Schizoid

In Schizoid, Donna Wilkes stars as the daughter of a psychiatrist played by real-life madman Klaus Kinski.

Wilkes spends a lot of the movie's run time sulking around her mansion (daddy is very successful as a shrink) and going barefoot.

Shoes are not an option for this girl.

Neither are pants.

Mariana Hill also goes barefoot.

And Hill is barefoot during her bondage scene with Wilkes (although you don't see her feet in this scene).

Both Hill and Wilkes do some nice struggling when they're bound by the psycho killer.

But everything turns out OK, and Hill is still barefoot afterwards. A happy ending for all.
