I can see this, especially with size 13s. I where 10s, I have short wide duck feet.
I need to be able shift gears in the rider forward or reward position when doing weight transfer maneuvers, so I have to find a happy medium for myself.
Sounds like you need.to break in your boots some more..? But aren't you mostly riding in a straight line and primarily up shifting 2-3 times and that's mostly it?
There's no freaking way I could ride even remotely aggressively and up shift and down shift correctly at that angle.
