Cure reported for part of foot (4)
I believe the answer is:
heel
'part of foot' is the definition.
(I've seen this before)
'cure reported' is the wordplay.
'cure' becomes 'heal' ('heal' can be a synonym of 'cure').
'reported' shows a homophone (sound like).
'heal' sounds like 'HEEL'.
'for' acts as a link.
(Other definitions for heel that I've seen before include "secure ball" , "Achilles's weak spot" , "Rogue" , "Be inclined" , "command given to setter, say" .)
