When I am fitting a wide orthotic device like an Inverted, I must place my fingers along the distal medial edge and make sure it is sitting on the base of the shoe. I do not want it to hang up on the edge, as that will tilt the whole orthotic device and jam up the first ray.
If that is the case, you have two choices. You can narrow the entire orthotic plate from medially, and lose some of your correction. Or, you can take off the distal medial corner only, like in a first ray cut-out, which maintains the original support.
