Like i mentioned, I think many of us have problems in some way with lifting our feet, some who have that nerve effected, they literally cannot lift, have 0 dorsi flexion. As in my case, I mostly have problems when my legs go into exhaustion, do beyond my limits. I can point my toes up at will, but once I reach that point of having to really concentrate on walking I drag a foot. While it may seem to be foot drop, it's not necessarily requiring a orthotic remedy, I'm speaking of my case. I'm sure if your doctor feels you can benefit from an orthotic remedy, he'll suggest it, or he may feel physical therapy would be enough. You should ask him your options.
