Discarding wellie, at home with foot problem? (7,3)

'discarding' is the definition.
(to boot out is to oust or discard)

'wellie at home with foot problem?' is the wordplay.
I cannot quite see how this works, but
'wellie' could be 'boot' (wellie is short for Wellington boot) and 'boot' is found in the answer.
'at' could be 'in' and 'in' is located in the answer.
'foot problem?' could be 'gout' (disease affecting feet bones) and 'gout' is found within the answer.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
