Cads’ shoes

SIR – Neil Sewell-rutter (Letters, July 27) refers to two-tone shoes as spectator shoes. This type of shoe, associated with cads and bounders, picked up the nickname of corespondent shoe in the Thirties. In English law the term co-respondent is used for the third party in a case of adultery, and the then Prince of Wales, who went on to become Edward VIII, was known to love wearing them.
