Those are very blurry pictures. What are you trying to find? There isn’t anything in them that looks like it doesn’t belong with them in the ocean after surviving a plane crash.
The foot is Fuddy’s and makes sense with the way she is lying. She is lying with her head on the right of most photos and her legs go toward the left and closer to the camera.
I saw your photos but why would anyone ever have to pick out anything in those blurs? To what purpose? I don’t think but I could be wrong that desperately searching for cause of death in those grainy images will bring you satisfaction. I don’t see how.
For the yellowish protrustion to be Fuddy’s shoe, where we see the entire oval created by the sole of her shoe, what angle would that shoe have to be to the camera? Would it work to have the shoe perpendicular to the camera, or would the shoe have to be parallel to the camera?
Take a shoe with a white sole and hold it in front of you so that the person wearing the shoe would be in the position you believe Fuddy to be in those images and the shoe is right in front of you. How much of the sole do you see? What shape is it?
Now put the sole so you can see the entire oval shape made by it? When you are able to see that shape, where would the person wearing the shoe have to be?
The full images can be seen at my blog so you can see context or see the images smaller. These are the same resolution of photos as the photos in which you saw the other details you saw.
Here are three shots in sequence from the video:
