Into footwear? (4)
I believe the answer is:
shod
'into footwear?' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for shod that I've seen before include "Exclamation used to frighten animals away" , "Fitted with footwear" , "Wearing footgear" , "Like a horse that's been to a farrier" , "Supplied with footwear" .)
