why we should wear insoles ?

why we should wear insoles? Let me make a metaphor

The only contact a car has with the road is through the tires on its wheels, so the condition  and alignment of the tires and wheels have a profound effect on the car's driving performance ,imagine the quality of a ride  in a car with  one unaligned wheel , if it's badly out of alignment,the  ride will be rough ,and the car will probably develop mechanical problems. in the same way, a poorly aligned  foot can make walking difficult and even painful ,and it can have profound effects on the rest of the body .
