I've been biting my tongue too long on this subject.
the idea that knee motion is a consequence of arch collapse is incredibly short sighted. heel lateral motion (causing knee rotation) will happen regardless of whether the arch is supported if hamstring muscle contraction is in poor timing. if a rider has proper motor control the hamstrings will fire evenly holding the foot steady. if there is motor control dysfunction you will see a lateral then subsequent medial heal whipping through the stroke. this is NOT fixed by orthotics. it is fixed by teaching the medial hamstrings to control the knee rotation.
IF YOU HAVE KNEE PAIN SEE A PT THAT SPECIALIZES IN CYCLING.
come to bend and i'll show you what i mean.

The reason pedals have float is knee movement; The heel mirrors the knee. That knee movement springs directly from arch collapse. Thus, a crucial aspect of a proper bike fit is correcting that collapse.

Hi Ed and all,
Sorry to keep chiming in on this, but I actually worked with a PT who felt strongly that less float is best for lateral knee pain. I struggle with that - I tightened up my zero pedals somewhat, but too much drives me nuts. Jenny

Hey Kevin,
I'm no doctor or fit specialist, but I'm inclined to think she's
stressing something from overuse.
When she started training this year, what was her average mileage each
week and what were the longer rides she's been on? I wonder if she's
just trying to ramp up too fast.
If it were me I would write down the current set up of the bike fit
(saddle height and forward/back location, seat location, handlebars)
and then try moving things around a little at a time to see if the
pain goes away or gets worse. Then you know the bike setup that's
right for you rather than the one you're "supposed" to use. Not that
there's anything wrong with getting a bike fitting.
This may be a crazy suggestion, but I've found on longer rides flat
pedals or clips and straps work better for me than cleats since you're
able to move your feet around to avoid hot spots and vary your
posture.
