In 2006 FitFlop founder Marcia Kilgore set her mind on a mission – to create the most comfortable footwear in the world. Collaborating with two British biomechanists she created a triple-density MICROWOBBLEBOARD midsole, and launched it in FitFlop's first FitFlop sandal. Over twenty million pairs have been sold since we first started making shoes. (And we’re repeatedly told – by happy customers – that we make the most comfortable footwear in the world.) FitFlop's patent-pending, original MICROWOBBLEBOARD midsole technology fuses three diagonal sections of multi-density EVA into a single, seamless, underfoot platform to help absorb shock, diffuse underfoot pressure, and make your feet feel amazing!
