I wear a 7.5 and got the 7 as many of the reviews said these shoes ran a half size big.  Even the 7 is a tiny bit long but I think the 6.5 would have been too narrow as these shoes are somewhat narrow through midfoot, so in the end, I'm happy with the 7.  I even have wide feet and although these were snug, they didn't pinch anywhere on my foot, so it was a "good snug" means my foot won't be slipping around inside.  They definitely look more expensive than 55 bucks, has that couture clog look without the heavy price tag.  I have never bought shoes with studs on them before so I was afraid these would look cheesy, but the studs are actually a nice touch.  It's lined with a cotton floral print, very soft and comfortable to the touch.  Adds remarkable height to my small frame and I can still skip around in them :)  Overall, awesome boots that I will be planning my outfits around!
