Hurry! Whilst Stocks Last The Flip Flop with the Built in Gym

Half sexy sandal, half muscle toning trainer this is the hot new must have for summer. But be quick – they are already selling out.

Every step you take in the Fit Flop helps trim your legs. The Fit Flop's uniquely built multi-density midsole activates the muscles midstep to help tone your thighs, your calves and your glutes. In fact, Fit Flops are biomechanically engineered to absorb shock, lessen joint strain, and recreate the gait of barefoot walking - but with a powerful new built-in micro-wobbleboard workout-enhancing effect. These are like the MBT but in a much more attractive flip flop style.

Available in UK women's sizes 4-8 in Red and Black (Sorry, blue is not available until July). RRP £36.

The Fit Flop is launching in the UK in early May 2007 at King's Road Sporting Club, Harvey Nichols, Selfridges, Bliss Spa, Totally Fitness, Running Bare, sweatyBetty and Ugs and Kisses. It is available in the US at selected Bath & Body Works stores.
