I wear a size 4.5/5 and have the worst time finding designer shoes. I have narrow feet and a narrow heel. Which brands run smaller? Jimmy Choo? Blahnik? Louboutin? I am looking for a pair of classic stiletto pumps, I was looking at Jimmy Choos but not sure if the pointed toe box would be too big for me. I live in the Bay Area and most of the shoes run 5.5 and up so I can't really try anything on. Any recs are greatly appreciated!
