I like the Crocs Kadee, very comfortable and cute. A few lessons learned:
1. If possible try them on in store. I tried on a size 8 and they were very tight. I knew they would stretch out, but I also knew my feet would swell in the FL heat. I tried a 9 and kicked them off as soon as I walked they were so big. The sales person suggested I try on a different pair of size 8. Apparently no two pairs are the same, something about how they dry when they are made. Best advice, the fit was perfect.
2. Break them in before you go. The little bumps inside really rub my feet raw, especially since you can't wear socks with them.
3. If you get a pedicure before you go either do it a few days before your trip or don't let them remove all of your calluses. Part of breaking in a pair of shoes is also conditioning your feet!
