The Electra sandal is FitFlop's bestselling sandal, as it perfectly balances effective exercise with just the right dash of bling. As with all FitFlop designs, the Electra is based around the muscle-toning MicroWobbleboard midsole that helps to tighten and tone your legs and bottom as you walk. Each step absorbs shock, burns extra calories and looks great too.

This new style from MBT packs all the punch of the original in a much prettier package. The neutral tones are equally at home with jeans or a crisp cotton skirt, so you get the health benefits without sacrificing on style. MBT's unique sole places the body in a natural state of instability that can otherwise only be achieved by walking barefoot on natural, uneven surfaces. So it forces you to use more muscles as you walk and improve your posture.
