In many ways its quite surprising that a fundamental thing like how you lace and tie your shoes are given such a little attention in many cases
And brown shoes go fine with brown trousers because while the color is similar, the difference in materials between trousers and shoes is enough to visually differentiate the two (unless someone is wearing leather pants, but Ill assume that excludes most Permanent Style readers.) I would personally favour an oxblood (close to Horween colour 8) or navy pair, also I think most suedes would work in any colour for a more casual look, with black suede registering less formal than black calf etc
