Walk home (3)
I believe the answer is:
pad
I believe this clue is a double definition.
'walk' is the first definition.
(padding is a kind of walking)
'home' is the second definition.
(pad can mean someone's home)
(Other definitions for pad that I've seen before include "Helicopter landing area" , "Walk with soft steady steps" , "In slang, one's flat or bedsitter" , "Sheets of paper fastened together along one edge" , "Walk softly around the apartment?" .)
