Pair of Ladies Gucci Ace Strawberry Sneakers 7.5, fits like an 8

What a fantastic pair of Gucci kicks! Unfortunately, I have tried to make these work, but I need a half size smaller. I traditionally wear a 7.5 in Gucci, but this sneaker is a bit too big for me. Comes with box, extra pair of white laces but no dust bag. In great preowned, authentic condition! Retails $750.
