foot condom
Those little one-time-use nylon socks they provide in some shoe stores to use when trying on shoes. They usually come in a box like tissues.
Don't try on that sandal barefoot, use a foot condom!
Condom Foot
is what happens when you have a bunch of shitty friends who wrap contraceptives around your feet as you are blackout drunk. Caution- may cut off blood circulation in the foot area.
“K got shitfaced last night, and everyone gave him condom foot.”
