Doing it without shoes does increase the mobility. It's a lot harder than it sounds. Check with your local physical therapist, they carry 3 different colored bands, a gray, a blue and a red. If you can get them local, they've got a pamphlet that shows the exercises to use with the bands. The 3 different colors just have increasing tension. If you can't get it local, I work at a hospital and can get the bands and the pamphlet and send it to you if you'd like. It really does make a difference.
