Very good!!! They fit comfortably and softly as they should. I ran (2023) Zagori at 21k and their performance on the quite technical route was fantastic. They didn't tire me, didn't give me blisters, didn't slip anywhere, very strong grip on the ground. Of course, all of this on dry ground, I haven't run them yet on mud and slippery leaves, we'll see!
I also have Saucony Peregrine but those are for more "wild" short routes, for example Vertical (for 3-5 kilometers), while the Merrel ones are for longer distances where you want more comfort. I was impressed that they didn't hurt me even on technical descents!
