Goes past red foolishly (7)
I believe the answer is:
departs
'goes' is the definition.
('depart' can be a synonym of 'go')
'past red foolishly' is the wordplay.
'foolishly' indicates anagramming the letters.
'past'+'red'='pastred'
'pastred' anagrammed gives 'DEPARTS'.
(Other definitions for departs that I've seen before include "Goes away" , "Goes, leaves" , "Does runner" , "Quits" .)
