Concluding it's foot-shaped (4)
I believe the answer is:
last
This clue is a double definition.
'concluding' is the first definition.
('last' can be a synonym of 'concluding')
'it's foot-shaped' is the second definition.
(shoemaking tool)
(Other definitions for last that I've seen before include "Rearmost" , "It helps cobbler" , "Latest" , "Form on which a shoe is made" , "stay at the back" .)
