Showed we went in Boots (4)
I believe the answer is:
shod
'in boots' is the definition.
(I've seen this before)
'showed we went' is the wordplay.
'went' suggests deleting specific letters (selected letters go away).
'showed' with 'we' taken away is 'SHOD'.
(Other definitions for shod that I've seen before include "Not with bare feet" , "Fitted with horseshoes" , "Like a horse that's been to a farrier" , "Exclamation used to frighten animals away" , "Fitted with shoes" .)
