There is a huge variation in how different Vibram soles interact with rock, ranging from quite grippy to slick as snot.
If good traction on rock combined with good ankle support in a very hiking friendly boot is what you are after, the La Sportiva Trango Cube is the best I've used, and I've used a lot of different mountain boots over the years. They even started making this boot in a Kryptek pattern after figuring out that it had become quite popular with mountain hunters.
The La Sportiva last (fit) isn't for everyone. Based on what you've described, the category of boot you should be looking at is an alpine climbing, mountaineering style boot meant for mixed terrain, that is rock, trail, and snow. These boots will, generally speaking, be stiff enough to handle steep ups, downs and side-hilling, with enough rocker in the sole to hike well, and have a soft enough rubber on the sole that they grip rock well.
The "durometer" of a given rubber will affect how it interact with surfaces such as rock. A lower durometer (softer) rubber will be more grippy, but wear more quickly. A higher durometer (harder) rubber will be less grippy on rock and other surfaces, but will last longer. As was mentioned above, all high end mountain boots can be resoled, usually a few times, before the uppers wear out.
Here is an article on the topic of footwear for mountain hunting where some of these things are discussed and more are discussed.
If there is a more commonly debated and frequently agonized category of equipment in the realm of mountain hunting I don’t know what it is. In every pre-trip planning process, ...
