I have always been very comfortable with my crocs and have been wearing them since around 2006 or 07.  There is hardly a day goes by that I do not have them on and will buy another pair when these wear out.  The soles is the only thing that get a hard wear and when this happens they can become a little slice when in a wet place.  I also have a pair of enclosed, laced ones I wear when it rains.  With a sock or without I enjoy them.
