Is it just me or does it look like she's wearing light colored heels and not barefoot? If she's barefoot, she's walking very high arched on the balls of her feet and I would think she would have been carrying her shoes if she had removed them. But the still is kinda fuzzy, so I'm not sure if what I think I'm seeing is correct. Does anyone know if any of the media have released the actual video the still was taken from? I think it would be easier to tell.
If she is barefoot and not carrying her shoes, what did she do with them? You'd think someone would have found them by now.
