Scoundrel going after black shoe (6)
I believe the answer is:
brogue
'shoe' is the definition.
(brogue is a type of shoe)
'scoundrel going after black' is the wordplay.
I cannot quite see how this works, but
'scoundrel' could be 'rogue' (rogue is a kind of scoundrel) and 'rogue' is located in the answer.
'black' could be 'b' (as in pencil classifications) and 'b' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for brogue that I've seen before include "What might identify an Irishman" , "Footprint could be left by this" , "Shoe - tongue" , "afoot?" , "Irish or Scottish accent?" .)
