I'm by no means an expert in theoretical physics, but if I have a grasp of current trends, I wouldn't say that string theory is on shaky grounds, only that there is, as you said, little evidence to support it because it is so hard to test. The "strings" in string theory are ridiculously small on the order of 10^-35 meters in length (in the so called "Planck realm"). That being said, the hopes of being able to see these things are very slim. You may say, "how about how strings act on a macro level then, can't you show the existance of string theroy that way?" The problem is, string theory is used to describe on a micro level the things we see on a more tangible level, so you just have a loop of saying that things act the way they do because of string theory, even though you set about establishing string theory to explain how the macro environment works on a microscopic level. The only real progress I know of to prove the existance of string theory is in supersymmetry and particle accelerators. If you can show the pairing of a boson and fermion, which is at the heart of supersymmetry, a "subset" of string theory, you can begin to show the existance of strings themselves. The problem is no one has conclusively begun to show this pairing. Okay, hope that helps.
