I am a hopeless Crocs fan.  My feet would never forgive me if I went back to "regular" shoes.  Granted, no one will ever look at me and see a fashion queen.  Good thing I have strong self-confidence and a "nice personality" (small comfort when I was a young thing, but not so bad now).

When my medical office was bought out by a large health care organization, shoes with holes were no longer allowed.  I got these and they are perfect.  Great fit, super comfortable.  I was concerned they might not "breathe," but that is not a problem.

I can never give a single answer when asked what size shoe I wear - depends on the style, brand, etc.  I am a woman with BIG feet (my thoughtful ex used to call them aircraft carriers).  Most women's shoes don't even fit me.  For this classic style of Croc, I take a ridiculously small size.  For "dressier" styles of the SAME brand, I need larger.  In some other brands, I need a larger-than-usual size.  This is all to say you shouldn't buy these shoes without trying them on, or knowing from previous experience what size you really need.
