Like with the previous video of Pat that I posted, she already has one sandal on as her left foot can be seen shoeless starting at 50 seconds. A closeup view of her feet in the sandals can be seen at 4:19
Jane is barefoot for at least the first 1 min & a half. About 3 minutes & a half into the video, a closeup of Jane's and Sally Combs's feet in the open-toe shoes, and another view of their feet close to 7 minutes into the video
