First & foremost - I'm guessing by your attitude you've already started
- work towards correcting the state of not knowing much about hooves. Learn about anatomy & hoof function, about the various factors(such as diet & environment) that influence hoof health and learn about the pros & cons of some different approaches. Then you'll be in a better position to make objective decisions about her care. To that end, check out the link in my signature below for a start. There is plenty of good stuff available on line. I'd also consider finding/doing a good workshop/clinic to teach you the basics hands-on.
If you could post some pics of your horse's feet - the other link in my signature below - we could get a fair idea of what's going on. Without them, unfortunately a guess is the best you can get.
So my guesses are that the horse is dragging her toes because they're too LONG. Walls may be level with the sole at the ground surface, but stretched out too far forward. She may have 'dropped' soles, which despite a long hoof capsule has left her toes level with the sole. She might have body problems - in the shoulder or such - that are causing her to drag her toes.
If she's just enjoying paddock life, I wouldn't be too concerned with overwear. That's not likely but if she has worn her toes back into sole material, then this could well be problematic. If that were the case I'd consider protecting her toes until you have resolved the problem.
