In a sane world, there would be no market for feet pictures in any capacity.
One step down from there, is a world where gorgeous women could sell pictures of their well manicured feet but in a manner incidental to the rest of their body.
We’re in 🤡 🌎 ! In this age, safe to say, the dirtier and gnarlier a dude’s feet, the more marketable they probably are to other dudes. Bonus if you have more or less than 5 toes per foot.
