Alden. The Shoe Mart in Connecticut carries a lot of inventory in narrow widths. They also have a semi-secret list of factory seconds that they will send to you regularly. I don't have a link but search "Shoe Mart Alden Irregulars" or something similar and you'll find it. I believe that there are threads here describing the various AE and Alden lasts.
