For sale – new footwear (7)

Ross

I believe the answer is:

loafers

I'm a little stuck... Click here to teach me more about this clue!

'footwear' is the definition.
(I've seen this before)

'for sale aeur new' is the wordplay.
'for sale' anagrams to 'LOAFERS'.
But, I am not clear how this is indicated.

Can you help me to learn more?

(Other definitions for loafers that I've seen before include "Comfortable shoes" , "couch potatoes" , "Casual shoes" , "Casual footwear" , "They add cargo" .)
