Punch some footwear ..... (4)
I believe the answer is:
sock
This clue is a double definition.
'punch' is the first definition.
(I've seen this before)
'some footwear' is the second definition.
(sock is a kind of footwear)
(Other definitions for sock that I've seen before include "Hit with a powerful blow" , "Article to cover extremity" , "One going into Oxford maybe" , "Hit hard - footwear" , "This partly protects member" .)
