Turn with part of the foot (5)
I believe the answer is:
Here is my best explanation:
'turn' is the definition.
'with part of the foot' is the wordplay.
'with' becomes 'w' (abbreviation).
'part of the foot' becomes 'heel' (I've seen this before**).
(Other definitions for wheel that I've seen before include "ring", "Circular structure on axle", "revolutionary device", "No need to re-invent it!", "Move in a circle", "Circular steering device", "Twenty nine [TURN]", "Circular frame with spokes", "Revolutionary invention!" and "Turn in a wide curve".)
