I really like Asolo Neutron boots. They are pretty reasonable price on Sierra Trading. They hold up really well and are very comfortable. Not my "go to" boots for climbing, but I'll use them for a quickie because I have them on every day. (I actually have 2 pair and switch back and forth - letting boots dry out between wearing them really extends the life - original pair is going on 3 years of every other day use). Also wore them backpacking down and up the Grand Canyon with no boot-related discomfort.
I have had several pair of Keen Targhee. Super comfortable boots (probably even more so than the Asolos). They are grippy in the tree and a little more flexible, but they just don't hold up. They cost 80% of what the Asolo costs, but last less than 1/4 of the time.
For climbing, I have Drayer Tango Light boots. They are great in the tree, but not all that comfortable on the ground. I change into them as I'm clipping into the rope and take them off pretty quick once I get down. Besides not wearing less comfortable boots walking around, I also have dry soles with no mud on them. They are more expensive, so this will make them last longer as well.
But this is all spikeless climbing, so I don't need a big heel on them. The Asolo or Drayer both hold spikes, but I wouldn't want to spend all day in them! I almost never use spikes...even on the few removals I do.
