I always look forward to strutting the streets (actually, now in the office) in over-the-knee boots when fall/winter rolls around. They have a tendency for a commanding quite a spectacle, but it's a statement worth owning when they make your legs look miles long. A classic black pair (I suggest suede which is less aggressive than leather) is a justified investment considering they never go out of style.
