What can I say- these are great.  I really sort of hate crocs, but got suckered in by the mary jane look and actually wear these to the office all the time now.  And around town.  They are cool, lightweight, comfortable, and so easy to slip on or off.  They fit slighty small- I am really a 1/2 to whole size smaller than the size I wear, and when I'd initially ordered a pair in that size I was pretty uncomfortable. (I can't comment on the return- since I gave that pair to a jealous friend- but as a rule, I've not had a problem with Amazon returns.)
