Throughout the movie there is a continuity issue with the female Kryptonian Ursa who is wearing these thigh high PVC black patent boots.

But if you watch closely, your see that she changes them often throughout the movie, from high heel stilettos as shown on the street of Metropolis when she flips a manhole up and tosses it at Superman.

To when she is flying she is wearing flats, and eariler back still when she is sitting on the president's desk in the White House she is wearing elevated wedge heels.
