Christian Louboutin Pigalle Follies 100 Patent

Pigalle Follies 100 Patent Size 37. Used TWICE AND COME WITH BAG, BOX, and Authenticity card. My bf gifted them to me and I tried to wear twice but they are 1/2 an inch too big. There’s absolutely no way I can walk on them, without them coming off. I’m a size 61/2- 7 women and I think in these, I’m a 36.
