I very highly doubt they do anything. They just want to make money and they know they can sucker a lot of women out of their money by claiming that just wearing those shoes will get rid of cellulite. It says on there that's what they'll do "every minute you're wearing them". So I could sit on my butt all day watching TV and as long as I am wearing the shoes, they'll work? Doubt that. If you have issues with your bod, the only way to resolve them is to eat less, eat healthier, and get up off your lazy booty and get some exercise!
