get them from zappos, then you can return for free if they don't fit. They also ship free overnight!! I have found different style ugg boots do fit differently. My classics run 1 size large. My raniers run true to size. I just ordered Rina and they told me to size up 1/2 size and they were huge, so I returned and sized down like classic and they are perfect. I have never tried zippered Uggs...
