All,
I've had a professional fit at Specialized in Boulder, so I'm pretty dialed in. After the fit I got a Dura Ace two-side power meter. Same crank lengths, all that. Saddle is fine, no hip rocking.

As part of the fit I've got my left cleat shimmed 2 degrees to help with outside toe pain.

Interesting on the power meter; over a 20 to 25 mile ride, my left/right power distribution is normally 55% - 45% or more favoring the left side. Never in a million years would I have guessed that I had lop-sided power that much to the left based on feel alone. This is not a new, one-off experience as I've had the power meter long enough to see a consistency in these numbers.

Now my question. Could my legs be of different length and/or could the 2 degree shim on my left cleat be causing this? I'm thinking about adding a cleat riser to my right cleat. Do you think this might help? When I consciously pedal to even power, my left foot hurts even less than when I added the shims.

Any thoughts to get to even power balance, other than pedaling to even power based on the meter? I'd prefer to not watch it all the time.

Thanks.

Glenn
