I had a lot of fear using clipless pedals at first. My main problem was that I would clip out my right foot and my weight would be leaning left and I would fall over even though I did have a foot clipped out. My husband taught me to turn my front wheel AWAY from the clipped out foot (i.e. clip out right, turn wheel to the left) so that the weight of the bike will naturally fall to the side of the clipped out foot. Also, using the trainer really helped me figure out clipping in/out and getting used to switching gears.
