How do I tell a new partner I'm into feet?

We have been dating about two months and things are going really well. She is kind and easy to talk to, which is exactly why I do not want to mess this up. I like feet, it is a genuine part of what I find attractive, and I would rather she hear it from me than sense I am hiding something.

My problem is that I freeze up every time I picture actually saying the words out loud. How did you bring it up without turning it into some huge dramatic reveal? Keeping it casual is the whole goal here. Any wording that worked for you would help.
