Shape ups actually works! I was skeptical because of the commercials, since the people wearing the shoes were super skinny and fit. However within four months or so I noticed that my legs, thighs and butt became very toned. Usually in order to get my lower body into shape like they are now, I would have to swim. How may you ask? The shoes are ridiculously heavy, that's right each shoe weighs at least half a pound. Imagine walking up and down the stairs with those puppies, who wouldn't get fit. Upside is that they do not cost around 100 dollars anymore, compared to the price they were at last year. Now they are around roughly $40-65. Another pro is that they give you an extra inch in your height. Since I'm 5'1, wearing them made me feel tall. Downside is that you can't run in them cus your very likely to sprain your ankle. Also the fabric on the inside isn't very durable. After only owning the shoes for about 7 months, the back inside area (where you slide in your feet into the shoe) tared apart and yellow sponge stuffing came out. All in all if you don't have time to go to the gym, have some extra cash laying around, why not. Maybe they fixed their poor quality... probably not, but never hurts to try out new products.
