Wellington, for example, wrongly ordered to war with foe (8)
I believe the answer is:
footwear
'wellington for example' is the definition.
(wellington is a kind of footwear)
'wrongly ordered to war with foe' is the wordplay.
'wrongly ordered' indicates anagramming the letters (I've seen this in other clues).
'with' means one lot of letters go next to another.
'to'+'war'='towar'
'towar' put after 'foe' is 'foetowar'.
'foetowar' is an anagram of 'FOOTWEAR'.
(Other definitions for footwear that I've seen before include "Shoes, boots, sandals etc" , "Boots, shoes, slippers etc" , "Oxford maybe" , "Sandals and slippers" , "Sandals, e.g." .)
