Authentic Valentino Logo leather Slides Black&White size 9

Valentino slides brand new in original box never worn. I bought these for a gift @ Saks OFF 5TH, unfortunately they did not fit as the person Whom this was for is a size 9. I would suggest going up a size, if you are a 8 1/2 with plump feet this will be perfectly. (FYI: if you have slim feet then size 9 will fit no need to size up)
