Does anybody know what the correct foot position on the pedal is?
Peddling with the balls of my feet gives more power than with the middle. Is this OK or am I risking foot or leg dammage?
Correct position is as explained above. Note that you cannot achieve this without having toe-clips, or nowadays cleats, to hold your foot in the right place.Pedalling with the balls of my feet gives more power than with the middle. Is this OK or am I risking foot or leg damage?
My shoes are set up so cleats are on the ball of my foot too but irrespective of whether that's technically correct, that's where it feels comfortable. If that wasn't comfortable I'd move it to where it was.
Your cleats should be in about nearly but not quite exactly in this position..
Why? - That is a cleat that was used with toe clips and straps to prevent pulling your foot out of the pedal. I don't think it's position has any relevance to the current discussion as the slot in the cleat located on the rear edge of that sort of pedal. I used Lyotard platform pedals which had a raised edge at the rear. Your foot may well have ended up in the recommended position but the I fail to see how this helps anyone to correctly position modern cleats.
