I've put 13 miles on these so far in 4 runs, and they remain my least favorite shoes currently in rotation. However, I do keep them in rotation because I think they're valuable in enforcing good running form.
For context, my favorite shoes in rotation are my Brooks Launch GTS 8: light, stable, fairly well-cushioned. The Enda Koobi Foras, in contrast, feel heavy (though the numbers don't look bad), with limited stability and cushioning. A run in the Koobi Foras always feels longer than a run in any of my other shoes because my body has to work so much harder to stay stable and absorb shock.
And that's where I see the value in keeping them in rotation. I've found that I can still enjoy the run, as long as I maintain good form. If I start overstriding or slouching or something, things quickly start getting uncomfortable, and that's a good incentive to fix my form. I don't know if I'll ever use these for long or fast runs, but I'll probably keep taking them on short runs at an easy pace just for that running form discipline.
Regarding other complaints I've seen about these: They do start out uncomfortably narrow around the forefoot, but I found that this issue simply disappeared on my second run. I've found that the short tongue isn't an issue if I use a runner's knot. They DO run warm, to the point where it gets uncomfortable at air temperatures of 80F or above. To me, that's fine, since I bought them with the idea that they might be good for winter running here in Minnesota.
They have really good traction on the dirt paths and asphalt roads I've been using them on. I have no idea how they do on sand, gravel, and rocks.
In short, if these had been available at my local running store, I would never have bought them because they're not what I look for in a running shoe. If you want trail shoes that feel almost minimalist while still protecting your feet, though, these might be for you.
