Really, it all depends on the orthotic. Theortetically, you ought to be able to go with a neutral shoe + your orthotics, since the orthotic was made to correct your biomechanics specifically. "Motion control shoes", for example, do some generic correction that may or may or may not be appropriate. You'll need to talk with your orthotist (the guy who actually made your orthotics) and your doc to find out the real scoop in your case. Most of the orthotists here at Georgetown recommend neutral shoes once you get the orthotics fitted properly
For example, with orthotics I now run in NB900's, which is about as neutral as it gets without any problem. Much nicer than those damn clodhoppers I needed in the past.
YMMV, of course.
