Quietly take ref's shoes (5)
I believe the answer is:
pumps
'shoes' is the definition.
(I know this)
'quietly take ref's' is the wordplay.
'quietly' becomes 'ps' (I can't justify this - if you can you should believe this answer much more).
'take' is an insertion indicator.
'ref' becomes 'ump' (I've seen this in another clue).
'ps' placed around 'ump' is 'PUMPS'.
Can you help me to learn more?
(Other definitions for pumps that I've seen before include "Plimsolls" , "Cycle attachments" , "leading questions" , "Water-raising devices" , "Light dancing shoes - force air into" .)
