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