1. Firstly, the calf muscles have to control the lever that is your foot from its hinge at the ankle to its attachment at the pedal. If you reduce the length of that lever, you reduce the energy wasted on your calf just keeping your foot stable.
2. Secondly, the bigger (heavier and stronger) the person, the harder they will push through the small interface between the pedal and the cleat. This larger force goes through the same tiny area of interface as a lightweight rider, but it puts way more stress on the metatarsals of the bigger, stronger, heavier person’s feet, leading to more “hot foot” pain if the cleat is located at the ball of the foot, and, in some cases, results in neuritis or neuroma between the joints of some of the metatarsals.
3. Thirdly, since you essentially shorten your leg length from the hip to the cleat by moving the cleat further back on the shoe, you can run a lower seat height with a more aft cleat. This results in lower aerodynamic drag and improved cornering due to a lower center of gravity, not to mention the possibility of a smaller frame size if you are in between sizes."
I tried to do this a few years ago and did it in small increments with moving the cleats rearward towards the centre of my shoe and lowering the seat height proportionally and I had nothing but knee pain both left and right. I did this over a two week period to no avail before I aborted the whole ideal. Moved my cleats forward again and no more knee pain. It doesnt work for everyone well at least not myself.
