Outrage as open shoe gets caught (7)
I believe the answer is:
scandal
'outrage' is the definition.
(synonyms)
'open shoe gets caught' is the wordplay.
'open shoe' becomes 'sandal' (I've seen this before).
'gets' indicates putting letters inside (gets can mean captures or absorbs).
'caught' becomes 'c' (cricket abbreviation).
'sandal' placed around 'c' is 'SCANDAL'.
'as' acts as a link.
(Other definitions for scandal that I've seen before include "Event causing public outrage" , "It injures reputation" , "Public outrage; gossip" , "Subject of Sheridan's school" , "subject for play school" .)
