"I got these in my normal 8.5 and they were really snug. I would go up at least half a size. I have other Calvin Klein heels in the same size that fit perfectly so this was disappointing. Secondly, they are made with cow fur. They shed a little and if the fur gets brushed back the wrong way it sticks up all funny. And I don't really like the idea of fur on my shoes- I missed that part in the description (which actually says pony hair but the shoes say dyed cow fur) before buying. I would exchange these for a bigger size if not for the fur."
