Questions about dancing shoes (5)
I believe the answer is:
pumps
This clue is a double definition.
'questions' is the first definition.
(as in to pump someone for information)
'dancing shoes' is the second definition.
(I've seen this before)
'about' is the link.
(Other definitions for pumps that I've seen before include "needed by cyclists" , "Shoes; inflaters" , "Questions persistently; light shoes" , "footwear" , "Moves fluid or gas by pressure or suction" .)
