British scoundrel’s shoes (7)
I believe the answer is:
brogues
'shoes' is the definition.
(brogue is a kind of shoe)
'british scoundrel's' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in BBC).
'scoundrel's' becomes 'rogue's' (rogue is a kind of scoundrel).
'b'+'rogues'='BROGUES'
(Other definitions for brogues that I've seen before include "Lace-up shoes" , "Oxford and Derby, for example" .)
