There is a scene in Rush Hour 2 when Chris and Jackie are watching Roselyn Sanchez through a hotel window. The entire time they are watching her, she has on a pair of dark-colored pumps. The shoes are closed-toed, they have a very thin heel, and a strap across the back. She still has these shoes on when they bust in her room and take the "bomb" to the roof.

When Roselyn goes up to the roof to get Chris and Jackie, she has on a light-colored pair of shoes. These shoes have a thick heel, no strap across the back, and are open-toed.

There is no reason for her to have switched to a different pair of heels in that time span. Since the choice was made to do a closeup on her feet, this was definitely a continuity slipup.
