I've had my MT 10's for a while now and have definitely enjoyed them. I have never worn socks in them either and they are super comfy shoes. I do have a few gripes about them though:
-They stink once they get wet. I mean they really really stink. The entire car reeks from the ride home and they have to live outside.
-The inner liner has gotten a bit funky. It's kind of bunching up in some places and almost feels like it's separating in places.
That being said I really really love these shoes. Even with the 4mm heel to toe drop it's barely noticeable. They really don't feel that much different from a pair of Merrel Trail Gloves I have and I think they're zero drop. The rubber also seems to be pretty sticky when boulder hoppin'.
I've run on soft trails, golf courses, technical trails up in Montana, and recently did a 9 mile hike here in Southern Arizona. Again other than the smell and potential durability issues these have been one of my favorite shoes to run and hike in for a while now.
Hope this helps a little!
