sock

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

I believe this clue is a quadruple definition!!

'hit' is the first definition.
(I know that sock is a more specific form of the action hit)

'woollen' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?

'footwear' is the third definition.
(sock is a kind of footwear)

'item?' is the fourth definition.
(I have seen 'Item of clothing' mean 'sock' so perhaps 'item' could also mean 'sock')

Can you help me to learn more?

(Other definitions for sock that I've seen before include "Item of clothing" , "Article to cover extremity" , "Clothing; punch" , "Wallop" , "Woollen footwear" .)
