Tim Malacarnewrote a review of Millet Trident GTX Approach Shoe - Men's on February 17, 2018
Familiarity: I've put it through the wringer
Fit: Runs small
My use: I have used these for the past 9 months and put a few hundred miles on them. I've used them mostly for hiking on hilly and somewhat uneven (but relatively soft) forest trails with less frequent use on trails with rocky surfaces. Probably about half of those miles have come with a ~35lb pack.
Sizing: I find them to run slightly short. I do have my standard size (11.5), but my toes are touching the front of the toebox. I use them most frequently in the morning. When I wear them later in the day, they're almost too small. I recently ordered a second pair (non-GTX) half a size larger as these are sized well for scrambling but longer backpacking with extended downhills wouldn't be ideal. I do like the bluntness of the shape of the forefoot. They aren't wide, but they fit my somewhat straight across toes well.
Performance: I have loved these shoes. Previous to buying these, I was wearing trail runners/light hiking shoes and was getting pain from plantar fasciitis. I hike every day and increased pack weight over time, but once it got over 30lbs or so, my feet didn't like the trail runners, particularly on more uneven ground. I got these and the plantar fasciitis disappeared and hasn't returned.
These are simply a different class of shoe from a lot of running and hiking shoes. They're essentially low top boots. The stole is much stiffer than most other shoes and the Mulaz sole is more heavily lugged than the trail runner class of hiking shoe. They provide great foot support (which I find more important than ankle support) and great traction on loose surfaces to rock. The stiffness allows for precision when you're using the toes and edges on small holds, though you lose some sensitivity. They're pretty light for the burliness.
I have found them to be very comfortable in the heat for a Gore Tex shoe (though I'm interested to see if the non-Gore Tex version is even better). I have no complaints about the waterproofing.
I'm not tempted to break out into an impromptu trail run in these. They just don't feel like that kind of shoe. They're very much a low cut boot, which is exactly what I want when I'm carrying a pack on uneven ground.
The most comparable show i've tried is the Salewa Mountain Trainer low. I like the looks of the Mountain Trainer better and they appear to be very well made (though I have no complaints on the Millet). I couldn't get the fit to work for me though and I like the Millet's lacing system with the final eyelet being a speed lacing hook, so I sent those back in favor of a second pair of these and can't give a more in the field comparison.
