in the carols cover imo, I always thought her heel was just turned towards the camera a little too much.
one of the reasons why the ss cover looks so fake is cause they really turned the vibrancy and the contrast way up. a little too high actually.

her foot even looks weird in the alternate cover. weird. I still think its a combination of her foot being turned and photoshopping. like they made her foot look too smooth or something.
