Darrel, don't know what your fabrication skills are, but I drew up something for you to consider.
I have had the idea in my head and have drawn it up several times but never made one, several folks have had left foot issues.
If anyone here can fab up something like this it could be a potential income vrs the heel toe shifts.
Just weld it on or clamp it on, and make it tall enough to put your boot in between the two pegs.
