I don't have scoliosis but I do have an old back injury. I found that regular shoes encourage my posture "forward" which puts my body weight on my upper back instead of centered (because the heel isn't zero-drop). Minimalist shoes encourage proper spinal alignment in my experience.
If you have foot issues too, I'd suggest Merrells. Been wearing mine for two years and it's helped my body mechanics immensely without the "awkward" of Five Fingers.
