Nope, no part of your body is traveling in a perfect circle because the part that moves in a circle is the BB spindle, and your foot is attached (hopefully) some distance away from it, and you are always dropping or raising your heel. So, no circles for your feet, unless you could somehow keep your foot at exactly the same angle relative to your hip/bb line, which is also impossible.
