I love Crocs.  They're a great substitute for slippers around the house and you can wear them outside.  Your feet stay cool and breathe.  They won't get sweaty like they do in sneakers/tennis shoes.  One warning: don't wear them on the treadmill.  I didn't find they gave me enough support there, but they are great for casual wear around the house or running errands.  They wear very well. I wear mine almost every day and have had them for 4 years.  Might try some other styles in the Crocs brand.
