I have heard that the classic Uggs run big- and that you should buy one size down- so if you normally wear a 10, for example, you should purchase a 9. What happens is that when you buy the smaller size, the material in the boot conforms and stretches to mold your foot. So the boot will feel a tad snug initially, before it takes shape around your foot.
I have tried a non classic pair on at Macy’s before, and I needed a 10- because I wear a 10 normally. They had no classic pair I could try on, and I might purchase a pair on the internet- and therefore would be unable to try on.
