It's one thing to live with a few MMs to a CM of toe overlap, especially if one doesn't ride in traffic much. But increase the overlap to 4ish CM... Try adding a pencil or wire extending 3+ CM out forward of your current shoe's front and ride the bike to see if that much overlap is workable for you. I know I would never design a bike for another with so much overlap.

Your challenge is much like the wish for minimal reach to the bars that smaller women have suffered with. One industry solution was to run a smaller ft wheel to reduce overlap, whether you have the same size rear wheel or not. This is why I chose 559 x 38 tires/rims for my touring bike. If I were to run 38ish MM tires on a 622 wheel and include the fenders I would have close to 2+ CM of overlap. The other beauty of smaller tire diameters is that the steering geometry can retain snappier handling specs, no need to chopper out (or actually "back" as the front center would remain nearly the same) the steering angle to lose TT length.

I could rant on the current industry solutions for wanting short reaches but I won't Andy
