Easily recognisable shoes, typically leather brogues with cream and brown panels.
In the past, when proof of adultery was required for a divorce, a professional co-respondent would spend the nite in a hotel with the woman, and leave his, readily identifiable, shoes outside the
door to be cleaned. When the case went to court, the room
boy would recall these shoes outside the
door, waiting too be cleaned, thus confirming that the professional co-respondent and the
wife had spent the nite together.
