so I wear usually anywhere between an eight and a nine these are six and a half and I can fit my feet into them and it isn't uncomfortable.... so I'm definitely saying they are a very big six and a half. they have been very gently worn and kept in a smoke-free home. These special slouchy ankle boot are an absolute great accessory to a distressed hem on your favorite winter or fall skinny jeans! with a skirt they'll highlight your legs, especially your calves!
