Have you heard the term "Custom Made Orthotic" before? In most industries it would be something made very specific to your personal requirements. If it was a car it would be the color you want and have the size of engine with the performance package you want etc..
In the foot orthotic industry you cannot trust that to happen. Just go to the State Fair as one example and go up to the booth with foot orthotics. If it like the ones I have seen they will sell you a "custom made" foot orthotic for a good chunk of change. They will ask you what size you are to try one on and through the power of positive pigeonholing, they bring out your size and have you put it in your shoe to walk around.
Now consider that your foot was not casted, scanned nor did you have it heat molded to your foot. So what was "custom made"? Many shoe and foot orthotic stores do something similar.
Of course yours are custom made because you had a doctor (you name the type) cast or scan your foot and sent it into a lab and you paid a lot of money for them so they are officially "custom made". I would then ask you to put them side by side and check to see if they are identical. Often feet are not identical in angle or shape.

There are requirements in the industry should be met and here are some good ones to consider;

Thanks for listening to the sole of your foot.
