Any decent coach or biomechanist will tell you that trying to fight this is futile.

Let me know of any National High Performance programme or Professional team that spend any time coaching pedalling technique!!!

----------------------
Typically the 'ball of the foot area' is firmly held a small distance above the axle of the pedal. And that distance is forced to remain constant (constrained) during the full rotation of the crank. Through ankle movement the rider can (and does) make small changes in the precise angle of the foot above the axle - but the rider cannot change the basic circular movement of the foot around the bottom bracket spindle.
For example, the foot is prevented (constrained) from moving diagonally UP from the 7 o'clock position to the 1 o'clock position.

Try pedalling in an actual square and let us know how you get on.

The movement of the legs when walking is very like that of natural pedalling and no constraining is needed for walking. This explains why the natural pedalling style is so ingrained in a rider's brain and muscles that coaches refuse to even consider the idea that a very different and more effective technique could exist. Cranks may constrain the movement of the legs but they do not constrain the torque generating technique of the two most powerful pedalling muscles (glutes and quads). This also explains why when cleats and toe-clips were invented riders were unable to avail of all they had to offer and as a result pedalling's dead spot sector is still in existence today.

Unsupported speculation.
