FitFlop Women's Walkstar Classic Thong Sandal,Black,9 M US

When I saw these on Oprah I had my doubts about the claims that they would have any effect on my backside or legs. They did not and I can see no reason why they would. Other than being extremely comfortable and expensive when not purchased here, there is nothing "athletic" about the design of this flip flop.

The "fit" flop is nice and comfortable, but I think the name (and claims) are deceptive. I wear mine all the time because they are comfortable, but there is not any muscle toning going on aside from the usual benefits of walking.

I love these shoes! They are so comfortable. I wear mine all the time. I even sneak them into the office.

I have really been pleased at how these fit flops give such a workout when they are worn. It is best to only wear these a few hours at first as the strap between your toes kind of hurts. After that I had them on for one full day and couldn't figure out why my legs were a little sore the next day. I am used to them now and they are great!!!!

These flip flops are very comfortable and make me feel a burn after wearing them for long periods of time! I like that they can make one fit while being easy and comfortable!
