These are my first Crocs, but they won't be my last.  I usually wear a 9W and these were a 10.  At first, they were too big (ie, long), but soon, the extra room was shifted to account for my wide food.  I know they're supposed to be anti-microbial, so I'm anxious to see if my feet will stink or not (they always used to before I started wearing only leather shoes).  My husband is SUPER picky about shoes' appearance and even HE likes them.  Unfortunately there are 2 holes on the arch of each shoe.  I'm guessing they are for ventilation.  Without them, they would be perfect for walking in the rain, or puddles or mud.  Sure wish I'd had these when I was riding buses to get to work.
