Last product? (4)
I believe the answer is:
shoe
This clue is a double definition.
'last' is the first definition.
(thesaurus)
'product?' is the second definition.
(I have seen 'Last product' mean 'shoe' so perhaps 'product' could also mean 'shoe')
(Other definitions for shoe that I've seen before include "Trainer perhaps" , "Eg, brogue" , "What's worn" , "Sandal, for instance" , "Flash socket on camera" .)
