Kristin, thank you for that link! And KPeriod for the extra endorsement! I managed to order for delivery tomorrow, before I boarded the plane. So excited! And Deb, thanks for the extra suggestion for an insole. I am going to try both.
All of the other suggestions are great too -- have not forgotten them.
Eliza, your description of losing your shoe in the middle of the street is exactly what I was experiencing in the airport. And it was so frustrating! Just one foot, and it didn't come all the way off, but it required a lot of effort to keep it on.
This is all making me think about my heels. I really have no idea if I have a thin or small heel. This is generally not a huge problem for me, but I do tend not to wear ballet or other slip-on flats because I don't love them. But I do love these loafers, so I am really hoping I can make them work.
Will report back. Thanks again all!
