Hi there, I don't live near a Alden dealer so I have to order them by mail. I'm wondering what size will fit me on the Barrie & Trubalace lasts? I already know that I have to size down 1/2 size lengthwise but I am unsure of the fitting width wise? I usually wear 11E for normal shoes & 11.5E for running shoes. I have low (but not flat) arches as well. Any help and advice will be most appreciated. Thanks in advance.
