Anyone who's ever taken a shoefie, i.e. a selfie focusing on one's footwear, knows it's a very involved process. You find a spot with an interesting, but not distracting, background. You wait until the area is cleared. You arrange yourself in an often unnatural position to take advantage of the lighting (which is always natural). You take one last look around you, and, bam, you get the shot. Of course, seeing how the sausage gets made, so to speak, is never all that glamorous. But it's reassuring that the step-by-step process, of the shoefie and the accompanying emotional roller coaster, is more or less the same, no matter who's taking it.Take, for instance, Sarah Jessica Parker. Over the weekend, she was sitting on the stoop of her New York brownstone, soaking in the fall sunshine and reading the paper. But, wait: She takes a quick glance around her, looks down at her delightfully sparkly SJP Collection Mary Jane pumps, and quickly whips out her phone to snap a picture (bird's-eye, obviously) — which ended up on Instagram shortly after, as Harper's Bazaar pointed out.
