I have been contemplating clipless pedals as the next logical step. So after a bit of research and reading this question and it's answers
I find myself a bit unconvinced mainly because nothing covers something I notice myself doing a lot.
I change my feets position on the pedals quite a lot for no conscious reason, it feels right when I'm going uphill and my feet get hot spots at other times so I change to another part of the foot for a while. Mostly I move them a bit forwards or back, but I also move them outwards sometimes. Particularly when coasting I change position. For the first six months I wore jandals (flip flops), but for about a month I've been using very cheap flat soled sneakers with a pretty rigid sole which work really well for me.
When zooming around a tight corner I also take my inside leg off the pedal as you do on a motorbike, I've never come off on a corner but it's a reflex action when leaning I think. I lean right over so couldn't pedal anyway without the pedal hitting the ground.
I'm pretty old and I don't recall anyone back in my younger days using anything but normal pedals, not that I'd have noticed. I had assumed moving your feet around was normal, but now I'm wondering if I should train myself out of the habit. Possibly it's all in my mind, but making a small change when working hard on a hill seems to use the leg muscles slightly differently and give me a stamina boost (I don't stand in the pedals).
I'm not racing anyone except myself, I just commute, but I like speed and I like pushing my limits.
My question is, how important is it to keep your feet in one position on the pedals. How much of an advantage do you gain from doing so?
