Turn with part of the foot (5)
I believe the answer is:
wheel
'turn' is the definition.
(thesaurus)
'with part of the foot' is the wordplay.
'with' becomes 'w' (abbreviation).
'part of the foot' becomes 'heel' (I've seen this before**).
'w'+'heel'='WHEEL'
(Other definitions for wheel that I've seen before include "Move in a circle" , "Change direction as if on an axis" , "Ferris -; Catherine -" , "Circular frame on axle" , "Roll" .)
