From Hair's keyboard to my monitor:') I think you are right. Normally, they should have broken off. Didn't the girl also say, she walked by and saw her?
I don't know a lot about where she was... but all the pics are after removing her from that place. What I said is mostly speculation about why her feet would have grown like that without breaking off. Soft ground and/or lack of movement. And she had thrush, which indicates wet.
