Wholehearted approach in terms of footwear etc. (5,3,3)
I believe the answer is:
boots and all
'wholehearted approach in' is the definition.
The definition suggests an adjective which matches the answer.
'terms of footwear etc' is the wordplay.
I cannot quite see how this works, but
'of' could be 'o' and 'o' is present in the answer.
'footwear' could be 'sandal' (sandal is a kind of footwear) and 'sandal' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for boots and all that I've seen is " without reservation on Bondi Beach".)
