OUR ORIGINAL MICROWOBBLEBOARD™ MIDSOLE Launched in our very first sandal seven 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.

Microwobbleboard™ sizing information


Instep sizing information
FitFlop footwear only comes in whole sizes. If your feet fall somewhere between, opt up a size if you have wide feet or a high instep, and down if you have narrow feet or a low instep. In the US, most people size down to the nearest whole size. In the rest of the world, people generally size up.

To ensure these fit, take 20-30 brisk walking steps in them, then look at your heels to make sure they are not being pushed off the back of the footbed. If they are, the upper straps are too tight across your instep and you need to SIZE UP (if a size up seems too long for your foot, please try another style).

Note: It is normal to have some space between your toes and the front of the footwear.
