SO my foot doctor call it a " nice fine high arch" . . .. there is nothing fine or nice about it when you're buying shoes !!! Anyhow, i purchased this sandal thinking they would do double work for any trip. I could use them for hiking, or dressing them up with a dress . . . .YEah if i could keep them on long enough. Because i have a "fine high arch" my foot doesn't go all the way in, because of the soft material (oh they a relly soft !!!)my feet tent to slip out. I have tried to stretch them, but nothing so far. So if you have a high arch, do not buy them.
