Runner reflecting on the subject of large clogs (8)
I believe the answer is:
smuggler
'runner' is the definition.
(synonyms)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for smuggler that I've seen before include "Importer of goods without paying duties" , "Runner" , "Contrabandist" , "Illegal importer" , "Criminal" .)
