I read a few reviews before purchasing and I think the bulk of them were spot on.  These are so very comfortable I don't want to take them off.  With standard running shoes I looked for the moment in the day I could remove my shoes and let my feet relax.  Now they are relaxed all day long.
I am not a runner, but I do run on a treadmill a few times per week.  I bought them for everyday wear and will soon be looking for another pair.  Not because mine are worn, because I enjoy them that much.

Feel that they are true to size.  I bought an 11 2E.  Fits well enough to support my wide foot with no cramped feeling whatsoever.  I "might have" gotten by with a standard width, but I don't feel like this size is sloppy, so I would buy a 2E again.  According to a plate shoe sizer I am an 11 2E.

Also, they are low to the ground so it you see a puddle, your feet/sock will get wet.  Expect it.
