Finally decided that now is the time for this, seeing as I have a proper bike now and on account of my feet sliding about alarmingly on flats in the wet. The strategy so far is to get used to the things by clipping in/out of them fairly often. To this end, I fitted one M520 pedal to my old hybrid, and spent a few minutes getting used to the clipping in/out of one foot whilst not moving at all. After that, I spent a half hour pootling about with one flat and one clipless pedal, trying to get used to clipping out on the side of the foot I normally put down whilst stationary. Out of that, had one fall, (it's heartening to see your foot come free of the pedal once you're beyond the point of no return, isn't it? ) Last night's project was further pootling with both pedals clipless - the dog was kind enough to assist by continually placing himself exactly where I'd flatten him if I fell.... End result, a few close calls, but no actual falls this time. I guess it's inevitable that a public clipless moment is my due at some point, but I'm quite surprised at how simple it's been to "train" myself to get used to the pedals with a little bit of effort.
