I just wear higher socks and I've had no problems with the collar on the LunarEpics.
If the soles comfort is your main concern though, LunarEpics comes in lows and if you want a cheaper non-FK version, LunarGlide8s are also a good option.
Zoom All Outs best for running though if you want more reponse and that snap back to propel you forward. The zoom being cut off by the toe feels weird initially though. They should have done the same as the KD9s where it just extends all the way to the toe.
I wouldn't wear no-shows anyways w/ the LunarEpics, but that's good to hear. Just have been hearing horror stories about the shoe even rubbing though socks with the seam between the sock and heel cup.
I do like the AllOuts a lot though. Feel like I'd roll my ankle in the lunarepics, or at least be much more prone to do so.
