She certainly seems a little unsteady, but I am so impressed that she can even wear high boots at all anymore--I'm sure she is in quite a bit of pain most of the time. I work at a specialty shoe/athletic retailer and we see so many people with major foot, leg and back problems due to bad shoes. I for one would love to fit Stevie in a good pair of orthotics and running shoes so she can run around like she used to on stage
I really hope she is taking care of herself and takes those boots off immediately after the show. I want Stevie to be able to keep on rockin'! Beauty is pain, people!
