if i where size 8 1/2 in shoes, what size uggs should i buy?

Buy a 8 they stretch you always want them to be tight at first. And plus uggs run big. I wear a 6-61/2 and i bought a 5. Hope that helps.

7, they run BIG, and I mean very big.

I'm usually a 7, or 7.5 in other shoes

but UGGS I had to get a 6 for the best fit.

P.S like other shoes they will stretch/loosen and take the shape of YOUR foot.

8, the fluff makes them bigger feeling

the girly below me is right too. if you want them to be tighter like normal shoes go down to a 7.
