What happened with Jisoo's feet?

*Puedes activar los subtitulos* Hello everyone ! It's a new video today and it's about Jisoo ...and her feet ♡♡♡ -The truth is that I've read every comments in the video of "Jisoo is the real dancing machine", and some of them have really left me thinking ... Many of those comments are about Jisoo's feet - First of all I want to say that I'm not making fun of her, it's not my intention to do it ... And there it's no reason to do it, Jisoo is human like everyone, it's not perfect (well for me yes), but she is also like all, she have feelings like you... So... I think she has a strange problem with her feet, or maybe with her shoes, a few days ago she bend her foot, then I started analyzing the dances of Jisoo from 2016 until now and in "Playing with fire",she still does not improve in the choir part, she dances very well, I sometimes even I guide me with her fancams to dance the choreography ... but that movement in her little feet that they do in PWF ... it still does not change ... Sometimes I worry about that she has her ankles hurts for wearing her shoes and she is forcing to dance. What do you think about this ? ... Do you think it's the shoes? Jisoo is the real dancing machine//❤️ : https://www.youtube.com/watch?v=j7_4SyLHPZY Playing with fire (Piano): https://www.youtube.com/watch?v=AaWWvfG_D6k As If It's Your Last (Guitar): https://www.youtube.com/watch?v=gT2dpDpo0-s
