If your talking about a lift on the outside of shoe....i had it done once by an old fashioned shoemaker/shoe repair...they glued something on the outer part of shoe, to correct overpronation..
Also had it at a ortho place that makes orthotics, and braces, they put the lift, glued a wedge to outer part of shoe..
Some very good shoe stores, specialising in hard to fit ppl, have orthotists, that take a prescription for orthotics..foot solutions have them
but if you can find a place that sells very good shoes, for hard to fit, they make or can glue something on, or they might be able to direct you to the right place...
Just wondering about the script, with the kind of place that would make braces and things, it may be hard to find a place like that
An old fashioned shoe maker , i know kind of becoming extinct, might be your best
Good luck
