Can we like, do that?
The tag gets added to basically every barefoot image on the whim of the uploader. There's not real any consistency here. For example, post #5817921 is tagged with toes, but the feet aren't even the focus here, she's just barefoot.
And when the feet are the focus, I think foot focus is enough as is. I'd like to deprecate the tag.
The tag pretty much behaves like the hips tag back then (now aliased to hip focus). The tag got added to every image where the character had exposed hips, meaning it was added to every swimsuit image ever and more.
