Anyone???????

So wait my regular flip-flops won't tone my butt?  

Jk, I have no clue but those pink ones are crazy weird! haha

They did a story on the fitflops and proved that they dont work. Actually there was a fitness trainer on there stating that the fit flop actually can do more harm than good. Something about the area under the ball of the foot being softer, its supposed to mimic walking in sand I guess? Anyhow, your leg is supposed to have to work harder to compensate for the extra depression created by the soft spot. The people who they had test them said they were really comfy, but they didnt notice any difference after a month.

lol and those first ones just look damn dangerous!

I have some fitflops and I can definately tell a difference. They are super comfy and really do work your muscles.

I love my fitflops! I felt a difference with them, especially when I first started using them. But I have to admit, they are also very comfy, so I tend to use them all of the timeand I've pretty much worn my first pair out. Ido notice that they dofeel "easier" now, but I liked them enough, thatI just ordered TWO new pairs!
