I love these shoes. I did not buy them, because of the toning claims. I purchased them because someone I know told me how they keep your body better aligned, which helps reduce joint pain. I use them for work (where I stand almost all day), and for working out (weights and cardio). From the point I put them on I felt a lot less pressure on my joints... my hip and knee pain was gone. My only complaint is that most options have color. I purchased the black/silver and the silver/blue, because they go with more of my clothes. I can see myself buying more of these, because they are so cozy.
