Crossword Genius

Roll wide part of shoe (5)

Ross

I believe the answer is:

wheel

'roll' is the definition.
(I know that roll can be written as wheel)

'wide part of shoe' is the wordplay.
'wide' becomes 'w' (abbreviation e.g. in cricket).
'part of shoe' becomes 'heel' ('heel' is part of 'shoe').
'w'+'heel'='WHEEL'

(Other definitions for wheel that I've seen before include "No need to re-invent it!" , "Change direction as if on an axis" , "Go round" , "Move in a circle" , "Fly in a wide circle" .)

I've seen this clue in The Times.
