Crocs are frustrating, especially when buying online.  From one style to the next they seem to be so different in length and width.  Though I usually wear a size 8, I own a pair of Crocs thong style sandals in 7 and they fit well and are so comfortable.  I've also tried a mary jane style in a size 8 and found them too short. After reading reviews, I thought the Cleo might work for me.  My foot is a little narrow, but the comments seemed to indicate that this shoe ran narrow.  I bought two pairs in size 8 in different colors, and was so disappointed that they didn't fit!  Though the length was fine, they were much too wide.  Crocs needs to work on some sort of consistency in their sizing.  Kudos to Amazon on making the return easy.
