Pedaling dynamics are based on having the "ball" of the great/big toe over the pedal spindle.

One suggestion would be to use some method to cant the foot.
Either inside the shoe with simple under the insole shim(cardboard or plastic would be a way to test this)
or an aftermarket product for the same.

Canting the cleat itself, is an option as well.


Custom, ortho insoles would also be a potential solution.
