Coming from the same sequence where a slip-up revealed Chase Meridian's panty preference to millions of viewers everywhere (see slip-up "A peek at Dr. Chase Meridian's rear"), another slip-up from the film's climax involves a different part of Chase's body: Her feet.

As if getting abducted, bound, and gagged wasn't bad enough, Chase loses her shoes when she gets dropped out of the Riddler's holding tube; her black, flailing feet are plainly visible in several shots.

When Batman and Robin finally pull Chase to safety, you can see that she still has no shoes on. However, in the shot after that, you can see that she is wearing a pair of black sneakers.
