Selected socks needed in cold North (6)
I believe the answer is:
chosen
'selected' is the definition.
('chosen' can be similar in meaning to 'selected')
'socks needed in cold north' is the wordplay.
'socks' becomes 'hose' (I've seen this before).
'needed in' is an insertion indicator.
'cold' becomes 'c' (eg on taps).
'north' becomes 'n' ('N' can be a synonym of 'north').
'c'+'n'='cn'
'hose' placed into 'cn' is 'CHOSEN'.
(Other definitions for chosen that I've seen before include "'''Many are called, but few are ...'' (Bible) (6)'" , "If you're one of these few, you're very privileged" , "Selected - Japanese name for Korea" , "Elected, picked" , "Selected, picked" .)
