Pulling the trigger on an over-the-knee boot purchase (or OTKs or thigh highs, depending on which terminology you prefer) is no easy thing. We lusted after them last fall when they scored high on the trend-o-meter (note: this word does not actually exist -- we made up). The thing is, we weren't sure if we'd dig the slightly porno-ish kicks down the line. Well, looks like they're back this fall, and while OTKs still pack a pretty penny, you can find some more affordable versions. Try out our picks and rock them high-fashion-runway-style.
