Healthy popular guy initially not returning trunks and footwear (10,5)
I believe the answer is:
wellington boots
'footwear' is the definition.
(I've seen this before)
'healthy popular guy initially not returning trunks' is the wordplay.
I cannot really see how this works, but
'healthy' could be 'well' (similar in meaning) and 'well' is found within the answer.
'popular' could be 'in' ('in' can mean trendy) and 'in' is found within the answer.
an anagram of 'not' is 'ton' which is present in the answer.
'trunks' could be 'boots' ('boot' can be a synonym of 'trunk') and 'boots' is found within the answer.
A single letter 'g' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'and' acts as a link.
Can you help me to learn more?
(Other definitions for wellington boots that I've seen before include "calves protected by these?" , "Footwear" , "rubber items? - with 24a" .)
