I HATE Crocs - I mean really HATE them and the way they look - UNTIL I TRIED THESE!!!!!  Short & sweet: You can wear them to a waterpark and also out to a nice dinner.  They are comfortable and stylish looking.  (I still can't believe these are Crocs though!)  About the sizing, it's a bit tricky.  I'm a size 8.5 and I bought the 8 based on other reviews.  The length was perfect - not too short whatsoever, however the left foot was slightly snug.  Keep in mind though that even though they are made of a rubber-type material doesn't mean they won't stretch - they will.  After a few wears the left one gave some and they now fit perfectly.  My friend liked them on me so much she bought a pair.  She's a size 8 and bought the 8 and said they were just the right size for her. So go with your size or size down.  I don't think it'll matter that much.  (If my review was helpful, let me know by clicking "yes" at the end of my review!)
