Asuka's feet can be seen.
End of Evangelion
Her bare feet are highlighted when Shinji chokes and lifts her up. As End of Evangelion is just one long assault on the darkest parts of your psyche, it's safe to assume that the feet in the choking scene are most certainly not for f anservice, but to highlight the disturbing nature of the scene.
