My friend had on these cute flip flops and told me that they are designed with the base of a tennis shoe, so the foot has support while walking, but with a cute top. I went on the website and found some pretty cute shoes.
These are the ones I bought and I love them.They are cute and I have received really great compliments on them, and I am not lying they totally work. My butt has never been perkier (well at least not since high school, those were the days!) and my abs hurt after a day of wearing them and my posture is better. They must be the wonder shoe :) They aren't my replacement for exercise, though I wish that were true, but I think they help keep me standing upright during the day and keep my feet from killing when I walk. They are great for people who walk lots of places, want to look cute, and need their feet to not kill.
This is what the fit flop makers claim the shoe does...
I am a believer.
