There is a shoe that is popular with some kilt wearers called a Glenfinnan. It is supposed to be modeled on the shoes Bonnie Prince Charlie wore, although it is a functionally modern shoe rather than an accurate historical reproduction of an 18th century shoe (for instance, it has right and left shoes, rather than being interchangeable). At any rate, it is black leather with a big buckle and might be the look you are going for.
