Shoe with a wooden sole (4)
I believe the answer is:
clog
'shoe with a wooden sole' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for clog that I've seen before include "Obstruct the wooden shoe" , "Congest" , "Block; sabot" , "Footwear - hamper" , "Become blocked with wooden-soled shoe" .)
