Piece of hose hit hard (4)

I believe the answer is:

sock

This clue is a double definition.

'piece of hose' is the first definition.
(I've seen this in another clue)

'hit hard' is the second definition.
(I've seen this in another clue)

(Other definitions for sock that I've seen before include "component of Christmas present" , "Hit forcefully; footwear" , "Woollen footwear" , "Article to cover extremity" , "impact" .)

I've seen this clue in The Times.
