Ok here's my pathetic attempt at giving my humble opinion after humming and hawing over my fellow BDer's posts.

In my opinion they did have wings.

Now to incorporate some proof to my flimsy theory, I agree that evolution would be out, though at first my proof and opinion was going to be that, [I]well Ostriches and Emus are huge birds but their weight and over all proportions prevent them from flying to any extentso yes the Balrogs could have had wings, but aside from evolution the weight theory can still be put into effect for obvious reasons, they were freakin' huge!

Now for them being able to have changed forms, Morgoth's Maia, very much like himself, would have lost their ability or capability to perform certain tasks, after all due to Morgoth's downfall he was only able to pervert and contort and not make things of his own. Perhaps it could be the same for his followers, maybe after a period of time they were unable to change to anything else and unable to use their wings in flight due to them no longer being of the Light, or perhaps the wings could potentially be in a stunted form from their inability to have changed further due to their degradation, thus not allowing them flight.

So I believe the Balrogs had wings but were unable to fly.
I think thats all I have to say for now untill I think of something better.
