No, as somebody else pointed out she was wearing her shoes at the time. But no harm no foul and, as a normal male, my reaction is an eyebrows raised “Whoa Girl, you are limber!” Any other aspects of my reaction I will simply not discuss here.
Could have taken off her shoes while “sitting”. Doesn’t mean she didn’t have them with her out of view, like on the other side of the couch, putting them back on when she moved around.
