Spot on. I have one pair of oxfords that are really ONLY suited form smart casual wear due to materials and trim details. Open versus closed lacing is the first dividing criterion between dress and casual, but far from the only one. While I can't say that I begin to understand the OP's aversion to derbies, all but the most formal of oxfords should work fine with a sport coat and dress trousers. At least he isn't asking for what oxfords to pair with jeans! br> But my overall recommendation would be that the OP discover the world of smart derbies for business casual wear.
