DS asked this question a year ago. The feedback he received was that several brands were considered acceptable. Black,low quarter, leather, lace up was generally the guidelines he received. Called the Citadel store they were not very helpful with specific brand and model. In a month or so you will receive required inprocessing forms and a list of all the items your need to bring with you. On that list is the specific brand and model number of both the boots and the shoes. I can no longer remember the specifics but I believe it was a Bates uniform shoe in a model that the postal service also uses. I don't know if any one would notice a different manufacturer, since most of these shoes look alike, but since he was a freshman he opted to buy the exact model recommended. He bought them in June and felt he had them broken in when he arrived.
