FitFlop's Rally reworked for a slightly sportier feel. This X version boasts more detailing: paneling, double stitching, vulcanized-effect soles, and breathability holes at the front. But it retains the timeless 'tennis shoe' shape of the original, and the same superb ergonomic tech – ultra-light, flexible FitFlop Anatomicush™ midsoles that move with your feet.
