Why we buy shoes

I have recently bought a new pair of shoes that gave me pain.

Now the blisters have hardened and become thick ugly calluses, I no longer feel pain wearing those shoes.

So, should I leave the calluses be, let my feet keep their natural defence (though looking ugly) to spare myself further pain?

Or should I buff away the calluses, beautify my feet again, make them soft as ladies' feet are expected to be, and open them up to new pain?

Or maybe I should just forget about pretty shoes, and get myself a pair of Scholls?

Or maybe somewhere out there, there exist pretty shoes that cause no pain.
