Wearing the wrong length/width/shape shoe will indeed mess up your feet. Wearing the correct size/shape shoe for your individual feet will not give such issues. Additionally different shoes do different things so wearing the best one for the activity being done will yield the best results.
Changing to different shoes every day is also really important to dry out sweat and avoid repetitive injuries caused by wearing the same shoe such as corns, callouses, deformations, stress fractures, etc.
That said, cheap material and lack of local shoemakers, makes finding the good/best fit incredibly difficult if not impossible. Couple with feet size shifting throughout the day (swelling) and the changes over a lifetime, really makes everything more complicated. And that’s not even acknowledging prices or fashions.

There’s also a second book called Parable of the Talents.
