I think the shoes are more of a mountain biking shoe. I have a very wide foot and had trouble finding a shoe that was comfortable. - Sidi's Mega line or Lake Cycling shoes are two good brands with wider lasts.

I think my saddle height is ok, and the front/back position ok, I've read how to do that, and believe it's were it needs to be. - ok

My knee never hurts when riding with the platform pedals. - which is a good thing as it is to be expected if you have no inherent knee problems

Not sure on cadence, my odometer does not measure that. - just try counting pedal revolutions in 5s or 10s and multiply out to 60s for rpm. Higher rpm = less pressure on your knees

I have a 21 speed mountain bike and an older 18 speed road bike. I live in a part of Arkansas where there are plenty of hills, not really mountains, just hills. - keep your cadence >90rpm and you should be fine.
