These are amazingly comfortable for a heeled shoe!  They have the cushiony footbed that I love so much about Crocs, with all the style of a "real" shoe.  The overall design is excellent, and unless someone looked at them closely, they would not be able to tell these were not leather shoes.  I wore mine out to dinner and the theater the other night, and they looked great and got compliments.  I have rather wide feet, and these fit me perfectly.  My feet are not super wide, I can buy regular shoes, although shoes available in a wide width are often more comfortable.  I usually wear a 9 to 10, depending on the style and maker (more often a 10 than a 9).  I ordered these in a size 9 and they fit me perfectly, a 10 would have been way too big.  The straps are not stiff or uncomfortable at all.  I bought the black/black ones, but I like them so much I am seriously considering another pair or two in different colors.  These are going to be excellent for travel, just throw them in the suitcase with no worries, and if they get dirty you can wash them off in the sink.  I also have the Crocs Cabana high heel, and I like them a lot, but between the two styles, I like the Cyprus more.
