Make sure your cleats are tightley secured to the shoe. If the bolts are even a bit loose, the cleat will twist when you disengage, making the next clip in way off line. I discovered this a few weeks ago when I had trouble clipping in after a water stop. It felt like I had a rock in my cleat but after the ride, I discovered that I was missing the front bolt completely and the other two were loose enough to allow the cleat to twist off line.
