Barefoot on the outskirts of unknown stretch, off-grid (6)

I believe the answer is:

unshod

I'm a little stuck... Click here to teach me more about this clue!

'barefoot' is the definition.
(similar in meaning)

'on the outskirts of unknown stretch off-grid' is the wordplay.
'on' is a charade indicator (letters next to each other).
'the outskirts of' says to hollow out the word (remove centre letters) (only letters on the outskirts).
'stretch off grid' becomes 'shod' (I can't explain this - if you can you should believe this answer much more).
'unknown' with its centre removed is 'un'.
'un'+'shod' is 'UNSHOD'.

Can you help me to learn more?

(Other definitions for unshod that I've seen before include "A soft French cheese" , "Lacking footwear like horse" , "Without footwear" , "Hounds (anag)" , "barefooted" .)
