Minimal, multi-purpose, a bit addictive, these Surfa flip-flops have wide, foot-hugging webbing straps, a soft fabric toe post and FitFlop's ‘magic’ supercushioned Microwobbleboard™ midsoles, making them the ultimate in relaxed cool.  Good with a wetsuit while you wax your board, with cut-off jeans at the beach bar, for to-and-from your yoga class… Upper Material:  Webbing (polyester) Lining Material:  Unlined Fastening:  Slip-on Outsole:  Slip-resistant rubber outsole Technology:  MICROWOBBLEBOARD Fit: Average to Wide   FOOTBED TECHNOLOGY Launched in our very first sandal ten years ago, our patent-pending, triple-density Microwobbleboard midsole was engineered by two pioneering British biomechanists. Delivering extraordinary comfort, it not only helps absorb shock but can also diffuse underfoot pressure, by instantly increasing the contact area of the foot to the midsole.
