 CONT: Cindy is wearing straplike sandals that secure around the  ankle during the fight scene between her and Brenda in Mr. Meekers  science class. When the fight breaks out, both girls are on the  ground for no more than 30 seconds, and when Cindy gets up without  her top and runs to the door, she is seen without shoes, and that  particular style could not likely have fallen off or be easily  removed during the fight.
