July 21, 2025Every product I review has been tested—on trips, on the trail, or in everyday life. Whether I’m camping in the Northwoods of Wisconsin, biking in Arkansas, or getting outside close to home, I only share gear I use. I look for well-made products built with purpose. My decisions aren’t based on what’s cheapest or trendiest—they’re rooted in craftsmanship and brand story. I’m reviewing it because I use it. That’s the only reason it’s here.
Why I Chose the Saentis TR Low GTX
I’m already a big Mammut fan—but mostly for their ski and alpine gear. Trail running shoes weren’t what I associated with the brand. But they had a sale, and I needed a new pair of trail shoes to get back to dirt miles instead of pavement.
I tried two versions: the Saentis TR Low and the Saentis TR Low GTX. I started with the cheaper non-GTX version, but it didn’t feel quite right. So I swapped it out for the GTX version, and I’m glad I did.
Where I Tested Them: Rock Cut State Park
One of my go-to places close to home is Rock Cut State Park—it’s where I ride mountain bikes, and now, where I trail run too.
I took the Saentis TR Low GTX out for a first run on RC Classic, a two-mile loop full of roots, short climbs, and uneven terrain. I didn’t know what to expect, but these shoes felt great right away—light, snug, and agile.
They handled root-heavy sections and rocky inclines easily, and I liked the added protection of the rubber toe cap.

Lightweight and Fast-Feeling
This is Mammut’s lightest waterproof trail runner—and you feel it. They almost disappear on your feet.
Waterproof but Breathable
GTX protection means you can run through puddles or wet grass without thinking about it.
Snug, Secure Fit
They wrap your feet like a second skin. It’s part of why they felt so fast and natural, almost like barefoot running, but without the pain.
Great Trail Grip
Rooty singletrack? No problem. The outsole traction and low profile gave me a confident, stable feel even on uneven ground.

Honestly, not much. They don’t feel plush or cushioned like some max-stack shoes, but if you like to feel the trail, that’s a good thing.
If you’re new to trail running or used to bulkier shoes, they might feel minimal at first. But once you get moving, you’ll appreciate it.
Best Place to Buy the Mammut Saentis TR Low GTX
You can purchase the Alpha Breeze Tent directly from Snow Peak or through a trusted retailer, such as REI. Prices are the same at both.
Final Take
The Mammut Saentis TR Low GTX is the trail running shoe I keep reaching for. It’s lightweight, waterproof, snug in all the right ways, and built to move fast across uneven terrain.
If you're looking for a low-profile shoe that still offers protection and grip, this one’s a great choice—especially if you already trust Mammut for outdoor gear, like I do.
