Some folks are not aware that when you clip out (and in) of clipless you only do one foot at a time, and when you clip out you generally only do one foot, period, unless you are getting off of the bike, and then only when you are completely stopped. Generally you should choose the foot that feels best to you and use that foot all the time. Then you learn to shift your weight to that side of the bike at the same time (or you fall!)

I.e., when I am coming to a stop, I always unclip my right foot a sufficient distance prior to coming to a stop so that I will be ready to put my foot down as needed. When you start, you clip one foot in ahead of the other. For example, when at a red light, always keep one foot clipped in ready to go, etc.

Also, I unclip that same foot whenever I am around kids or other danger on a multi use path (MUP), or going through gravel or any other place of danger.

So far, in about 25,000 miles and seven years of riding, I have only fallen twice due to the clipless, and that was the first month I had them. Actually, I have only fallen four times for any reason (knock on wood).
