Rascal cutting top off sturdy walking shoe (5)
I believe the answer is:
rogue
'rascal' is the definition.
(both can mean a scoundrel)
'cutting top off sturdy walking shoe' is the wordplay.
'cutting top off' means to remove the first letter.
'sturdy walking shoe' becomes 'brogue' (brogue is a type of shoe).
'brogue' with its initial letter taken off is 'ROGUE'.
(Other definitions for rogue that I've seen before include "Bad person" , "Wild animal driven away from herd" , "Miscreant" , "one behaving atypically" , "Villain - freak" .)
