For sale — new shoes (7)
I believe the answer is:
loafers
'shoes' is the definition.
(Loafer is an example)
'for sale new' is the wordplay.
'new' indicates an anagram.
'for'+'sale'='forsale'
'forsale' is an anagram of 'LOAFERS'.
(Other definitions for loafers that I've seen before include "Casual shoes" , "They add cargo" , "Casual footwear" , "Comfortable shoes" , "couch potatoes" .)
