OK---everyone, I need your input on this!

I have been eyeing the Sketchers Shape Ups for almost a year now---and when I asked my pain managment doctor about them (I have a very screwed up back and hip from a car accident) he encouraged me to get a pair. Now, I will tell you honestly that I hate sneakers in general, about the only time I wear them is when I am working out (said car wreck meant I had to wear only sneakers on my feet for almost two years post trauma, and I am one of those women who just loves pretty shoes!) I bought this pair at the Charlotte Women's Show last week:

and they are now on my feet as I head out the door to run errands. If I don't post for a few days, you will know I fell off them.

I'm curious, do any of you have these (not necessarily Sketchers Brand, any of the fitness shoes with the thick, rocker like soles)---how do you like them, do you notice a difference in your muscles? How much do you wear them (some people live in sneakers---I am not one of them), what's the best thing about them, what's the worst (they make me about 2 inches taller, and I am 5'9" barefoot!) Leave me a comment, and I will post again later this week with my experiences!
