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.
