Clog, for instance (4)
I believe the answer is:
shoe
'clog for instance' is the definition.
(I know that clog is a type of shoe)
This is the entire clue.
(Other definitions for shoe that I've seen before include "Last product" , "Brogue or loafer, perhaps" , "something afoot" , "Camera mounting" , "Item of footwear" .)
