Turn with back of foot (5)
I believe the answer is:
wheel
'turn' is the definition.
(thesaurus)
'with back of foot' is the wordplay.
'with' becomes 'w' (abbreviation).
'back of foot' becomes 'heel' (I've seen this before).
'w'+'heel'='WHEEL'
(Other definitions for wheel that I've seen before include "Change direction as if on an axis" , "Parade order" , "Turn, rotate" , "Circular frame - old instrument of torture" , "Turn in a wide 14 across" .)
