The FF Supertone™ is a muscle-toning, energizing, shock-absorbing sneaker from Fit Flop. After more than a year in engineering, Fit Flop’s product technology & design team has managed the perfect merger: amalgamating the patent-pending, muscle-loading Microwobbleboard technology with the all-weather wearability of a classically-shaped, trend-conscious leather sneaker. Cleverly designed to hide the ‘toning sole’ (so you can wear it everywhere without anybody knowing you’re getting a workout) the FF Supertone™ has an ageless, cool, go-everywhere style – with Fit Flop’s thigh-toning, foot-flexing, bottom-benefiting biomechanics built-in. Best of all – it doesn’t look like a shoe that’s ‘good for you’.
