Gucci Blue GG thigh boots it’s a size 8 but it would fit a size 7

I’m selling Blue GG boots , I only worn these one time but it’s scuffed at the bottom because of the leather at the bottom. The bottom gets messed up easily apart from that great condition and the boots are fab just too small for me . Isn’t true to size someone is a size 7 should fit it comfortably .
