I guess in my original post about Columbia's Pajamas I never included her shoes. Although I can't tell if she's wearing shoes during Touch-a, you can clearly hear them when she gets up to leave the dinner table. The best time to see them is during her monologue before she gets Transduced. It's also a great capture of that ridiculously long string hanging from her waist.
They're just basic black mules (slide-on slippers with a heel).
They're also on her feet during her Eddie's Teddy verse, but so hard to see without lightening the screenshots substantially...
