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.

The upper bands on the FitFlop sandals do NOT stretch. In our sheepskin boots, expect the FitFlop FREEFOOT fit, in which your forefoot and toes will be held quite snugly (as they are in our sandals), but your heel will be looser behind to allow optimal biomechanically advantageous movement. You might think of it as heel slip, but in fact, it’s heel FREEDOM! (As long as they don’t rub you the wrong way, the fit is right.)

Q. If I am a half size should I go up or down in my FitFlop sandals?

A. FitFlop sandals have been designed to fit a standard-width UK foot and are graded in the traditional way.

The webbing is designed to hold the foot quite high up across the instep and will not stretch over time. Thus, FitFlop fit is a function of arch height and instep height.

Our experience so far has shown that Europeans have a slightly higher instep height and tend to need to size up whereas Americans have a lower instep height and need to size down. The length of the sole is quite generous so going half a size down should not cause a length issue.
