There are a lot of different ways celebrities can make a comeback in 2021, but for former pop star Kerry Katona her decision to sell photos of her feet online has supposedly seen her make millions of dollars after filing for bankruptcy twice.

But why would anyone pay for these images? For many of us feet are at best something we maintain with a nice pedicure but don't draw much attention to, and at worst utterly revolting, and yet we know that there are many people who have a full-on foot fetish.

The Quicky speaks to a psychologist and expert in sexual behaviour to find out how our feet are linked to sex, and why for some people there is nothing more erotic than the sight of a foot in different shoes and positions.
