I know from experience that Gucci shoes run either small or large in size according to style. Does anyone know if the Peyton loafers (mid heel) or the Peyton mules are true to size? I'm a size 7.5 (37.5 euro) and I fit in an 8 (38 euro) when it comes to Princeton mules, yet I have fit into a size 7 (37 euro) into the Ace sneaker.
