If your clipless pedals are holding your feet in a position that is not in their natural lay, you can trigger knee pain. To look for the natural lay of your feet, peal your shoes and socks off, wet the bottom off your feet and walk across dry concrete and look how your heal toes line up. Most people walk with the toes angled out relative to the heals, some walk with the toes and heals in the same line as you walk straight ahead, some walk with the toes angled inward to the heal and still a smaller number with one foot in a different lay than the other foot. Once you know the lay of each foot, adjust the cleats so that when the shoes are clipped in, the shoe falls in line with the natural lay of each foot. Remember when you are adjusting the cleats from the bottom of the shoe, the cleat position is upside down and is 180 degrees out of synch with the shoe lay when the shoe is flipped back over and clipped in. So to rotate the heal inward and the toes out you would rotate the cleat position with the toe end pointing inward and the heal end pointing outward.
