Navigating International Shoe Sizes
Shopping for footwear online from international brands can be tricky because sizing standards vary significantly across the US, UK, Europe, and Asia.
Key Factors in Foot Measurement
- Mondopoint (Centimeters / Millimeters): The most accurate physical measurement of foot length.
- US Sizing: Based on barleycorn increments (1/3 inch) with offset baselines for men and women.
- EU Sizing: Based on Parisian Points (2/3 cm or ~6.67mm).
Pro Tips for Accurate Fit
Always measure your feet in the late afternoon, as feet swell slightly throughout the day. Place your heel against a wall on a piece of paper, trace your longest toe, and measure the millimeter distance.
