FitFlop sandals claim to tone your calves, thighs and glutes with a specially designed midsole that functions like a mini wobbleboard to work your muscles as you walk. You'll notice the extra pull in some interesting muscle areas the minute you take a step.

While my gluteus maximus isn't minimus yet, I can notice more, uh, definition, in the three weeks I've been wearing my red and white FitFlops. And my legs look more shapely. At least in my opinion, which I respect.

$49.99 in red, black or white, women’s whole sizes 6-10.
