I'm searching for a way to clip into pedals despite my very pronated foot.
My right foot is 40-50 degrees turned out due to a torsioned shin. I pedal using my heels, which eliminates the differences in position and allows my pronated foot to turn out rather than bumping at the heel.
I'd like to modify a pair of shoes to mount SPD cleats at the heels, with the right one rotated. While midsole mounts has a small following, I've yet to find anyone mounting at the heel.
Any suggestions on a shoe likely to support this? As I look at shoes online, it's hard to tell if they have a flat heel to drill and a way to get the tee nuts on the other side, and whether they're likely to support the pull at the heel when pedaling.
