Endure as a model (4)
I believe the answer is:
last
This clue is a double definition.
'endure' is the first definition.
(I know that endure can be written as last)
'a model' is the second definition.
(model used by a shoemaker)
'as' is the link.
(Other definitions for last that I've seen before include "Bringing up the rear" , "Latest" , "Hold out" , "ending a series" , "Cargo to stay fresh" .)
