The foot fetish is a familiar cinematic trope, going back to the classic films of Luis Bunuel. This Penthouse vignette video is among the better examples of well-produced porn shows spotlighting the kink.
Currently there are innumerable videos for the fans, but they tend to be of the gonzo variety, as witness the rather gross and grotesque offerings of Belladonna. I enjoyed a segment in the all-over-the-sexual-map video by Tiffany Mynx TIFFANY & CUMPANY where she really got into massaging a guy's boner with her feet, but STILETTO is even better.
I think the reason it works is that each segment, particularly a threesome involving Holly Wellin, presents arousing "straight" sex in addition to the advertised pedal action. I bought the DVD as a newly recruited fan of Rebecca Love and wasn't disappointed -she is hot and reason enough to watch.
Give credit to Randy Spears, perhaps an over-exposed porn actor whose sullen manner eventually got on my nerves over the years (especially since so many of his films and videos got plenty of softcore play in bowdlerized versions on The Playboy Channel and other pay-cable outlets), for directing a crowd-pleaser that transcends its fetish pigeonhole. Not on-screen but on the crew are several classic personalities from porn's Golden Age, including Veronica Hart and Sharon Kane.
