Micheal Kors Collection Snakeskin Flats

Micheal Kors Collection size 38 snakeskin flat. Size on shoe is euro 38. Micheal Kors and Poshmark equates that to a US size 8. The store where these came from are calling it a 7.5. I feel these are closer to a 7.5 New in box, no dust covers. Feel free to ask for any measurements to be sure of size. 15020gr4
