I have a set of 800gm Danner GTX leather's that I love and are bomb proof. They're very flexible and warm, but heavy and only for winter use.
I wore out a set of Montrail trail runners, don't know the model as the tag had long since worn off. By FAR the most comfortable set I have ever worn and sticky like glue. Too bad the new ones don't hold a candle by comparison.
I also just wore out a set of Vasque Velocity trail runners, comfortable and very grippy, to the point I don't want to retire them despite not having any tread left. The only issue is they had no midsole tread making rock hopping and/or trail running downhill treacherous. The foam also compressed way too fast.
I have tried Merrell Phaser Peak, Helium Ventilators, Pulse, and Yukon shoes and while all are very comfortable, the grip sucks and is downright treacherous on wet rock. On the dry they're fine, but otherwise I leave them for work around the farmhouse. They fit very well though and the Yukons have many miles and 8 years on them flawlessly. I leave them for light winter hiking now.
I tried a set of Salomon XA GTX shoes and loved the fit, but they fell apart in about 6 months so I returned them. I have heard their quality was lacking and was reserved about buying them, so I wasn't surprised when they started letting go.
The Merrell Radius Kangaroo/BOA's seem to be grippier, so I'm trying them out now. I have not had them on wet rock yet, so time will tell. Very comfortable though.
I picked up some Garmont Eclipse 3 XCR shoes and like them so far, but they don't fit as well as the Montrails or Vasques, and are too hot for summer hiking. They do seem grippy though.
Most of my shoes have the yellow vibram soles, but they differ in terms of grip when it's wet.
I typically use trail runners over a standard mid or heavy backpacking boot as I find them more comfortable. I've resigned myself to just buying a new set every year. It's too bad they change them so often, just when I get used to a set I like, they're gone from the lineup.
Most of the new ones I've tried on I don't care for, but I can be particular about my shoes. I would rather replace them often and not slide down mountains than have them last longer, but that's just me.
