Not questioning the wisdom or otherwise of what you write, but could you clarify a bit? Is there a general axiom here, forward for power, back for comfort?
Thanks.

"A question for Steve Hogg. When commenting on the lady with the short femur you mentioned the following re cleat position:
5. Make sure that the ball of your foot [centre of the first metatarsal joint] is in front of the pedal axle with the crank arm forward and horizontal. For a rough guide for shoe size metric 36 - 38, 7mm in front; 39 - 41, 8mm in front; 42 - 43, 9mm in front; 44 -45, 10mm in front. It is unlikely that your feet are bigger than that. Don't forget to move the right cleat further back again as outlined in point 3. I know that this is at variance with the commonly given advice but you will find as you try it that it works."
This is exactly the same thing I stated. Mr. Hogg states to move the cleat back not forward. Moving the ball of your foot forward in relation to the cleat is the same as moving your cleat back on the shoe.
Forward for power, back for comfort is not necessarily true. It depends of your pedaling style. Those that pedal toes down tend to go a little more forward. Those that pedal more level footed tend to have a cleat position that is neutral, and those that like to drop their heels tend to move their cleats further back. If you look at the way the cleat/ball of the foot/angle of power transmission all work here, what essentially happens is that the three act in the same plane for each scenario. What you want to do is push through the ball of your foot. This is the best point of compromise between relying too much on your calves and hamstrings(cleat under the toes), and using only your thighs and buttocks (cleat directly under your heel). The ball of the foot is designed for pushing off of things, whether it be the ground or a pedal, that's the most efficient point of energy transmission. But, due to physiological differences, some people vary their cleat position to suit their musculature or pedaling style. Generally as a rule of thumb, cleats back for more comfort. For track sprinting or high cadence pedalling, where it is natural to start locking out the ankle in a ballerina's toes down position, you may want to move your cleat forward. This will keep the pedal spindle under the ball of your foot. If you have the cleat moved forward and you're not pedalling toes down, then you are going to be putting your calves in a world of hurt.
Best thing to do is probably move your cleat back. If that doesn't work, you may want to have someone at a reputable bike shop check your position on your bike.
