Hobbling (4)
I believe the answer is:
lame
'hobbling' is the definition.
(both can mean walking with difficulty)
This is all the clue.
(Other definitions for lame that I've seen before include "Having impaired walking ability" , "Limp - fabric" , "Weak and unconvincing like injured foot" , "Halting or unconvincing like poor excuse" , "Disabled in the feet or legs" .)
