I have used spd style and Speedplay frog clipless pedals. My current shoes are too Chinese and I have wide feet. So I have some flat pedals on my bicycle until I can get some custom shoes. It seems to me that many people make clipless pedals out to be scary or to hard to use. I have noticed that some of my friends in the past were lazy and did not practice before venturing out onto the road. One individual had such anxiety that he failed to release his foot while stooping just before several cattle guards. Proper fitting bicycle shoes and a retention system allow you to travel safer and further down the road. Feet slipping or shaken off of pedals because of bad road surfaces or avoiding obstacles does happen and that platform pedal digs into your leg. Bruised feet from wearing street shoes on long rides. How many Tour de France riders use flat pedals.
