The protagonist of Dhalgren, Delany's 1974 novel, is a man who cannot remember his own name, and is only referred to as "Kid" (or sometimes "Kidd" or "The Kid"). Throughout the novel he only ever wears one sandal, his other foot being left bare. When the Kid first entered Bellona and encountered Tak Loufer, he told him that he lost his sandal a couple of days before when he was running away from a dog. Later during the raid on the department store he loses his other sandal, and replaces it with a black moccasin boot - he had the chance to wear a pair, but deliberately opted to keep his other foot bare.
I was wondering if Delany had any specific reason for keeping the Kid half unshod. When I first read about the Kid's bare foot I was reminded of Jason's arrival at the court of king Pelias who had been warned by an oracle to "beware the man with one sandal", but I don't see any other references to the Argonauts, or Greek mythology, in the text.
