They are useful to add specific EV's to areas, for example, if I wanted to train a Pokemon with 252 EV's in HP, I would need 25 HP Up's, but that only gives 250. Another 10 is too much, so just 2 easy to find and free wings are a better choice.

Go to a bridge where wings are available, and grab 2 for a total of 252 EV's
Now, if I wanted it to be EV trained like this:
I would need to have:
50 Battle Points
2 Muscle Wings
2 defense EV raising wings (I forgot the name, I'll edit later)
4 Swift Wings
It isn't hard to do, just takes some time. Much more accurate and less confusing.
If your Pokemon has PKRS, that's when you have to manually EV train on wild Pokemon.
Hope this helps anyone.
