Assuming you would like an in-depth explanation of what Feet Finder is:
Feet Finder is a website that helps people find other people's feet. It's basically a foot fetish dating site. People can upload pictures of their feet, or search for other people's feet to find someone they're attracted to. They can then message each other and arrange to meet up.
The website has been designed so that it's easy to use and navigate. There are different search options available, so you can narrow down your search to find exactly what you're looking for. You can also filter by location, so you can find someone local to you.
There is a fee to join the website, but this allows you access to all the features and gives you the best chance of finding someone compatible with you.
