Pull part of a shoe, we're told (3)
I believe the answer is:
tow
'pull' is the definition.
(tow is a kind of pull)
'part of a shoe we're told' is the wordplay.
'part of a shoe' becomes 'toe'.
'we're told' indicates a 'sounds like' (homophone) clue.
'toe' is a homophone of 'TOW'.
(Other definitions for tow that I've seen before include "Pull using cable" , "Pull along behind, say barge" , "form of flax" , "Haul" , "Tug" .)
