The Edit: Oxford shoes

Oxford shoes are defined by their closed facing, the effect of which is to make them look smart, elegant, neat and formal. Traditionally an Oxford shoe was the only kind a man would wear with a suit in town, and while changes to dress codes now mean it's fine for Derbies (AKA bluchers) and slip-ons to be worn in all but the most formal environments, it's good to be aware of the connotations that the different styles carry. Even today the Oxford remains the first choice for impeccable dressing, whichever style or colour you favour.
