One reshaped in end part of the foot (7)
I believe the answer is:
toenail
'part of the foot' is the definition.
('toenail' is part of 'foot')
'one reshaped in end' is the wordplay.
'reshaped' is an anagram indicator.
'in' means one lot of letters goes inside another.
'end' becomes 'tail' (tail is a kind of end).
'one' anagrammed gives 'oen'.
'oen' inserted within 'tail' is 'TOENAIL'.
(Other definitions for toenail that I've seen before include "Digital cover-- 21 across (anag)" , "Digital coverage" , "Growth from foot" , "woman in labour" , "Footplate, perhaps" .)
