That would all depend on what the podiatrist advised you ... do you know what type of shoe you are looking for?
I would assume that if the insoles are correction a mechanical problem then you would be looking for a neutral shoe so as to not over/under correct what the insoles are doing. I would also think that if you are getting the correct size for you then you would need to remove and replace the insoles so that they fit correctly
I will however go back to my first point, after paying for the podiatrists time and advice and the insoles then it is they you should be asking rather than a bunch of weirdos on the internet
