I bought these for a wedding and I wear a 7.5M most often than not but it seems in heels I run a 7 at times. These were a 7.5 but about 1/4 inch to long but fit great in the width. With that said I am a 40 year woman who has back surgery 5 years so heels are always a tough sell.  I bought a set of heel gel inserts and i danced in these all night!! I still can not believe it!  Great buy!  And the floral design i purchased are stunning in person!!
