One going on foot in boots and all (6)
I believe the answer is:
sandal
'one going on foot' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'in boots and all' is the wordplay.
'in' says the answer is hidden in the clue.
'SANDAL' is hidden in the letters of 'boots and all'.
Can you help me to learn more?
(Other definitions for sandal that I've seen before include "Informal shoe" , "Light open shoe" , "An open shoe for summer" , "Light strapped shoe" , "Openwork shoe" .)
