I think part of the problem with modern straps is that they are too far forward, as mentioned by SF, but also, that they are only engaging the bottom of the pedal, and not the actual clasp like the hoy/baranosky/VP design.
In the past, with the SPD-r system, riders used to take the loop tang trom toe clips, cut them down, drill a hole and mount them to the clasp using the tensioning screw. That pulls the clasp up and forward, as does the hoy/baranosky/VP system. Ay e something machined or printed to hold the strap, that uses a new/longer retention screw is what's needed.
I goofed on the bottom drawing. There are supposed to be 4 legs on it to accomodate curves n the design of the pedal clasp.
