I usually wear a 6.5 US shoe. I followed suggestions in other reviews regarding sizing and it fit perfectly. I love these shoes. I usually wear heels but am in recovery from a foot injury. I'm not supposed to wear heels for several months. I tried these on and I love them. They're cute and comfortable and worth every cent. I can't quite wear them over my injured foot yet as I'm in a boot until I'm better, but these will be my go to shoes.
