Fit Flop Surfa Flip-FlopAt FitFlop, we believe that when your feet feel great, you feel like you can do anything. 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 our first FitFlop sandal. Over twenty million pairs have been sold since we first started making shoes.
