I'm hoping someone could clarify this for me. Are these sandals sizing Italian or French? I'm asking this because Net-a-porter says it's Italian sizing, while K Jacques website says they are french sizing. I have directly emailed the brand and they also confirmed this. I'm IT37 and my foot measures 24 cm, so I ordered size 38 of the Gina flat sandals. However, they feel like they are half a cm too big (this is when my toes are on the white stitching that frames the soles, not right at the edge) Is that how they are supposed to fit? Any clarification would be greatly appreciated. TIA!
