Picking up my Louis shoes tomorrow!!

I heard that the Vuitton sizes run small, some people usually have to buy a size up, so I would expect that they're also not meant for wider feet...HOWEVER, I am a US size 8/8.5 and I managed to squeeze my feet into size 38 (US size 7/7.5) mules...so...I don't know?! It depends on the shoe, I guess?
