In Pacific Rim, there seems to be a recurrent motif of the right foot.
First, Mako loses her right shoe when she is a child, and is shown running with only her left shoe. Her adoptive father, Stacker Pentecost, later gives her this shoe as a symbol of trust.
Later, Hannibal Chau gets swallowed by a baby Kaiju, and loses his very distinctive right shoe in the process. In fact, the character is first introduced in the movie by his shoes. In a post-credit scene, we see that he survived and ask for his shoe.
Finally, in the final battle, the Gipsy Danger gets its right leg badly damaged
Have any of the creators commented on this apparent obsession with (right) feet?
