bell boots might help. However, once I was riding a horse that overreached and we were just walking in the arena , he had bell boots on, and suddenly he stepped on the bell boot, and because his front foot was now pinned to the ground by his own rear foot, he went down on his knees and just laid me in the sand. Big surprise, but no hurt to me. But, after that, I didn't rde him in boots anymore.
If the front hooves have not enough break over, they will be delayed a tiny bit, which can mean the back foot catches them before they are broke over, and up and out of the way. So, maybe, just maybe, if the farrier thinks it's the right thing to do, shortening the toe and making more breakover might help. That's only if the farrier agrees that this is the issue.
