Hi, they have the particular shoe that I want at the factory shop but they only have it in an E fit which is their normal fit. I have a pair of churches city line shoe and that is a G fitting (wide). Now, how do I know if an E fit from JL will fit? I dont really want to go to the store in Jermyn St (probably embrassing). This is probably a difficult question to answer but does anyone know how else I could try and see if the E fit will do for me?
