Boy gets scoundrel's shoes (7)
I believe the answer is:
brogues
'shoes' is the definition.
(brogue is a kind of shoe)
'boy gets scoundrel's' is the wordplay.
'boy' becomes 'b' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'gets' means one lot of letters go next to another.
'scoundrel's' becomes 'rogues' (rogue is a kind of scoundrel).
'b'+'rogues'='BROGUES'
Can you help me to learn more?
(Other definitions for brogues that I've seen before include "Lace-up shoes" , "Oxford and Derby, for example" .)
