EUC Gorgeous Acid Blu Ballerina flats from Valentino size 38

This is an almost brand new pair of Valentino Ballerina flats. I received these as a gift and only wore them once. I am a size 8 and these are tight, which is the only reason why i am selling them. I think they would fit best a 7 or narrow 7.5. The color is gorgeous and very rare to find.
