I was riding on my around town bike today doing some hill work, I didn't have my road bike with me; the bike has no cleats or a cage. I was messing around with foot positions since the bike is not geared for what I was doing. I tried positioning my heel all the way forward and then precede to move them back , And I got to say I felt more energy when my foot was positioned with the arch and heal over the center of the pedal than I did with normal foot position.

Has anyone tried to move the cleat back and what results have you noticed?
