How it fits

ECCO designs each shoe to fit the natural shape of the foot, for a comfortable, natural fit.

ECCO shoes come in European (EU) sizes. Each EU size covers a whole and a half US size — for example, a women’s EU 38 fits a US 7 or 7½. Measure both feet and let your longer foot decide your size.

Between sizes

Between sizes? Size up if you wear thick socks or orthotics, or you're on your feet all day. Choose the smaller size if you like a snug, athletic fit.

How to measure

Place a sheet of paper on the floor against a wall and stand on it with your heel against the wall.
Mark the tip of your longest toe.
Measure from the wall to the mark, then repeat with the other foot.
Match the longer measurement to the chart. Measure later in the day, wearing the socks you’ll wear with the shoes.
