Lightly burn hard resin shoes on the counter (6)
I believe the answer is:
scorch
'lightly burn' is the definition.
(I know that to scorch is to burn lightly)
'hard resin shoes on the counter' is the wordplay.
'hard' becomes 'h' (abbreviation used in pencil classifications).
'resin shoes' becomes 'crocs' (brand of shoes made from resin).
'on the counter' says the letters should be written backwards (counter can mean in the opposite direction).
'h'+'crocs'='hcrocs'
'hcrocs' written backwards gives 'SCORCH'.
(Other definitions for scorch that I've seen before include "Burn on surface, char" , "Superficial damage" , "Burn on the surfaces" , "Shrivel through heat" , "Singe" .)
