I have just received the Gucci Princetown Mules (plain - without the fur) and they feel great, but they seem so long! Gucci shoes always seem so long in the vamp, but my foot is not all the way toward the front (of the toe) as in other mules. Is this just how they fit or should I size down? I normally wear a US 9, a European 39.5 and a French 40. I bought a 39.5 - just like my Jenni Kayne mules. Thanks!
