It's nothing rational.
It's the most common fetish, though.
Feet are sensitive, complex shapes and in our society, usually not seen. They encompass both purity and dirt, are associated with monks, saints and slaves, but also with just freedom.
Touching someone's feet can be a sign of humility - in India, it literally is that - but since feet can also be very ticklish, letting someone touch your feet is also a sign of either trust or surrender.
Human feet are also unique. We are the only creature that ever had feet like ours. They are possibly the best feet, since we are exceptionally good at walking - and walking bipedally at that. Nothing walks like we do, not even birds. They use their head and tail as counterweights. But we walk like a magician balancing a wand on his hand.>>104741492
