I've had them so long, not sure on the brand. I'll take a photo of them tomorrow and post it, so you can see what they are.
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.
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. My knee never hurts when riding with the platform pedals.
Not sure on cadence, my odometer does not measure that.
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.
