The full series of photos is Google-able; she's taking pictures of the historically black colleges officials meeting with Trump - shoes are clearly on, as depicted here:
By the way, the whole 'feet up on the Resolution desk' furor that the right wing squawked about Obama doing - talk to Ford, Carter, W. Bush, all of whom did it first and the pictures are readily available online. I've never been a fan of feet on furniture with shoes on, but at least carefully placed flat soles on a hard surface won't permanently damage a historic artifact that belongs to The People.
Heels digging into fabric will, and anyway her whole posture, legs spread & on her knees - totally skanky, low class behavior. And dressing in skirts that short is kinda gross, too - I can't name a single professional woman I've ever seen dress like that in a professional setting. She's just playing to her right wing, masturbating-at-the-Breitbart-homepage fan club. Another disgusting trashy bottle blond right wing 'professional' drone, cut from the same cloth as Coulter, Ingraham, Lahren - they have NO principles, they're just marketing themselves as a product. GROSS!
For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.
