splints are not ordinarily designed for turn out use, but how one applies them is up to them. Bell boots are relatively inexpensive and should help. Overreaching is usually pretty obvious and often causes injures to the back of the fronts coronet area. Chipping of the lower hoof wall is usually a sign the hoofs need to be addressed (e.g., trimmed), and protection "above" isn't going to help.
There is just as much horse sense as ever, but the horses have most of it.
