Ah, Diana, you may have solved my dilemma--my heels have absolutely no jut out from my ankle, and, as a matter of fact, might actually go in a bit from my ankle line. I can see the tape idea working, but I'm not sure I wouldn't have to use duct tape wrapped several times around my heel and ankle to get those footies to stay in place, which sort of defeats the bare-foot look!
The only footies that even remotely stayed in place for a few blocks were those weird golf footies with pompoms at the top of the heel. But I have the distinct feeling that Angie would give those a thumbs down, even if the pompoms were in her favorite citron!
