Like a brand new pair of heels (5)
I believe the answer is:
clean
'pair of heels' is the definition.
The answer and definition can be both to do with contact as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
'like a brand new' is the wordplay.
'like a brand' becomes 'clea' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'clea'+'n'='CLEAN'
Can you help me to learn more?
(Other definitions for clean that I've seen before include "Laundered" , "Absolute - pure" , "Spick and span" , "Quite" , "Squeakily hygienic?" .)
