Kind Reminder

To ensure the best fit, please review the sizing instructions below before placing your order.

How to Choose the Right Size

Measure your foot length from the heel to the tip of your longest toe.

If your measurement falls between two sizes, we recommend choosing the larger size.

Due to differences in foot shape, a deviation of up to 0.5 cm is considered normal.

Sizing Standard

All products are listed in European sizes (EU).

Please refer to the foot length (CM) provided in the size chart for accurate selection.

If you are unsure, kindly refer to the “How to Measure Foot Length” guide at the bottom of the size chart.

Important Note

The CM value shown on the shoe box or label does NOT represent actual foot length, and should not be used as the primary reference for sizing.
