I own 12 pairs of FiveFingers and the KSO EVO is definitely the most true version of the barefoot minimal experience. Pretty sure this is the thinnest sole Vibram makes on the FiveFingers so you're going to really get that true ground feel out of this pair. You'll basically feel like you're actually barefoot. It's a great shoe to wear in the gym or for use on concrete and pavement. I mistakenly took them on a short hike last week and I would suggest you don't take them off road as I could really feel every pebble, stick, and stone I stepped on and it was really uncomfortable. I own the V-Trail too and that option is what I should have worn on that type of terrain...but you live you learn!
