Lazybones, one goes on foot (6)
I believe the answer is:
loafer
'lazybones' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for loafer that I've seen before include "maybe put foot in it" , "one going on foot?" , "One shirking work" , "Comfortable shoe or a do-nothing" , "Wastrel - shoe" .)
