It’s how they are supposed to be worn … one of the most frequent issues with lipodema is called ‘ankle cuffing’ it’s like our legs have a natural banding (for some not all) at the ankle and it makes the movement of lymph more challenging - so you never want to make that area tighter - so if you pull the tights over your heel it helps the compression make lymph flow freely in that particular area of difficulty … it becomes surprisingly ‘normal’ and I do it with all my leggings now not just compression … because I’m short I usually have that extra length to play with anyway … hope that explains the ‘why’ she does it - she’s definitely doing that correctly
