Hmm. This is all mind bending. I wonder if I’ve just ridden for so long in shoes that allow heel slip that my pedal stroke has evolved to compensate. I still can’t really fathom what movement would make the heel move, it seems like you’d have to be pushing down with your toes on the upstroke?
Either way, the heel lock isn’t going to work for me. Holy **** it’s uncomfortable. I wish I could order another set of 2008 Specialized BG Pros before they started messing with their fit.
