"Really good approach shoe with limited durability"
First, I love this shoe. No need for other shoes below the snow line if you have good ankle support. The Vibram grip is insane, way more than you are used to with normal hiking boots, since this shoe flexes more and gives you more surface area. It's really comfortable too. I used this shoe for two month of intense hiking, scrambling, and even rock climbing. Only drawback, after all this abuse it is pretty much worn out and falling apart. The durability could be a little bit better!
I had these shoes and they were not right for me. I have a wider foot and they were not comfortable on the sides. The tongues seem to keep sliding to the side and this is something ive heard from other people with the same shoe. I had to return but they could be perfect for you.
