Sturdy walking shoe (6)
I believe the answer is:
brogue
'sturdy walking shoe' is the definition.
(brogue is a type of shoe)
This is the entire clue.
(Other definitions for brogue that I've seen before include "Worn" , "Thick and heavy shoe" , "Stout leather shoe" , "Shoe - tongue" , "Patterned shoe, accent" .)
