No offense, but this reads like someone desperate for validation over their over-romanticization of strange women's feet.
A woman "showing her feet" (gasp) isn't exactly flashing her tits, and we as a community really need to stop acting like it is. Women go barefoot or wear sandals every goddamn day, and they deserve to do so without being pestered by some heavy breather with a wharton wheel and a camera phone.
There are a lot of things that require "guts" to do, but are still things that you should not do. This is one of them. If you really want to develop confidence, try talking to women, getting into relationships (friendly or otherwise) with them, and maybe, just maybe, they'll not only show you their feet but maybe let you... touch them as well. (double gasp!) As an added bonus, you can rest assured that she's letting you touch them because she wants you to touch them, and not because you tricked or pressured her.
"Prank videos" require guts, too. And nobody likes people who film prank videos. Mull over that for a moment.
