To step back in part of Oxford? (6)
I believe the answer is:
toecap
'part of oxford?' is the definition.
(I've seen this before)
'to step back' is the wordplay.
'step' becomes 'pace' (synonyms).
'back' shows that the letters should be reversed in order.
'pace' reversed gives 'ecap'.
'to'+'ecap'='TOECAP'
'in' is the link.
(Other definitions for toecap that I've seen before include "part of footwear" , "boot accessory" , "Protective cover on boot or shoe" , "Boot's metal end" , "Steel part for shoe" .)
