teigyr, i'm horrible about washing stuff so it wouldn't surprise me if they did shrink! the outer layer is like wool type stuff and the inner lining is poly. The reason I think they shrunk is because the liner is sticking out from the bottom, so it seems like the top layer shrunk. At least that's what I'm telling myself!
And congrats on the quick recovery during your hill run. Back before I hurt myself, it was so weird because I really enjoyed hill runs, it would suck while you were ascending but it felt soo good on the downhill.
