Ok, before anyone screams...
1. I have flat feet.
2. I am knockkneed. I stand (naturally) with my feet sticking out like a duck.
3. I am size 12.
I tried SPDs and they felt horrible, uncomfortable and unnatural to my knees and ankles. I currently ride flat platforms.
My feet keep falling off the side of the current pedals i have so i was thinking of getting the supposedly very wide MKS Sylvan Touring Pedals and install power grips and buy hardsoled bike shoes. I know LOOK pedals and Speedplay Frogs are supposed to be forgiving for knee freaks, but honestly that's way too much money. I'm going on a 2-week tour in June from Portland and heading east, and I like the idea of being able to use the power grips when i am home after the trip and commuting. I've heard that power grips pinch your toes after about 20 miles, but I am thinking that with hardsoled bike shoes, this won't be a problem.
I'm opening up a potential fight here, but what do you guys think...? I'd be especially interested to hear from others with the same knee problem I have.
