I tried clipless pedals, but didn't like them. I like to be able to position my foot on the pedal, where I want it, with clipless, your foot position is where it's clipped in-period. I also like to be able to get off of the pedal quickly and easily. I didn't find it to be nearly as quick and easy with clipless. I'm using "BMX" pedals-the ones with "pins" in them to keep your foot from slipping. So whatever shoes I want to wear are OK, and I don't feel any loss of efficiency-it's not like, at 67, that I'm competing in any road races. I know some people swear by them, I couldn't stop swearing at them. Many I ride with in my age category are using the "BMX" style pedals now, and getting along fine with them.
