It very well could be a shoulder or hip issue. Or, the amo could care less. Not all lameness is hoof related, nor are all amo straight shooters.
I also live in a very Amish area, and lets just say, not all are equal. A good honest Amish horseman would look over the whole horse, before even trimming. They're the lively hood of the handler. Just this past weekend, I watched an Amish buggy leaving wallyworld (yeah I know) the horse couldn't pull the wagon up the hill from a dead stop. It was loaded. He got off, led it, ,) kinda, and off they went.
Guess what my point is, Amish or not, have someone else look.
Could be anything really.
