Low weighs less than 2 lbs per pair
Weight
These days, brands will call almost every hiking shoe "lightweight"—no matter what it weighs. In this case, though, the Mammut Aenergy Low really IS a lightweight hiking shoe. Even in a men's size 13, my pair weighs less than two pounds. It's one of the lighter hiking shoes I've tested and a good 5 ounces lighter than the average hiking shoe in my size.
If you're looking for a lightweight hiking shoe, the Mammut Aenergy should be on your radar. Its weight is especially impressive when you consider how much support and cushioning Mammut packed into it.
Mammut shoes don't run as narrow as most European brands
Fit
Mammut doesn't seem to run as narrow as most European brands (which is why some European customer reviews find it runs large). However, I needed to size up extra to get a good fit for my wider feet. My everyday shoe size is a 11.5 US, and both the Mammut Aenergy and Mammut Sertig II fit me well in a size 13. Hikers with more standard-sized feet should be fine sizing up a more typical 1/2 size to full size for hiking.

Comfort
Most hikers will find something to like about the Mammut Aenergy Hike, but it may not work for supinators or flat-footed hikers (like me). In my case, this shoe's aggressive arch support pushed too hard against my flat feet, and its stability features put plenty of pressure on my outer ankles. Luckily, most of you have healthier lower bodies than me, so you probably won't have the same issues.
Based on my test hikes, I'm confident that most hikers will find this a comfortable hiking shoe. I can count on one hand the number of hiking shoes or trail running shoes that are highly supportive AND highly cushioned AND legitimately lightweight. The Mammut Anergy is one of them.
If you're looking for significant foot support and lateral stability, this shoe has it. Do you prefer more cushioning? The Aenergy rivals the best Hokas for hikers and offers more cushioning than Salomon's stable yet agile trail shoes. Do you prefer lightweight hiking shoes? This is one of the lighter ones I've tested and reviewed.
If this shoe fits you—and you appreciate stability and arch support—you'll probably find it comfortable. Maybe super-comfortable.

Weather Protection
Mammut didn't skip on waterproofing, using a GORE-TEX membrane in the Aenergy Hike GTX. (Pro tip: "GTX" stands for GORE-TEX in outdoor gear and apparel.) In spite of what many bloggers claim, GORE is breathable and reliably waterproof. So this is another plus.
However, my review focused on the non-waterproof Aenergy Hike since waterproof footwear is usually unnecessary and undesirable in the desert. My non-waterproof pair did wear cooler than my waterproof hiking shoes, which was clear on my 14-mile hike to Katherine Lake. If you mostly hike in hot and dry environments, you can also save $20 by choosing the non-GTX Aenergy Hike Low over the waterproof Aenergy Hike Low GTX.
The Aenergy Hike demonstrated solid traction on mixed terrain
Traction
The Aenergy Hike provided reliable traction on my test hikes. My test hikes spanned almost any surface you'll encounter—rock, sand, gravel, scree, talus, dirt, and mud. Outside of some harmless slips on the steep weathered granite section of the Embudito Trail, I had no traction troubles.
The tread on this shoe is best for mixed terrain. It's moderately deep lugs are moderately large and widely spaced, balancing rock traction with traction for soft and loose sediment. If you mostly hike muddy trails or steep and loose stuff, you might want a hiking shoe with more aggressive 5mm lugs and a heel brake (which the Aenergy does not have). Likewise, if you mostly hike solid rock, you might want softer, more climb-oriented rubber rubber. For most hikers, however, this shoe's moderate tread should fit the bill.

Value
With hiking shoe prices sky rocketing the past few years, the Mammut Aenergy is more affordable than I expected. My non-waterproof pair now retails for $149, and the GORE-TEX option goes for $169. Believe it not, that's now a better than average price for the best hiking shoes. It costs less than its closest comps, the HOKA Anacapa Breeze ($155) and Anacapa 2 Low GTX ($180).

Mammut Aenergy Hike: Pros & Cons
The Aenergy Hike Low got through my review with several clear strengths and few red flags for hikers with lower body issues. Here's a quick overview of the shoe's pros and cons:
Should you buy the Mammut Aenergy Hike Low?
The Mammut Aenergy stands out for balancing support, cushioning, and stability with weight savings and agility. It's a high-performance hiking shoe for fast hikers with light packs and potentially a match for hikers with high arches, max cushion fans, and day hikers who want a lot of cushioning and foot support to take some heat off their feet. This lightweight hiking shoe seemingly has something for everybody. However, its mid-foot support and stability features may be uncomfortable for hikers with flat feet and supinators whose ankles roll outwards. Outside of those concerns—which are limited to a small number of hikers with foot and ankle issues—this shoe really impressed me. Usually, hikers need to choose between shoes that are either supportive or lightweight, stiff or cushy. Somehow, the Mammut Aenergy is all of the above, which should appeal to a wide range of hikers.
Conclusion
As an outdoor industry pro, I normally think of Mammut as a leading brand for climbing ropes, avalanche safety equipment, and mountaineering gear—not footwear. But I've now tested and reviewed two Mammut trail shoes, and both of those impressed me. Based on my field testing, I'll be adding the Mammut Aenergy Hike to my list of the best lightweight hiking shoes.
That being said, we all have different feet and different hiking styles. If you're not sold on the Mammut Aenergy hiking shoe, please check out my review of the Mammut Sertig II trail running shoe, my other hiking shoe reviews, and my curated list of the top 10 hiking shoes for men and women.
