Awkward to walk on, like a light shoe? (8)
I believe the answer is:
slippery
'awkward to walk' is the definition.
I can't tell whether this definition defines the answer.
'on like a light shoe?' is the wordplay.
'on' says to put letters next to each other.
'like' becomes 'y' (similar in meaning).
'a light shoe?' becomes 'slipper' (I've seen this before).
'y' after 'slipper' is 'SLIPPERY'.
(Other definitions for slippery that I've seen before include "Hard to grasp, like an eel" , "Evasive like an eel" , "Not to be trusted" , "Hard to grasp or walk on" , "found difficult to get hold of" .)
