Winged sandals identified in short story and song (7)
I believe the answer is:
talaria
'winged sandals' is the definition.
(I've seen this before)
'short story and song' is the wordplay.
'short' means to remove the last letter.
'story' becomes 'tale' (synonyms).
'and' means one lot of letters go next to another.
'song' becomes 'aria' (piece of music in an opera).
'tale' with its last letter removed is 'tal'.
'tal'+'aria'='TALARIA'
'identified in' is the link.
(Other definitions for talaria that I've seen before include "Winged sandals of Hermes" , "Winged sandals of Mercury" .)
