Sweet scent of feet? Not entirely! (6)
I believe the answer is:
toffee
'sweet' is the definition.
(toffee is a kind of sweet)
'scent of feet? not entirely' is the wordplay.
'not entirely' indicates a hidden word.
'TOFFEE' is hidden in the letters of 'scent of feet'.
(Other definitions for toffee that I've seen before include "Type of sweet" , "Confectionery made from sugar and butter" , "Caramel" , "sticky stuff" , "Brittle confectionery" .)
