Could you be thinking of a different show? Perhaps:
* Grey's Anatomy: This popular medical drama features a lot of feet, especially in surgical scenes. However, the opening credits primarily focus on the actors' faces.
* The Anatomy of a Murder: This 1959 film uses feet in the opening credits, but it's not a television show.
If you can provide more details about the show you're thinking of, I might be able to help you identify those feet!
