There was a short lived product that made traditional pedals and toe clips work rather well, called Super Strap. Well, yes... that's what marketing came up with but anyways I think its demise was because of its launch right when clipless pedals became mainstream... 1989 -1990, though clipless was essentially intro'd in '85.

I still have a pair of the Super Strap. Very well made and should last another couple decades. Retrofits to any toe clip, its a heavy duty nylon strap with teeth for ratchet action buckle - visually like on a ski boot. A simple flick up on the buckle allows a large opening for foot removal. The -non webbed- nylon is rigid enough to hold shape vs. leather. Fine tuning tension is simple.
