Finish getting toes dry somehow (7)
I believe the answer is:
destroy
'finish' is the definition.
(thesaurus)
'getting toes dry somehow' is the wordplay.
'getting' is a charade indicator (letters next to each other).
'somehow' indicates anagramming the letters.
'toes' after 'dry' is 'drytoes'.
'drytoes' anagrammed gives 'DESTROY'.
(Other definitions for destroy that I've seen before include "Annihilate" , "'Demolish, ruin (7)'" , "Soundly defeat" , "Ruin, put an end to" , "Demolish; pull down" .)
