Most luxury footwear uses EU sizing. Always refer to the designer’s fit notes, as sizing may vary slightly by brand and style.

How to Measure Your Foot

Place your foot flat on a piece of paper against a wall.
Mark the tip of your longest toe.
Measure the distance from the wall to the mark in centimeters (cm).
Match that measurement to the JP (cm) column in the chart above.

Example explanation you could place below the chart:

The JP column represents foot length in centimeters. If your foot measures approximately 25 cm, you would typically wear EU 39 / US Women 8. Because designer sizing can vary slightly, this method provides the most accurate reference when selecting luxury footwear.
