Notes shine on article of footwear (6,4)
I believe the answer is:
tennis shoe
'footwear' is the definition.
(tennis shoe is a kind of footwear)
'notes shine on article' is the wordplay.
'notes shine' can be anagrammed to 'TENNIS SHOE'.
But, I'm not clear how this is indicated.
'of' is the link.
Can you help me to learn more?
(Other definitions for tennis shoe that I've seen before include "Sports footwear" , "court wear" , "item of footwear" , "sporting gear" , "Canvas footwear" .)
