I previously owned the Crocs Patricia I sandal which is very comfortable, but the strap closest to the ankle was a bit loose which wasn't as flattering.  The new Patricia sandal has slightly different straps which I find to be more flattering.  It takes a few wearings to break in the wedge to get more arch support and for the straps to loosen, but I find they are incredibly comfortable and look better on.  I wear a 6.5 and bought a size 6 which is my normal crocs size and they molded to my feet perfectly.
