Measuring ritual

How to find your fit

Stand on paper

Place your full weight on one foot. Keep the heel flat and posture natural.

Mark heel to toe

Mark the back of the heel and the longest toe. Measure the distance in centimeters.

Use the larger foot

If one foot is slightly longer, choose the size that matches the larger measurement.

Styling note

Between two sizes?

Choose the larger size for pointed toes, structured heels, or if you prefer a more relaxed fit. For open-back silhouettes, your usual size will often feel most natural.

Shop Heels

Heels

Structured heels can feel more precise around the toe box. If your measurement is between sizes, select the larger option.

Sandals

Open silhouettes allow slightly more flexibility. Choose your closest foot-length match for the cleanest fit.

Daily wear

For long days, events, or extra comfort, allow a little room at the front rather than choosing a tight fit.
