Do without foot cream (7)
I believe the answer is:
unction
'cream' is the definition.
(unction can mean a cream or ointment)
I don't understand the rest of the clue.
(Other definitions for unction that I've seen before include "Anointment with oil" , "Act of anointing a monarch with oil" , "Ritual anointing with oil" , "Religious rite of anointing with oil" , "Anointing with oil; flattery" .)
